The micro-structure of rain shower over Guang Zhou area in June of 1984

In this paper, the drop-size distribution of shower in Guangzhou has been analyzed. The results show that Type 3 spectra appeared with highest frequency and no Type 1 in that area.The average size is larger. The maximum diameter of drops can reach up to 0.5mm . The outstanding features are that the minimum diameter of drops is too large, and there are fc\v small drops but much more larger ones .As a re suit , it is imperfect to describe the spectra with an exponential function. Inaddition, the results reveal the areal difference of W-I relationship is much smaller than that of Z-I relationship. In Guangzhou area, W-I and Z-I relationship of shower are expressed respectively asZ=34511.39W=0.056910.88
