| Summary: | <p>Convective available potential energy (CAPE) is a measure of the amount of
energy available for convection in the atmosphere. The satellite-derived data
over the ocean and land are used for a better understanding of the atmospheric
stability indices. In this work, an attempt is made for the first time to
estimate CAPE from high spatial and temporal resolution measurements of the
INSAT-3D over the Indian region. The estimated CAPE from the INSAT-3D is
comprehensively evaluated using radiosonde derived CAPE and ERA-Interim CAPE.
The evaluation shows that the INSAT-3D CAPE reasonably correlated with the
radiosonde derived CAPE; however, the magnitude of CAPE shows higher values.
Further, the distribution of CAPE is studied for different instability
conditions (different range of CAPE values) during different seasons over the
Indian region. In addition, the diurnal and seasonal variability in CAPE is
also investigated at different geographical locations to understand the
spatial variability with respect to different terrains.</p> |
