Analysis of “0185” Heavy Rain in Shanghai

A process of heavy rain occurred in Shanghai on 5 and 6 August, 2001, the daily rainfall in the Huangpu and Xujiahui broke the record of last 50 years. Based on the densified satellite images, data of Doppler radar from Nanhui, Shanghai, the densified observation, and a dynamic diagnostic analysis of the event is documented. The result shows that it was the development of meso β-scale system that caused the heavy rain. And the deep humid neutral stratification and the symmetric instability, which act as the activator in the development of meso β
