<p>The dynamics in the Northwestern Indian Ocean (NWIO) is governed by mesoscale processes that modulate spatio-temporal variations in sea surfac temperature (SST), sea surface salinity (SSS), and mixed layer depth (MLD), while also impacting turbulent energy transfer. The seasonal variations in energetics impacts the air-sea interaction and moisture transport across NWIO, which is crucial for Indian subcontinent. Thus, improvement in vertical mixing models to predict ocean state close to observation is essential. The aim of this study is to model spatio-temporal variation of energetics using eddy kinetic energy (EKE) budget terms, namely, shear production, buoyancy production, and dissipation. Model produced surface currents, SST, SSS, and MLD exhibit a good agreement with climatology for all seasons. Analysis of energetics reveals that EKE is confined to western Arabian Sea and in equatorial regions. In western Arabian Sea, during winter (December to February), negative shear production, which is a strong indicator of inverse energy cascade is balanced by buoyancy production of EKE. This shows that energy is primarily produced by unstable water column. Similarly, in equatorial region during October–November, energy production is dominated by buoyancy and inverse energy cascades. During summer monsoon (June to September), both shear and buoyancy production dominate along Somalia coast. In regions where inverse cascade is present, dissipation is weak. When both buoyancy and shear production aid in energy generation, strong dissipation is observed, while weak dissipation under such circumstances indicate energy transport between different regions. Overall, the eddy energetics provide a clear pathway for improving the efficacy of mesoscale parameterization in regional models.</p>
