| Abstract | Abstract Upwelling in the North Indian Ocean is a key driver of marine productivity and regional climate interactions, yet its long-term variability and underlying mechanisms remain underexamined. This study explores changes in upwelling patterns over the past three decades (1994⿿2024), using high-resolution reanalysis datasets (ERA5, ORAS5, HERMES) along with key oceanic and atmospheric variables such as sea surface and subsurface temperature, sea level anomaly, wind, and chlorophyll-a. A multi-parameter approach is applied to identify upwelling zones and track their evolution through vertical temperature structure and surface signals. The role of the Indian Ocean Dipole (IOD), captured via the Dipole Mode Index (DMI), is also investigated to assess its potential influence on these changes. Preliminary results suggest emerging spatial patterns and seasonality shifts, hinting at a more complex coupling between ocean dynamics and climate variability than previously recognized. These findings offer new perspectives on the sensitivity of Indian Ocean upwelling systems to a changing climate. |
