摘要
通过探讨Z-I关系气候统计概率配对法和气候统计长沙雷达200km范围内4~6月汛期降水的Z-I关系,得出该区汛期降水是基本类似的,Z-I关系可用于该时空区域。将Z-I关系和ATi方法结合,进一步提高了单部雷达测量区域降水量的精度。这种方法不依赖地面自动雨量站网,增加了其实用价值。
Exploration is undertaken of the pairing of climatically statistical Z I probabilities and Z I relation based on April~June statistics over 200 km around Changsha. Evidence suggests that the rainfall pattern is broadly similar in the wet season and the obtained Z I relation is applicable to the study region; the relationship, when used with the ATi method, is able to further improve the measurement accuracy from a single radar set. Also, the technique is independent of a automatic surface rainfall measuring network.
