Abstract

. In this paper the role of stability index (SI), mean relative humidity (MRH) from 00 and 12 GMT radiosonde ascents and dewpoint from 03 GMT synoptic observations of Lucknow for the period March to May 1985-88 has been examined.  The study reveals the SI value—4 or less, MRH 45% and above with dew point above normal are favourable for thunderstorm occurrence, Presence of large amplitude troughs in mid and upper tropospheric westerlies prove effective when these are around 70 oE.
