Frontal rainfall occurs when a warm air mass meets a cold air mass, a process central to “Extratropical” cyclonic activity. In this interaction, the lighter warm air is forced to rise over the denser cold air. As the warm air ...

Trade winds are caused by the convection of heat on a global scale. At the equator, the intense sun heats the air, causing it to rise. As this air moves up, cooler air from the subtropics flows in along the ...
The Horse Latitudes (30° N/S) are regions of high pressure created by sinking air. As air rises at the Equator, it travels poleward and eventually cools, becoming dense enough to sink back to Earth at these latitudes. Sinking air compresses ...
The Chinook is nicknamed the “snow eater” because of its incredible power to melt snow in North America. These warm, dry winds can raise the temperature by 20 degrees Celsius in just a few hours. This rapid heat causes snow ...
The Furious Fifties are strong westerly winds located at 50° South latitude. They are part of the same system as the Roaring Forties but are generally more intense. As you move closer to the cold Antarctic region, the temperature difference ...
