| Abstract: | This is a case study of the environmental wind fields in a local severe convective storm occurred on 25 March 1983 in the Zhujiang River delta area of South China . Some aspects of the wind fields such as structures and variations of the upper tropospheric WSW jets , divergent wind fields and the related vertical secondary circulations , and the vertical and horizontal wind shear etc. were examined in relation to the severe convective weather process with operational observations . |
