Question

Give a reason why cyclonic rainfall is common in the belt of the Westerlies.

Answer 1

Cyclonic rainfall is common in the belt of the Westerlies because this region lies between the subtropical high-pressure belt and the subpolar low-pressure belt (between 30° and 60° latitudes). Here, warm tropical air meets cold polar air, leading to the formation of mid-latitude cyclones or depressions. These cyclones cause the warm air to rise over the cold air, resulting in condensation and cyclonic rainfall. The Westerlies, being strong and prevailing winds in this belt, bring moisture-laden air that facilitates the development of cyclonic storms, making cyclonic rainfall frequent in this region.
