A monsoon is a seasonal weather pattern characterized by heavy rainfall and strong winds. It typically occurs in tropical and subtropical regions, significantly affecting the climate and agriculture. The most well-known monsoon is the South Asian monsoon, which brings vital rain to countries like India and Bangladesh during the summer months. Monsoons are caused by the differences in temperature between land and sea. In summer, the land heats up faster than the ocean, creating low pressure over the land. This draws in moist air from the ocean, resulting in heavy rains. Monsoons play a crucial role in replenishing water supplies and supporting crop growth.
