The atmospheric pressure is the weight of the air, which lies vertically above a unit area centered at a point. The weight of the air presses down the earth with the pressure of 1.034 gm / cm2. It is expressed in millibar () equal to 100 N/m2 or 1000 dynes/cm2. ... Sub polar low pressure belt (Southern hemisphere) (60° and 70°S) Polar high ...





Climate - Pressure, Wind, Air: Atmospheric pressure and wind are both significant controlling factors of Earth's weather and climate. Although these two physical variables may at first glance appear to be quite different, they are in fact closely related. Wind exists because of horizontal and vertical differences (gradients) in pressure, yielding a correspondence that often …





The air from high-pressure belts flows towards the low-pressure belts. This movement of air is called Planetary Winds. Temperature: The temperature difference between the equator and poles also affects Planetary Winds. The air near the equator is warm and the air near the poles is cold. The warm air rises and the cold air sinks.

















High pressure belts form as a result of air cooling and descending at specific latitudes in the Earth's atmosphere. As the air sinks, it becomes warmer and denser, creating an area of high pressure at the surface. These high pressure belts are typically found around 30 degrees north and south of the equator, known as the subtropical highs.







Continental air masses from eastern Europe have equally easy access westward. The almost continuous belt of mountains trending west-east across Europe also impedes the interchange of tropical and polar air masses. Air pressure belts. Patterns of some permanence controlling air mass circulation are created by belts of air pressure over five areas.











The Equatorial belt extends from 10° north to 10° south latitude.It is a thermally induced belt because here the temperature remains very high throughout the year due to the vertical sun's rays.The average pressure in this belt is less rhan 1013millibars,but in the eastern hemisphere it is generally less than 1009milibars.there is almost an absence of horizontal …
