Abstract: Prediction of mixed layer depth (MLD) in the North Indian Ocean up to five days in advance was attempted using the one-dimensional numerical model of Price et al. [J. Geophys. Res. 91(1986) 8411-8427]. The model was first tested using the computed fluxes and profiles data from a moored buoy in the Arabian Sea. The forecast fields from National Centre for Medium Range Weather Forecasting (NCMRWF) were used for predicting MLD. MLD over the entire study area was computed by running the model on a 1º × 1º grid. The predicted MLD was compared with estimations from the in situ temperature profiles. Except at a few stations, where heat advection would have played a critical role in controlling mixed layer thermodynamics and thereby influencing the MLD, the RMS error was less than 10 m.
