Summary
In this research, the focus is on examining the occurrence of localized Cloudburst events in the Indian Himalayan region (IHR). Specifically, in the year 2022, a total of 66 cloudburst cases were observed in the region, indicating a rise in the severity of extreme rainfall events (ERE) in recent times. Due to limited information and awareness, the mountainous hazards often go unnoticed. As the topographical feature has wider variation and because of the regional divergence there is also a variability in the intensity, duration and frequency of the EREs. Therefore, it is crucial to study the dynamics of the atmosphere during these events in order to enhance the understanding of researchers and facilitate the simulation of highly intense localized events in the future. Longitude-wise box (1ox1o ) was classified over the IHR in this research for a systematic analysis of the ERE dynamics. Furthermore, our study emphasized the statistical observational analysis of atmospheric dynamics in relation to observed rainfall across various boxes during the occurrence of the Cloudburst events. The temporal analysis is carried out by considering the atmospheric studies for the period starting 2 days before the event at the region. The relationship between major physical and thermodynamical atmospheric parameters and rainfall in different boxes has been comprehended and analysed. Understanding the intricate relationships between the atmosphere and land surface is crucial for making accurate predictions about the future. By delving into these complex interactions, researchers can gain valuable insights that can help improve forecasting models and enhance our understanding of the Earth's systems.
