摘要
分析了广州地区从化测站１９９４年６月份的雨滴谱资料，发现造成华南特大洪涝灾害的６月份降水的特点是：降水时间长，雨强、雨滴浓度、尺度均较大，最大雨滴直径为６．５ｍｍ，最大雨强为１５５．０６ｍｍ／ｈ。另外，按天气系统、降水性质综合考虑分类，把降水分成５大类，提供了一组可供雷达定量测量降水时参考和应用的Ｚ－Ｉ关系。
In this paper, the raindrop data collected at Conghua station in Guangzhou area in June 1994 have been analyzed. It is found that the June rainfall doing great flooding damage has some features: raining time. rainfall intensity, raindrop density and scale are also larger. The largest raindrop diameter and rainfall intensity are 6.5mm and 155. 06mm/h respectively. On the other hand, according to weather system and rainfall feature, we divided rainfall into five types and provided a group of Z-I relationship that can be referenced and used in radar quantitative measurement of rainfall.
