Abstract

Abstract The seasonal variability of mixed layer depth (MLD) in the northern Indian Ocean (40°E – 105°E and 2°S – 30°N) was estimated from empirical relation using wind speed from QuickSCAT and wave parameters (significant wave height and wave period) obtained from MIKE-21 SW model. MLD estimated from this empirical model is compared with MLD estimated from Argo temperature and salinity profiles. The extent of mechanical mixing with in the top layer of water by local wind and wave activity is studied using this simple statistical predictive method. The correlation coefficient (R) between in-situ MLD and model MLD is found to be 0.52, 0.67, 0.34 and 0.04 for premonsoon, southwest monsoon, post-monsoon and northeast monsoon respectively. By and large, the proposed empirical model could be used to simulate the MLD and its trend by considering wind and wave parameters, and can act as a useful tool at times when there are sparse in-situ observations.
