It may be inferred from our study that higher moist convective instability coupled with enough moisture availability during the southwest monsoon season can increase the occurrence of deep convection. Hence the frequency of extreme rainfall events will also increase.
One of the most significant consequences of global warming due to increase in greenhouse gases would be an increase in magnitude and frequency of extreme precipitation events. These increased extreme precipitation events can be attributed to increase in moisture levels, thunderstorm activities and large scale storm activities. Physical considerations and model studies indicate that tropospheric warming leads to an enhancement of moisture content of the atmosphere and are associated with an increase in heavy rainfall events. Extreme rainfall results in...
