Description 194-197
Short time variability in the temperature field at two stations off Calicut was analysed. Lower diurnal range of temperature was noticed in the surface layers at the shallow station (0.4-degrees-C) than at the deep station (0.8-degrees-C). This feature was explained based on surface heat exchanges, eddy diffusivity and Monin-Obukhov length. Monin-Obukhov length revealed the dominance of buoyant mixing over mechanical mixing at both the stations. Greater turbulence within the mixed layer at the shallow station (93 cm2. sec-1) than at deep station (78 cm2. sec-1) as revealed by the coefficient of eddy diffusivity reduced the amplitude of surface temperature at the shallow station. Two layers of thermal inversions were observed at the deep station while at the shallow station these two layers merged to form a single inversion layer. It is concluded that these thermal inversions are caused by the intrusion of the Arabian Sea High Salinity Watermass.
