Estimation of bulk transfer coefficient for latent heat flux (Ce)

Abstract

The bulk transfer coefficient for latent heat flux (Ce) has been estimated over the Arabian Sea from the moisture budget during the pre-monsoon season of 1988. The computations have been made over two regions (A: 0-8 degrees N: 60-68 degrees E: B: 0-4 degrees N: 56-60 degrees E) with the upper computational boundary fixed at the 300 mb level. The precipitation amount (P) was negligible for region A while the observed values of P have been used for region B. The Ce estimates have been compared with those obtained with other available schemes (Kondo, 1975: Bunker, 1976), which are based on wind speed and atmospheric stability within the surface layer. Value of Ce is higher in region A and lower in region B than the other estimates.
