A numerical ocean model (CROCO) to study how sea surface height (SSH) changes in the Bay of Bengal during 2024. This variability is driven mainly by monsoon winds, river inflows, and ocean currents, and is important for climate, ecosystems, and coastal safety. The model simulation showed clear seasonal patterns: SSH is low and calm in winter, begins rising (especially northeast) in spring, peaks during the summer monsoon (June-September) with strong variations and heights exceeding 0.4 meters, and becomes more complex after the monsoon. The model successfully captured key features like coastal currents. Crucially, it revealed that SSH changes are tightly linked to the monsoon, with the biggest swings occurring along the western coast where massive freshwater from rivers meets the ocean, creating strong density differences. During the peak monsoon, the sea level difference across the entire bay can exceed 0.8 meters, driving powerful ocean currents. This simulation provides valuable new insights into the Bay's complex behavior for understanding ocean processes, checking satellite data, and improving seasonal forecasts.
