摘要
采用河北省人工影响天气办公室研究的增水计算方法,对秦皇岛市的桃林口水库、洋河水库两大水库的水系流域在历年日最大降水(包括水文站、气象哨资料)条件下,如果进行人工增雨作业,可能增加的最大水量进行评估。结果表明,在汛期(6-9月)进行增雨作业不会给两大水库带来风险。根据气候变化分析认为,以增加水库蓄水为目的的人工增雨作业,最有效的办法是在汛期进行人工增雨作业。在汛期到来时,抓住一切有利天气连续作业,才能达到增加蓄水的目的。
The risk evaluation of precipitation enhancement in flooding season over the reservoir area in Qinhuangdao is conducted by using the method for computing the increased precipitation developed by the Weather Modification Office of Hebei Province, based on the precipitation data of the area around two big reservoirs of Qinhuangdao, in case of the largest rainfall in history over the Yanghe and Taolinkou drainage areas resulted from precipitation enhancement operation. The result shows that precipitation enhancement operation will not cause danger to reservoirs. According to the analysis of climate change, the precipitation enhancement aiming to increase the water capacity of reservoirs in flooding season is an effective approach.
