| Abstract: | A few case studies of severe thunderstorms especially hail storms, over
Chennai and its neighbourhood within 250 km radius that occurred during 2002-2007
have been analysed in this paper. Pre-convective thermodynamic parameters have
been computed using Chennai, Karaikal, Bangalore,
Machilipatnam and Hyderabad RS/RW data; and empirical thresholds that are in
vogue have been validated for the hail storms reported by print and electronic
media. Hail stone size estimation has been attempted using build 9 algorithm of
NEXRAD, USA and found to be working well
for the tropical environment as well. The necessity of feedback from the public
in timely reporting severe storms with precision and accuracy has been stressed
for developing a database to fine tune the hail warning and hail stone size
estimation algorithms. |
