The relationship between vertical wind shear and the vertical extent of convective clouds is examined. In order to take into consideration the movement of the cloud, a ‘Relative Top Shear’ (RTS) is defined. Radar data and upper winds at some Indian stations in different seasons have been studied and a comparison made between RTS at different levels and the maximum tops of convective clouds. The results show that deep convective cloud was confined to layers in which RTS did not exceed 10 kt/km.
