Abstract:
In this paper, the raindrop spectral data collected at the Conghua station in Guangzhou area in June 1994 have been analyzed.It is found that the June rainfall causing great floods damage in southern China has the following features: It has long duration, large intensity, raindrop density and scale, with the largest raindrop diameter and rainfall intensity at 6.5 mm and 155.06 mm/hr respectively.on the other hand, according to weather system and rainfall nature, we divided the rainfall into five types and provided a group of Z-I relationships that can be referenced and used in radar quantitative measurement of rainfall.
