| Zusammenfassung |
Air-Sea exchange of
momentum, heat and moisture over the oceanic surface plays an important role in
understanding several processes spanning various scales of atmospheric and
oceanic motions. The present study provides estimates of air-sea exchange
parameters along the cruise track of the Intensive Field Phase of Indian Ocean
Experiment (INDOEX, IFP-99) conducted on board Oceanic Research Vessel (ORV)
Sagar Kanya during 20 January–12 March 1999 for a large region of the Indian
Ocean. The study is aimed at acquiring a better understanding of the wind speed
dependence of air-sea interaction parameters, such as roughness lengths for
wind (z0), temperature (z0t) and hu-midity
(z0q), which play a key role in the determination of the
air-sea exchange coefficients and interface fluxes across the tropical oceans.
The variation of drag coefficient (CD), sensible heat and water
vapor exchange coefficients (CH and CE), are also
discussed in relation to the wind speed. An empirical relation is derived
between the estimated values of drag coefficients and the observed values of
wind speeds for the hitherto data-sparse regions over the tropical Indian
Ocean.
