The concept of an atmospheric front is usually understood as a transition zone in which adjacent air masses with different characteristics meet. The formation of atmospheric fronts occurs when warm and cold air masses collide. They can extend for tens of kilometers.
Air masses and atmospheric fronts
Atmospheric circulation occurs due to the formation of various air currents. Air masses located in the lower layers of the atmosphere are capable of combining with each other. The reason for this is general properties these masses or identical origin.
Change weather conditions occurs precisely because of movement air masses. Warm ones cause warming, and cold ones cause cooling.
There are several types of air masses. They are distinguished by the source of their occurrence. Such masses are: arctic, polar, tropical and equatorial air masses.
Atmospheric fronts arise when different air masses collide. Collision areas are called frontal or transitional. These zones instantly appear and also quickly collapse - it all depends on the temperature of the colliding masses.
The wind generated by such a collision can reach a speed of 200 km/k at an altitude of 10 km from earth's surface. Cyclones and anticyclones are the result of collisions of air masses.
Warm and cold fronts
Warm fronts are considered to be fronts moving towards cold air. The warm air mass moves along with them.
As warm fronts approach, there is a decrease in pressure, thickening of clouds and heavy precipitation. After the front has passed, the wind direction changes, its speed decreases, pressure begins to gradually rise, and precipitation stops.
A warm front is characterized by the flow of warm air masses onto cold ones, which causes them to cool.
It is also quite often accompanied by heavy rainfall and thunderstorms. But when there is not enough moisture in the air, precipitation does not fall.
Cold fronts are air masses that move and displace warm ones. There are cold fronts of the first kind and cold fronts of the second kind.
The first type is characterized by the slow penetration of its air masses under warm air. This process forms clouds both behind the front line and within it.
The upper part of the frontal surface consists of a uniform cover of stratus clouds. The duration of the formation and decay of a cold front is about 10 hours.
The second type is cold fronts moving at high speed. Warm air is instantly replaced by cold air. This leads to the formation of a cumulonimbus region.
The first signals of the approach of such a front are high clouds that visually resemble lentils. Their formation occurs long before his arrival. The cold front is located two hundred kilometers from where these clouds appear.
A cold front of the 2nd type in summer is accompanied by heavy precipitation in the form of rain, hail and squally winds. Such weather can extend for tens of kilometers.
In winter, a cold front of the 2nd type causes a snowstorm, strong wind, chatter.
Atmospheric fronts of Russia
The climate of Russia is mainly influenced by the Arctic Ocean, the Atlantic and the Pacific.
In summer, Antarctic air masses pass through Russia, affecting the climate of the Ciscaucasia.
The entire territory of Russia is prone to cyclones. Most often they form over the Kara, Barents and Okhotsk seas.
Most often, there are two fronts in our country - the Arctic and the polar. They move south or north during different climatic periods.
The southern part of the Far East is influenced by the tropical front. Heavy rainfall on middle lane Russia are caused by the influence of the polar dandy, which operates in July.

Characteristics of hurricanes, storms, tornadoes
Hurricanes, storms, tornadoes are wind meteorological phenomena, belong to natural natural disasters , can cause great material damage and lead to loss of life.
Wind- movement of air relative to the earth's surface, resulting from uneven distribution of heat and atmospheric pressure. The main indicators of wind are direction (from a high pressure zone to a low pressure zone) and speed (measured in meters per second (m/s; km/h; miles/hour).
To denote the movement of wind, many words are used: hurricane, storm, gale, tornado... To systematize them, they use Beaufort scale(developed by the English admiral F. Beaufort in 1806) , which allows you to very accurately estimate the strength of the wind in points (from 0 to 12) by its effect on ground objects or on waves at sea. This scale is also convenient because it allows you to quite accurately determine the wind speed without instruments based on the characteristics described in it.
Beaufort scale (Table 1)
| Beaufort points | Wind speed, m/s (km/h) | Wind action on land | ||
| On the land | On the sea | |||
| Calm | 0,0 – 0,2 (0,00-0,72) | Calm. Smoke rises vertically | Mirror smooth sea | |
| Quiet breeze | 0,3 –1,5 (1,08-5,40) | The direction of the wind is noticeable by the direction of the smoke, | Ripples, no foam on the ridges | |
| Light breeze | 1,6 – 3,3 5,76-11,88) | The movement of the wind is felt by the face, the leaves rustle, the weather vane moves | Short waves, crests do not capsize and appear glassy | |
| Light breeze | 3,4 – 5,4 (12,24-19,44) | Leaves and thin branches of trees sway, the wind flutters the upper flags | Short, well-defined waves. The ridges, overturning, form foam, and occasionally small white lambs are formed. | |
| Moderate breeze | 5,5 –7,9 (19,8-28,44) | The wind raises dust and pieces of paper and moves thin tree branches. | The waves are elongated, white caps are visible in many places. | |
| Fresh breeze | 8,0 –10,7 (28,80-38,52) | Thin tree trunks sway, waves with crests appear on the water | The waves are well developed in length, but not very large; whitecaps are visible everywhere. | |
| Strong breeze | 10,8 – 13,8 (38,88-49,68) | Thick tree branches sway, wires hum | Large waves begin to form. White foamy ridges occupy large areas. | |
| strong wind | 13,9 – 17,1 (50,04-61,56) | The tree trunks are swaying, it’s difficult to walk against the wind | The waves pile up, the crests break off, the foam lies in stripes in the wind | |
| Very strong wind (storm) | 17,2 – 20,7 (61,92-74,52) | |||
| Storm (strong storm) | 20,8 –24,4 (74,88-87,84) | |||
| Severe storm (full storm) | 24,5 –28,4 (88,2-102,2) | |||
| 28,5 – 32,6 (102,6-117,3) | ||||
| Hurricane | 32.7 or more (117.7 or more) | Heavy objects are carried by wind over considerable distances | The air is filled with foam and spray. The sea is all covered with stripes of foam. Very poor visibility. |
Characteristics of atmospheric vortices
| Atmospheric vortices | Local name | Characteristic |
| Cyclone (tropical and extratropical) - vortices in the center of which there is low pressure | Typhoon (China, Japan) Bagwiz (Philippines) Willy-Willy (Australia) Hurricane (North America) | Vortex diameter 500-1000 km Height 1-12 km Diameter of calm area ("eye of the storm") 10-30 km Wind speed up to 120 m/s Duration of action - 9-12 days |
| A tornado is an ascending vortex consisting of rapidly rotating air mixed with particles of moisture, sand, dust and other suspended matter, an air funnel descending from a low cloud onto a water surface or land | Tornado (USA, Mexico) Thrombus (Western Europe) | Height - several hundred meters. Diameter - several hundred meters. Travel speed up to 150-200 km/h Rotation speed of vortices in the funnel up to 330 m/s |
| Squall - short-term whirlwinds that occur before cold weather atmospheric fronts, often accompanied by rain or hail and occurring in all seasons of the year and at any time of the day. | Storm | Wind speed 50-60 m/s Duration up to 1 hour |
| Hurricane - big wind destructive force and of significant duration, occurring mainly from July to October in the zones of convergence of the cyclone and anticyclone. Sometimes accompanied by showers. | Typhoon (Pacific) | Wind speed more than 29 m/s Duration 9-12 days Width - up to 1000 km |
| A storm is a wind whose speed is less than a hurricane. | Storm | Duration - from several hours to several days Wind speed 15-20 m/s Width - up to several hundred kilometers |
Hurricane
A hurricane is a fast movement of wind, with a speed of 32.7 m/s (117 km/h), although it can exceed 200 km/h (12 points on the Beaufort scale) (Table 1), with a significant duration of several days ( 9-12 days), continuously moving over the oceans, seas and continents and possessing great destructive power. The width of the hurricane is taken to be the width of the catastrophic destruction zone. Often this zone is supplemented with an area of storm force winds with relatively little damage. Then the width of the hurricane is measured in hundreds of kilometers, sometimes reaching 1000 km. Hurricanes occur at any time of the year, but are most common from July to October. In the remaining 8 months they are rare, their paths are short.
A hurricane is one of the most powerful manifestations of nature; its consequences are comparable to an earthquake. Hurricanes are accompanied by precipitation large quantity precipitation and lower air temperatures. The width of the hurricane ranges from 20 to 200 kilometers. Most often, hurricanes sweep over the USA, Bangladesh, Cuba, Japan, the Antilles, Sakhalin, and the Far East.
In half of the cases, the wind speed during a hurricane exceeds 35 m/sec, reaching 40-60 m/sec, and sometimes up to 100 m/sec. Hurricanes are classified into three types based on wind speed:
- Hurricane(32 m/s or more),
- strong hurricane(39.2 m/s or more)
- violent hurricane (48.6 m/s or more).
The reason for such hurricane winds is the emergence, as a rule, on the line of collision of fronts of warm and cold air masses, powerful cyclones with a sharp pressure drop from the periphery to the center and with the creation of a vortex air flow moving in the lower layers (3-5 km) in a spiral to the middle and upwards, in the northern hemisphere - counterclockwise. Forecasters assign each hurricane a name or four-digit number.
Cyclones, depending on the place of their origin and structure, are divided into:
1) Tropical cyclones found over warm tropical oceans, during the formation stage they usually move to the west, and after formation ends they bend towards the poles. A tropical cyclone that has reached unusual strength called:
-tropical storm if he is born in Atlantic Ocean and the adjacent seas. Northern and South America. Hurricane (Spanish huracán, English hurricane) named after the Mayan god of wind Huracan;
- typhoon – if it originated over the Pacific Ocean. Far East, Southeast Asia;
- cyclone – in the region Indian Ocean.
Rice. Structure of a tropical cyclone
Eye - central part a cyclone in which air descends.
The eye wall is a ring of dense thunderstorms cumulus clouds surrounding the eyes.
The outer portion of a tropical cyclone is organized into rain bands—bands of dense thunderstorm cumulus clouds that slowly move toward the center of the cyclone and merge with the eye wall.
One of the most common definitions of cyclone size, which is used in various databases, is the distance from the center of circulation to the outermost closed isobar, this distance is called radius of the outer closed isobar.
2) Temperate latitude cyclones can form both over land and over water. They usually move from west to east. Characteristic feature Such cyclones are characterized by their great “dryness”. The amount of precipitation during their passage is significantly less than in the zone of tropical cyclones.
3) The European continent is affected by both tropical hurricanes originating in the central Atlantic and cyclones of temperate latitudes.
Rice. Hurricane Isabel of 2003, photograph from the ISS - the characteristic eye of a tropical cyclone, the eye wall and surrounding rain bands can be clearly seen.
Tempest (storm)
Tempest (storm) is a type of hurricane, inferior in strength. Hurricanes and storms differ only in wind speed. A storm is a strong, long-lasting wind, but its speed is less than that of a hurricane 62 - 117 km/h (8 - 11 points on the Beaufort scale). A storm can last from 2-3 hours to several days, covering a distance (width) from tens to several hundred kilometers. A storm that breaks out at sea is called a storm.
Depending on the color of the particles involved in the movement, they distinguish: black, red, yellow-red and white storms.
Depending on the wind speed, storms are classified:
| Beaufort points | Verbal definition of wind force | Wind speed, m/s (km/h) | Wind action on land | |
| On the land | On the sea | |||
| Very strong wind (storm) | 17,2 – 20,7 (61,92-74,52) | The wind breaks tree branches, it is very difficult to walk against the wind | Moderately high, long waves. Spray begins to fly up along the edges of the ridges. Stripes of foam lie in rows downwind. | |
| Storm (strong storm) | 20,8 –24,4 (74,88-87,84) | Minor damage; the wind tears off smoke hoods and tiles | High waves. The foam falls in wide dense stripes in the wind. The crests of the waves capsize and crumble into spray. | |
| Severe storm (full storm) | 24,5 –28,4 (88,2-102,2) | Significant destruction of buildings, trees are uprooted. Rarely happens on land | Very high waves with long, downward-curving crests. The foam is blown up by the wind in large flakes in the form of thick stripes. The surface of the sea is white with foam. The crash of the waves is like blows. Visibility is poor. | |
| Fierce storm (fierce storm) | 28,5 – 32,6 (102,6-117,3) | Large destruction over a large area. Very rarely observed on land | Exceptionally high waves. Vessels are hidden from view at times. The sea is all covered with long flakes of foam. The edges of the waves are blown into foam everywhere. Visibility is poor. |
Storms are divided:
1) Vortex– are complex vortex formations caused by cyclonic activity and spreading over large areas. They are:
- Snow storms (winter) are formed in winter. Such storms are called blizzards, blizzards, and blizzards. Accompanied by severe frost and blizzards, they can move huge masses of snow over long distances, which leads to heavy snowfalls, blizzards, and snow drifts. Snow storms paralyze traffic, disrupt energy supplies, and lead to tragic consequences. The wind helps to cool the body, causing frostbite.
- Squalls – occur suddenly and are extremely short in duration (several minutes). For example, within 10 minutes the wind speed can increase from 3 to 31 m/sec.
2) Stream storms– these are local phenomena of small distribution, weaker than vortex storms. Most often they pass between chains of mountains connecting valleys. Divided into:
- Stock – the air flow moves down the slope from top to bottom.
- Jet – air flow moves horizontally or uphill.

Tornado (tornado)
Tornadoes (in English terminology, tornadoes from Spanish. tornar"twirl, twist") is an atmospheric vortex in the form of a dark arm with a vertical curved axis and a funnel-shaped expansion in the upper and lower parts. The air rotates at a speed of 50-300 km/h counterclockwise and rises upward in a spiral. Inside the flow, the speed can reach 200 km/h. Inside the column there is a low pressure (rarefaction), which causes suction, lifting up everything encountered along the way (earth, sand, water, sometimes very heavy objects). The height of the sleeve can reach 800 - 1500 meters, the diameter - from several tens above water to hundreds of meters above land. The length of the tornado’s path ranges from several hundred meters to tens of kilometers (40 – 60 km). The tornado spreads following the terrain, the speed of the tornado is 50 - 60 km/h.
A tornado arises in a thundercloud (in the upper part it has a funnel-shaped expansion that merges with the clouds) saturated with charged ions and then spreads in the form of a dark sleeve or trunk towards the surface of the land or sea. When a tornado descends to the surface of the earth or water, its lower part also becomes expanded, similar to an overturned funnel. Tornadoes occur both over the water surface and over land, much more often than hurricanes, usually in the warm sector of a cyclone, often before a cold front. Its formation is associated with a particularly strong instability of the regular distribution of atmospheric air temperatures over altitude (atmospheric stratification). It is often accompanied by thunderstorms, rain, hail, and a sharp increase in wind.
Tornadoes are observed in all regions of the globe. They most often occur in Australia, Northeast Africa, and are most common in America (USA), in the warm sector of a cyclone before a cold front. The tornado moves in the same direction as the cyclone. There are more than 900 of them a year, with most of them originating and causing the most damage in the “Valley of Tornadoes.”
Tornado Valley extends from West Texas to the Dakotas, 100 miles north to south and 60 miles east to west. Warm, moist air coming from the north from the Gulf of Mexico meets dry, cold wind moving from the south from Canada. Huge clusters of thunderclouds begin to form. The air rises sharply inside the clouds, cools there and descends. These flows collide and rotate relative to each other. A thunderstorm cyclone arises, in which a tornado is born.
Classification of tornadoes
Scourge-like - This is the most common type of tornado. The funnel looks smooth, thin, and can be quite tortuous. The length of the funnel significantly exceeds its radius. Weak tornadoes and tornado funnels that descend into the water are, as a rule, whip-like tornadoes.
Vague- look like shaggy, rotating clouds reaching the ground. Sometimes the diameter of such a tornado even exceeds its height. All large diameter craters (more than 0.5 km) are vague. Usually these are very powerful vortices, often composite. Causes enormous damage due to large sizes and very high wind speeds.
Composite- 1957 Dallas composite tornado. May consist of two or more separate clots around a main central tornado. Such tornadoes can be of almost any power, however, most often they are very powerful tornadoes. They cause significant damage over large areas. Most often form on water. These funnels are somewhat related to each other, but there are exceptions.
Fiery- These are ordinary tornadoes generated by a cloud formed as a result of a strong fire or volcanic eruption. It was precisely such tornadoes that were first artificially created by man (the experiments of J. Dessens (Dessens, 1962) in the Sahara, which continued in 1960-1962). They “absorb” tongues of flame that stretch towards the mother cloud, forming a fiery tornado. A fire can spread tens of kilometers. They can be whip-like. Cannot be fuzzy (fire is not under pressure, like whiplash tornadoes).
Mermen- these are tornadoes that formed over the surface of oceans, seas, and in rare cases lakes. They “absorb” waves and water, forming, in some cases, whirlpools that extend towards the mother cloud, forming a waterspout. They can be whip-like. Just like fire ones, they cannot be vague (the water is not under pressure, like in scourge-like tornadoes).
Earthen- these tornadoes are very rare, formed during destructive disasters or landslides, sometimes earthquakes above 7 on the Richter scale, very high pressure drops, very rarefied air. A whip-like tornado is located with the “carrot” (thick part) to the ground, inside a dense funnel, a thin stream of earth inside, a “second shell” of earthen slurry (if there is a landslide). In the case of earthquakes, it lifts stones, which is very dangerous.
Snowy
- These are snow tornadoes during a severe snowstorm.
Rice. A tornado and a cavitation cord behind a radial-axial turbine and the distribution of speed and pressure in the cross sections of these vortex formations.
Anticyclones. Anticyclones are areas of high atmospheric pressure with closed isobars, with a maximum pressure in the center of up to 1070 mb and a corresponding distribution of air currents. The diameter of the anticyclone can reach several thousand kilometers. Horizontal pressure gradients in anticyclones are directed from the center to the periphery, and the wind, deviating from the pressure gradient in the northern hemisphere to the right, blows around the center of the anticyclone clockwise, and in southern hemisphere, deviating to the left, is directed counterclockwise.
In the central part of the anticyclone, as a rule, partly cloudy, dry weather with weak wind prevails.
Concept and types, 2018.
Towards the periphery of the anticyclone, cloudiness increases and wind speed increases. The temperature in the western part of the anticyclone, where southern winds dominate (in the northern hemisphere), is usually higher than in the eastern part with its northern winds. In the anticyclone it is sharply expressed diurnal cycle meteorological elements, especially temperature and humidity. In summer, with strong convection in the anticyclone, thunderstorms sometimes occur. In exceptional cases, drizzle, fog and stratus clouds may be observed in the anticyclone.
Cyclones. A region is called a cyclone low blood pressure with closed isobars, with minimum pressure in the northern hemisphere and clockwise in the southern hemisphere.
Concept and types, 2018.
Cyclones vary in size and depth: one should be about 100 miles in diameter, another over 2000 miles. The pressure at the center of most cyclones ranges from 980 to 1010 mb, but in some cases the pressure drops to 935 mb. and below.
Cyclones can move in almost any direction, but most often they are directed to the northeast in the northern hemisphere and to the southeast in the southern; their speed ranges from 10 to 40 knots, sometimes reaching 60 knots. When cyclones are filled (occluded), their speed decreases.
Tropical cyclones are one of the most dangerous and least studied natural phenomena. They are relatively small in size, ranging from 20 to 600 miles in diameter, but very deep atmospheric vortices. They have high kinetic energy (with low pressure and hurricane force winds, forming a counterclockwise circulation in the northern and clockwise in the southern hemisphere with a slight deviation towards the center). Such a cyclone as a whole (or center) has a forward motion and is often the cause of great excitement, much greater than in the most severe storms of temperate latitudes.
The speed of a tropical cyclone varies from 70 to 240 miles per day, increasing with increasing latitude. Atmosphere pressure in a tropical cyclone from the periphery to the center it drops to 950-970 mb, and in some cases it drops even lower, the wind speed, on the contrary, increases and near the central zone of the tropical cyclone reaches its highest values, equal to 40-60 m/sec and even more. However, in the very central zone of a tropical cyclone with a diameter of 20 to 30 miles, the wind weakens to calm.
The passage of a tropical cyclone is always accompanied by heavy clouds, very heavy and prolonged downpours and significant waves. In the central zone of a tropical cyclone (the eye of the storm), the sky is usually clear or covered with thin stratus clouds; The excitement here takes on the character of a strong crush. posing a great danger to the ship. Tropical cyclones occur in all oceans.
The main centers Their origins and local names are as follows:
· Caribbean Sea and Gulf of Mexico. The cyclones that arise here are called Antillean hurricanes
· Philippine Islands region, South China Sea tropical cyclones are called typhoons
· Arabian Sea and Bay of Bengal, where tropical cyclones have no local name
· Indian Ocean off the coast of Australia. Here tropical cyclones are called "willy-willy"
· in the Pacific Ocean off the west coast of Mexico - cordonazo
· in the Philippines - baguyo, or baruyo
· In the southern part of the Indian Ocean, east of the island Madagascar.
Posted on ref.rf
The local name for tropical cyclones is ʼʼorcansʼ.
Tropical cyclones often originate in the open ocean, usually between 5 and 20° latitude, at the boundaries of the zone of prevailing light winds and calms and in monsoon areas. At the first stage of their movement, tropical cyclones move at a low speed of 10-20 km/h to the west, then the speed increases to 30-40 km/h or more.
Then, increasingly deviating to the right in the northern hemisphere and to the left in the southern hemisphere, they begin to move to the northwest and southwest, respectively. Having reached the border of the trade wind zone, i.e. to approximately 15-30°, northern and southern latitudes, tropical cyclones, if they have not yet filled by that time, change the direction of movement and begin to move to the northeast in the northern hemisphere and to the southeast in the south.
Concept and types, 2018.
Some tropical cyclones, however, do not change direction but continue to move in a northwest or southwest direction until they reach the mainland. As it enters temperate latitudes, the cyclone gradually fills and slows down its movement. But when a cyclone penetrates into a system of colder air (into the region of the polar front), it transforms: it deepens, speed increases (sometimes up to 60 km/h), the zone of storm winds expands, etc. And as an extratropical vortex, it can shift at fairly high latitudes. As the tropical cyclone enters the continent, it quickly weakens and dies out. Tropical cyclones are most often observed in the northern hemisphere from August to September, and in the southern hemisphere in the region Pacific Ocean- from January to July, in the Indian Ocean - from November to April. The exception is the northern Indian Ocean, where tropical cyclones are more common from May to December.

“...the entire geosphere has been in the grip of this chiral spiral vortex field (SVP) for billions of years, which in reality is the force agent of the solar atmosphere with all the complications in connection with the manifestations of solar activity. The speed of propagation of a spiral vortex field (SVP) depends on the density, structure and mass of matter overcome (from 3-1010 cm s-1 in the solar core to (2 ^10)-107 cm-s-1 in terrestrial conditions). In the solar atmosphere, the SVP velocity with the primary one is the earth's interior, since, for example, the biosphere is located directly above this source. The temperature in the earth's core is not high enough (~ 6140K) for the generation of primary vortex quanta (spirons), however, the Earth, constantly irradiated by SVIR flows (104 erg-cm-2s-1), continuously receives a flow of solar vortex energy (~ 1.3-1015 W ). Observations indicate that the geoid is a low-Q resonator for SVVI; ~ 0.3-1015 W is retained in it.”

By fractality to the rotation of various geometric shapes
The most complex, but promising classification of ethereal vortices is proposed in David Wilcock’s book “The Science of Unity”. He believes that all vortices, to one degree or another, approach different geometric shapes. And these forms do not arise by chance, but according to the laws of volumetric propagation of vibration. From here we can talk about vortices, fractal to the rotation of various geometric figures. Geometric figures can be conditionally combined with each other.
As a result, such combinations and rotations with different angles of inclination to the plane give rise to the following figures. http://www.ligis.ru/librari/670.htm
The basis of such figures, as well as the basis of the vortices that arise during their rotation, are the Harmonic proportions of the Platonic Solids. D. Wilcock classified these forms as:
This approach is an elegant combination of basic crystal shapes and vortices. As will be shown later, “there is something in this.” http://www. 16pi2.com/joomla/
