In addition to above,the monthly mean data of number of thunderstorm days(Tin), number of rainy days (TM), rainfall amount in mm(Ta), ratio of T and Tiff and ratio of Tff and Tb, have beencomputed and results are presented for different seasons(Pre-monsoon, monsoon, post monsoon and winter) forthe period December 2000 to November 2006. Theexistence of convective regime during monsoon is veryimportant for deciding the performance of southwestmonsoon. 收起
