Wind currents and monsoon
As we know that the wind flows from the area of high pressure regions to low pressure regions. Following are the reasons which causes the formation of wind currents.
1. Uneven heating between the equator and poles result in a large wind current which set up from poles towards the equator
2. Uneven heating of land and water during the day and night gives rise to the sea and land breeze respectively.
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.
