Air-sea interface fluxes over the Indian Ocean during INDOEX, IFP-99

Abstract

The Intensive Field Phase of Indian Ocean Experiment (INDOEX, IFP-99) was carried onboard Oceanic Research Vessel Sagar Kanya during January 20-March 12, 1999 over the latitudinal range 15°N-20°S and the longitudinal range 63°E-77°E. The present study deals with the spatial variation of air-sea fluxes over the Indian Ocean during the INDOEX, IFP-99 campaign. Drag coefficient (CD), and sensible heat (CH) and water vapor (CE) exchange coefficients are determined using an iterative scheme. The estimated values of these coefficients are utilized for the computation of air-sea fluxes using the bulk aerodynamic method. The variations of air-sea flux estimates are studied with respect to the variation of wind speed. © 2002 Elsevier Science Ltd. All rights reserved.
