The word monsoon comes from the arabic word ‘mausim’ which means season.
In the context of india, monsoon refers to indian-asian monsoon which brings heavy rains during the summer months over widespread areas of india and southeast asia. These rains often lead to major flooding. On the other hand, they are vital to agriculture and the economy. As a lot of the world’s population lives in this region, a delayed or reduced rainfall season can have a devastating effect on the livelihood of a significant fraction of the world’s population.
Indian monsoon blows from the northeast during cooler months and reverses direction to blow from the southwest during the warmest months of the year in order to bring about crucial rains in the month of june and july.
There are three distinct areas of relative upper tropospheric warmth like above the southern bay of bengal, above the plateau of tibet, and across the trunks of the various peninsulas which are relatively dry during this time. They combine to form a vast heat-source region and the relatively warm area above the southern bay of bengal occurs mostly at the level of 500–100-millibar.
