In recent decades, India has witnessed an increase in the intensity, frequency, and spread of extreme weather events. The widespread increase in extreme precipitation over the Western Coast of India is a matter of great concern. The factors contributing to such devastating extreme precipitation remain unclear due to the variability present in meteorological and oceanic variables and associated large‐scale circulations. Using reanalysis and observed datasets, we attempted to identify a combination of dynamic, thermodynamic, and cloud microphysics processes contributing to the anomalous precipitation from August 1 to 10, 2019 against its climatology. Our key findings highlight the crucial role of warm sea surface temperatures (anomaly >1.4°C), outgoing longwave radiation (anomaly <−50 W·m−2), and atmospheric temperature (anomaly over the ocean is >1.6°C) in enhancing the moisture‐holding capacity of the atmosphere by almost 10%. This elevated moisture, propelled by intensified low‐level winds (anomalies exceeding 4 m·s−1), leads to a shift from ocean to land. Notably, we observe that vertical updrafts (anomalies >−0.4 m·s−1) contribute to increased atmospheric instability and moisture convergence. The presence of an ample amount of cloud hydrometeors, with anomalies surpassing 2.5 × 10−4 kg·kg−1, establishes conditions conducive to sustained intense precipitation. Our findings deepen our understanding of the complex relationships between ocean and atmospheric dynamics, and wind patterns, and emphasize their pivotal influence on regional weather patterns and land surface hydrology.

In the present work, a detailed examination of extreme rainfall events (EREs) has been carried out using weather research and forecasting (WRF) model and remotely sensed observations over the Northwest Himalayan region. We performed high-resolution model simulations and studied EREs in association with fine-resolution Indian National Satellite System (INSAT-3D) observations. Remarkable variations noted in the remotely sensed outgoing longwave radiation and rainfall in association with model simulations during the formation of cloudburst events may be utilized to give an alert over the locations potentially affected by the EREs. We found that the fine-scale structure of various physical quantities during the formation of the cloudburst events endures remarkable variations in close agreement with the satellite-based observations. Results obtained in the present study show a promising pathway for the study, analysis and now-casting of extremely heavy rainfall events based on model simulations in conjunction with remotely sensed observations.
