摘　　要：文章基于2021年影响舟山的两次重要台风过程,将面雨量、定海国家基本气象站降雨量和城北水库周边自动气象站降雨量作为水库降雨量值,分析了城北水库溢洪前的蓄水量和溢洪后的溢洪量。研究得出,2021年影响舟山的两次重要台风过程有极高的研究价值;将定海国家基本气象站的降水量作为主要参考数据,有较明显的实际应用优势;每1 mm降水量可以造成城北水库约5000 m~3的水库溢洪量/水库蓄水量。研究得出的预报方程可为定海区城北水库溢洪时间、溢洪量等要素的预报提供参考依据。Based on the two important typhoon processes affecting Zhoushan in 2021,using the surface rainfall,the rainfall of Dinghai National Basic Meteorological Station and the rainfall of automatic meteorological station around Chengbei Reservoir as reservoir rainfall values,this paper analyzes the water storage capacity and overeflow capacity of Chengbei Reservoir.It is concluded that the two important typhoon processes affecting Zhoushan in 2021 have high research value.Taking the precipitation of Dinghai National Basic Meteorological Station as the main reference data has obvious practical application advantages.Every 1 mm precipitation can cause about 5000 m~3 of reservoir flood overflow/storage in Chengbei Reservoir.The prediction equations obtained from the study can provide a reference for the predicting factors such as overflow time and overflow volume of Chengbei Reservoir in Dinghai District.
