The ITCZ is the belt of low pressure near the equator where the trade winds meet. It is not fixed; it moves North during the Northern Hemisphere summer and South during the Southern Hemisphere summer. This “migration” of the ITCZ ...

The Chinook is classified as a local wind because it is specific to a particular geographic region—the Rocky Mountains in North America. Unlike “prevailing” or “permanent” winds that blow across the entire globe (like the Trade Winds), the Chinook only ...
The Pampero is a cold, dry wind that blows across the Pampas, the vast grassy plains of Argentina and Uruguay. It originates from the cold polar regions and usually follows the passage of a cold front. These winds bring a ...
During the summer months, the subtropical high-pressure belt shifts northward. This causes the trade winds (specifically the Northeast Trades) to blow from the high-pressure regions of the horse latitudes toward the Mediterranean basin. These winds are generally dry, contributing to ...
The height of the troposphere increases during the summer season. This occurs because higher temperatures cause the air near the surface to expand and rise more vigorously. The resulting increase in thermal energy pushes the tropopause—the boundary between the troposphere ...
