Brief Description (Abstract):

During the month of February, the surface air temperature on an average remains subzero, but at times, it shows unusually high values. One such event was recorded during the first week of February 1996. In this, an attempt has been made to understand the dynamics of air and the physical processes through the observed data recorded by several PBL instruments operated at Maitri, Antarctica.

Status: Completed

Purpose: In the summer months, the surface air temperature recorded over Schirmacher region shows a diurnal variation of the order of 3- 4?C. This diurnal variation ceases during winter, as there is no surface heating due to long winter night (Naithani, 1995 Hosalikar and Machnurkar, 1998). However, the surface air temperature shows at times an enhancement of air temperature in winter. These enhancements are basically due to the hot, moist air pumped in by the prevailing cyclones over the ocean (Naithani, 1995). But, in summer months, enhancements are caused by the cyclonic winds as the coastline is much closer and by unusual phenomena which need detailed investigations. During February 1996, the surface air temperature went beyond 12 ?C, which is an unusual situation in the Schirmacher region as Table.l shows that in the past 7 years, temperature had never crossed 8.2 ?C.
