Creates basically a wind mode. With the transfer of air masses by general circulation, the global transfer of heat and moisture is associated. The existence of atmospheric circulation is due to the non-uniform distribution of atmospheric pressure, caused by the influence of uneven heating of the earth's surface at different latitudes, as well as over continents and oceans [1].

Air masses freely move and exchange in the troposphere and lower stratosphere up to the upper boundary of the geographical envelope (approximately 20 km).

The uneven distribution of heat in the atmosphere leads to an uneven distribution of atmospheric pressure, and the movement of air, or air currents, depends on the distribution of pressure.

The nature of the movement of air relative to the earth's surface is importantly influenced by the fact that this movement occurs on a rotating Earth. In the lower atmosphere, air movement is also affected by friction. The movement of air relative to the earth's surface is called the wind, the entire system of air currents on Earth is called the general circulation of the atmosphere. Vortexes of a large scale - cyclones and anticyclones, constantly arising in the atmosphere, make this system especially complex.

The main changes in the weather are associated with the movement of air in the process of general circulation: air masses, moving from one area of ​​the Earth to another, bring with them new conditions of temperature, humidity, cloudiness, etc.

In addition to the general circulation of the atmosphere, there are local circulations: breezes, mountain-valley winds, etc.; there are also strong whirlwinds of a small scale - tornadoes, blood clots.

The wind causes waves of water surfaces, many ocean currents, drift
