摘要
文章利用呼和浩特市气象局逐月雷暴日数及年雷暴初日、终日资料,选择线性倾向估计法和滑动平均法对呼和浩特雷电活动特征进行分析,并探讨雷电防御对策。结果表明:呼和浩特年内雷暴日数呈现单峰型变化特征,尤以夏季出现频率最高,其次是秋季,春季雷暴天气出现频率相对较低。为了降低雷电造成的危害,应做好雷电防御工作。
In this paper,the monthly thunderstorm days and annual thunderstorm beginning and ending days of Hohhot Meteorological Bureau are used to analyze the characteristics of lightning activities in Hohhot by using the linear trend estimation method and the moving average method,and the countermeasures for lightning prevention are discussed.The results show that the number of thunderstorm days in Hohhot shows a unimodal variation,with the highest frequency occurring in summer,followed by autumn,and the relatively low frequency of thunderstorm weather in spring.In order to reduce the harm caused by lightning,lightning prevention work should be done well.
