| 摘 要： | 利用水文站1960—2018年雨量观测资料和台风资料,分析了影响新昌台风的降雨时空变化特征。结果表明,近58年来影响新昌台风个数呈增加趋势,从1960—1969年15个增加到2010—2018年26个;在5—10月均有台风影响新昌,7、8、9月是台风影响新昌的主要月份,分别达22、49、32个;新昌东南部是台风影响过程降雨最严重的地区,台风影响过程最大降雨量可达500 mm以上;在福建北部到浙江南部登陆的台风出现过程雨量200 mm以上的大暴雨概率最大,东部地区可达35%以上。该研究可为提高防灾减灾精细化管理提供技术支撑。

| Abstract: | Based on the rainfall observation data and typhoon data of hydrological station from 1960 to 2018,the temporal and spatial variation characteristics of rainfall affecting Xinchang typhoon were analyzed.The results showed that the number of typhoons affecting Xinchang had increased from 15 during 1960-1969 to 26 during 2010-2018 in recent 58 years.From May to October,there were typhoons affecting Xinchang,with the most typhoons in July,August and September.The southeast of Xinchang was the area with the most severe rainfall in the process of typhoon,and the maximum rainfall in the process of typhoon could reach more than 500 mm.In the process of typhoon landing from the north of Fujian to the south of Zhejiang,the probability of heavy rain with rainfall over 200 mm was the highest,and the probability of heavy rain in the East was over 35%.This research could provide technical support for improving the fine management of disaster prevention and mitigation. |
