What is anticyclone | Types and varieties of anticyclones

The study of atmospheric phenomena, including anticyclones, has been carried out for a long time. Most weather phenomena remain a mystery.

Characterization of anticyclone

The anticyclone is understood the exact opposite of the cyclone. The latter, in turn, is a large whirlwind of atmospheric origin, which is characterized by low air pressure. Cyclone can form due to the rotation of our planet. Scientists argue that this atmospheric phenomenon is also observed on other celestial bodies. A distinctive feature of cyclones is the air masses moving counterclockwise in the northern hemisphere and clockwise within the south. Huge energy makes the air move with incredible power, in addition, strong precipitation, squalls, thunderstorms and other phenomena are inherent in this phenomenon.

In the area of ​​anticyclones, high pressure indicators are observed. The air masses in it move clockwise in the northern hemisphere and against the sentry within the south. Scientists have established that the atmospheric phenomenon favorably affects weather conditions. After passing the anticyclone in the region, moderate favorable weather is observed.

Two atmospheric phenomena have one general characteristic they can appear only in certain areas of our planet. For example, to meet anticyclone is more likely in the territories whose surface is covered with ice.

If cyclones occur due to the rotation of the planet, then anticyclones-with an excess of air mass in the cyclone. The speed of movement of air vortices ranges from 20 to 60 km/h. The dimensions of the cyclones are 300-5000 km in diameter, anticyclones-up to 4000 km.

Types of anticyclones

Air volumes concentrated in anticyclones move at high speed. Atmospheric pressure in them is distributed so that in the center it is as much as possible. The air moves from the middle of the vortex in all directions. At the same time, rapprochement and interaction with other air masses are excluded.

Anticyclones differ in the geographical area of ​​origin. Based on this, atmospheric phenomena are divided into entropical and subtropical.

In addition, anticyclones change in different sectors, therefore they are divided into:

  • The northern ones in the cold season there are small precipitation and continuous cloudiness, as well as fogs, in the summer cloudy;
  • Western ones-weak precipitation falls out in winter, layer-pouring clouds are observed, thunderstorms rattle in the summer and heap clouds develop;
  • South layered clouds, large pressure drops, strong winds and even snowstorms are characteristic;
  • Eastern these outskirts are characterized by storm rains, thunderstorms and heap clouds.
  • There are areas in which anticyclones are inactive and can be in this region for a long time. The area that an atmospheric phenomenon can occupy is sometimes equal to the whole continent. The possibility of repeating anticyclones is 2.5-3 times less than cyclones.

    Varieties of anticyclones

    Several types of anticyclones are distinguished:

  • Asian spreads on the territory of Asia; seasonal center of action of the atmosphere;
  • Arctic increased pressure that is observed in the Arctic; constant center of action of the atmosphere;
  • Antarctic concentrated in the field of Antarctica;
  • North American occupies the territory of the mainland North America;
  • Subtropical territory with high atmospheric pressure.
  • Also distinguish between highaltitude and sedentary anticyclone. Depending on the predominance of atmospheric phenomenon in certain countries, weather conditions are formed.
