Observation of Double-mixing Line Structure in the Convective Boundary Layer During the Summer Monsoon Season

Abstract

 — The special aerological observations carried out as a part of Land Surface Processes Experiment (LASPEX) were used to investigate the thermodynamic structure of the convective boundary layer during the summer monsoon of 1997. The analysis suggested that the convective boundary layer top was found at 700 hPa which was associated with θ e minimum and θ es maximum values. Double-mixing line structure was noticed in the conserved variable diagrams which was possibly attributed to the radiative warming/evaporation of falling precipitation.

Key words: Atmosphere, thermodynamic analysis, saturation point, convective boundary layer, summer monsoon.
