Unravelling the sources of moisture for precipitation events in a flood-prone Indian basin

Global warming has resulted in frequent occurrences of hydrological extremes, especially floods, across the globe. Flooding may lead to significant loss of life and economic damage. The increase in these flood events is due to the short intense rainfall events. Finding the geographical sources of the moisture that causes these short intense rainfall events is an important step toward predicting extreme events. The present research intends to investigate moisture sources for precipitation events over the flood-prone Indian Basin. Using the lagrangian moisture diagnostic, the research will look at moisture sources below the boundary layer as well as variations above the boundary layer from 1980 to 2018 during the Indian Summer Monsoon season. The study will also look at how the contribution from various sources varies over the course of the Indian Summer Monsoon Rainfall season. This work will enhance our understanding of the hydrological cycle and assist with a variety of related issues, including water resource planning, weather forecasting, land and water management, and more.
