Heat content variability in the tropical Indian Ocean during second pre-INDOEX campaign (boreal winter 1996–1997)

Surface meteorological data and upper ocean temperature profiles are obtained on-board ORV Sagar Kanya (cruise 120) during the second pre-INDOEX Campaign (December 1996–January 1997) for evaluating the north–south variability of surface heat fluxes and upper oceanic heat content. Heat content in upp...

description Surface meteorological data and upper ocean temperature profiles are obtained on-board ORV Sagar Kanya (cruise 120) during the second pre-INDOEX Campaign (December 1996–January 1997) for evaluating the north–south variability of surface heat fluxes and upper oceanic heat content. Heat content in upper 200 m decreased southward by 50 × 108 Jm-2 along the ship's track. There is a net heat loss on either side of the equator with a marginal gain at the equator. In the vicinity of the Inter-Tropical Convergence Zone around 8°S where sea surface temperature is maximum, the heat content is conspicuously low, suggesting the divergence regime in the water column (0–200 m) due to a shear between southern equatorial and equatorial counter currents.
