Abstract

A tethersonde observational program was conducted for eight days during February and March 1989 at Pune, India, during daytime for the study of mixed-layer evolution. A surface-based nocturnal inversion of intensity 8-10 K (100 m)-1 was observed on most of the days. It takes about 2 h after sunrise for this inversion to start eroding and 4-5 h for complete erosion. Profiles of potential temperature, mixing ratio, and wind are discussed. Using Tenekes and Driedonks' convective boundary-layer model an average sensible heat flux of 129 W ,-2 is estimated during morning hours, which is comparable to the flux value obtained by an earlier study using an eddy correlation technique at a nearby site during March and April.
