Abstract

By a study of hourly traces of PPI scope presentations on a Decca Type 41 Radar during premonsoon seasons of 1955-57, the directions of movement of thunderstorm sequences over Gangetic West Bengal were determined. Apart from the most predominant movement from NW/N, there were thunderstorms, which moved from even SE, S or SW, though such cases were rare. The wind direction in NW'ly squalls was generally same as the direction of movement of the squall lines though squalls from other directions were also recorded sometimes. Vertical currents in the thunderstorm cells were studied by scanning with radar at different elevation angles and some of the observations are presented.
