Wind - Simple English Wikipedia, the free encyclopedia

Wind can also be caused by the rising of hot air, or the falling of cool air. When hot air rises, it creates a low pressure underneath it, and air moves in to equalize the pressure. When cold air drops (because it is denser or heavier than warm air), it creates a high pressure, and flows out to even out the pressure with the low pressure around it.

Low-pressure area - Wikipedia

A low-pressure area, low, depression or cyclone is a region on the topographic map where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.

Brief note on the Formation of the Major Pressure Belts

The heated air is light and hence rises forming an area of low pressure. At 60 °N and 60 °S latitudes there is a sub-polar low pressure belt due to the descending of air from the polar region and the air from 30° North and South high pressure belts blows towards it, forming sub polar low- pressure belt above.

Atmospheric pressure - Wikipedia

The warm air is less dense and so it rises. This rising air over the land lowers the sea level pressure by about 0.2%. The cooler air above the sea, now with higher sea level pressure, flows towards the land into the lower pressure, creating a cooler breeze near the coast.
