摘要
利用1960-2018年黑河市6个国家气象观测站的观测资料对黑河市冰雹天气的分布特征进行研究。结果表明,1960-2018年黑河市累计发生冰雹554次,年平均降雹9.4次,1960-1982年年降雹次数较多,1982年以后降雹次数明显减少,近59 a减少速率为2.2次/a。黑河市冰雹多发生在白天(85.2%),夜间较少(14.8%)。黑河市冰雹的日变化表现为“单峰型”结构,11-12时和13-14时冰雹最多,分别为62和67次。冰雹最早在4月上旬开始(4月8日),最晚在11月上旬结束(11月6日)。冰雹主要集中在5-9月,占全年总数的91.3%,其中5月和6月冰雹最多,占全年的26.7%和25.6%。
Based on the observational data of six national meteorological stations in Heihe from 1961 to 2020,the distribution characteristics of hail weather in Heihe were studied.The results show that 554 hail events occurred in Heihe from 1960 to 2018,with an average annual hail of 9.4 times.There were many hailstorms from 1960 to 1982,and the number of hailstorms decreased significantly after 1982.The reduction rate in recent 59 years is 2.2 times per year.The hail mostly occurs in the daytime(85.2%)and less at night(14.8%).The diurnal variation of hail shows an"inverted U"structure,with the most hail at 11-12 o'clock(62 times)and 14-15 o'clock(67 times).Hail starts in early April(April 8)at the earliest and ends in early November(November 6)at the latest.Hail mainly concentrates from May to September,accounting for 91.3%of the total in the whole year,of which may and June have the most hail,accounting for 26.7%and 25.6%of the whole year.
