Implication

Observational and hydrological modeling reveals extreme multi-day monsoon rainfall and soil saturation drive major regional floods, highlighting escalating disaster risks under climate change.

Key Points

To identify the atmospheric mechanisms, moisture sources, and soil moisture conditions that drove catastrophic flooding during the 2024 summer monsoon.
Analyzed extreme rainfall events across western, southern, and northern flood-affected zones using observational meteorological records and atmospheric reanalysis datasets.
Simulated catchment runoff and tracked atmospheric moisture pathways using hydrological models and moisture transport analyses.
The 3-day extreme precipitation events generated floods with estimated return periods exceeding 75 years in western regions, 100 years in southern regions, and 200 years in northern regions.
Pre-existing multiday precipitation created saturated soil conditions that minimized infiltration and triggered massive surface runoff during subsequent extreme downpours.
Flooding was driven by distinct moisture transport pathways, including influxes from the Arabian Sea, the Bay of Bengal, and recycled continental land moisture.
