摘要
采用20年热带气旋资料分析统计了影响闽西地区的热带气旋降水气候状况.依路径将影响闽西的热带气旋分三个影响型,降水则区分强降水、一般降水和无雨3档,受影响的闽西(龙岩市)区分三个片。主要分析统计各热带气旋影响型与闽西降水的关系,降水与热带气旋活动位置的关系。结果表明。西太平洋型是闽西热带气旋强降水的主型,也是预报预防热带气旋降水灾害的重点类型;强降水时,热带气旋位置有明显的集中区:西——南——陆型热带气旋是闽西热带气旋一般降水的主型,多有益性降水。
Based on 20 years data, We analysis and count the Typhoon rainfall conditions in Minxi district, Fujian.
