1769-1773In this study the variation of bulk-skin temperature (∆T) during May-June, has been studied using different methods proposed earlier. To our knowledge, this aspect has not been studied so far for the Arabian Sea or Bay of Bengal. The earlier methods failed to reproduce the variation of ∆T in this region during the period of observations. The following relations are proposed to estimate non-dimensional numerical coefficient λ and skin-bulk temperature variation (∆T).
λ = 1.37*U+9.8 (for the wind speed, 2-8 m/sec)
∆T= -0.026*Q/U +0.089
Where Q is the sum of latent, sensible and net long wave radiation and U is the wind speed (m/sec). The newly proposed relations are compared with the previously proposed and found that newly developed relation is suitable for Arabian Sea especially for the night time. Root mean Square (RMS) errors (0.2° C) are indicating the performance of newly proposed relations
