winter monsoon definition
A monsoon is a seasonal shift in the prevailing wind direction, that usually brings with it a different kind of weather. It almost always refers to the Asian monsoon, a large region extending from India to Southeast Asia where monsoon conditions prevail. During the winter monsoon, a persistent and large high pressure zone over Asia drives cool, dry air soutward toward the tropics. This provides the monsoon region with its dry season.
Quick Answer. The summer monsoon brings heavy rains and creates a moisture-rich atmosphere, while the winter monsoon generates long periods of dry and arid conditions. The summer monsoon generally begins in April and lasts through late September, while the winter monsoon arrives in October and ends in March.
