Abstract

Convection and rainfall association is very old and sounding of the atmosphere either remote sensing or conventional methods can help to know the possibility of it. In this article author describes the brief about the various thermodynamic indices by conventional methods and utility of other tools like T-Phi gram to measure the convective instability in the atmosphere. The Convective Available Potential Energy (CAPE) and Convective Inhibition Energy (CINE) of the year 2002 and 2006 obtained from radiosonde data (0000 and 1200 UTC) for Delhi and Chennai. The contrasting behavior of the South West Monsoon season with the help of CAPE and CINE is also highlighted.
