| 摘 要： | 利用临汾市气象观测站1954—2018年气象观测资料,采用线性趋势估计、MannKendall检验等统计方法,对临汾市6种主要气象灾害的变化特征进行了研究。结果表明:暴雨、高温、雷暴主要发生在夏季,高发期均为7月,年平均发生日数分别为1.9、19.6、26.8 d;干旱、大风、雾在全年时段都有发生,干旱的高发期为秋冬季,春季为大风多发期,4月最多,雾多发生在秋冬季,11月为高发期,年平均日数分别为137.7、5.5、17.5 d。从气象灾害发生的年平均日数来看,依次为干旱>雷暴>高温>雾>大风>暴雨。近65年来,临汾市暴雨、干旱、雷暴、大风这4种气象灾害有减少趋势,其中雷暴、大风减少趋势明显,而高温、雾则明显增加。
