Abstract:
This thesis is the result of an elaborate study on
the mixed layer depth (MLD) and the various oceanic
environmental factors controlling it in the Arabian Sea
examining its predictability on annual and short term basis.
To accomplish this, the study area between 100 — 250 N
latitudes and 600 — 750 E longitudes in the Arabian Sea
is divided into 8 subareas of 50 quadrangles. The
distribution of monthly means of the surface wind field, net
heat exchange mKi868€%WTmN¥tWMWF3UH9 (SST) over each subarea
in the annual cycle is examined. The corresponding wind
(mechanical) and convective mixing values are computed and
presented along with the observed mean MLD for the subareas
in the annual cycle. Effects of advection due to surface
currents and surface divergence (convergence and divergence)
for these subareas are examined for correlating the MLD
variations. A representative time series data from typical
deep water station under southwest monsoonal forcing is
analysed for the spectral components to estimate the
amplitude perturbations on the mean MLD variation
