On the variation of temperature structure parameter in cloud- and clear-air during the summer monsoon season

High resolution aicraft observations of temperature were made in cloud-air and clear-air at different heights in the lower atmosphere over the Deccan Plateu, India, during the summer monsoon season (June-September) of 1976. Temperature fluctuations in the horizontal at each flight level were utilised for computing the temperature structure parameter (CT2) at that level for studying the hieght dependence of CT2. The results were found to be in agreement with those obtained by other investigators. Also, the height variations of CT2 in cloud-air and clear-air during active and weak monsoon conditions are studied. Marked differences were noticed in the behaviour of CT2 during active and weak monsoon conditions
