摘　　要：应用锦州气象观测站日最高气温等常规观测资料,采用天气学和统计学方法,从气候特征、环流形势等方面对2004—2016年锦州高温天气过程进行分析,找出高温天气的预报着眼点,为高温天气预报预警提供参考依据。结果表明:锦州高温日数年份分布不均匀,年平均高温日为2.7 d;2004—2016年有3个明显多高温日的年份,分别是2004年、2009年和2015年。此外,高温日集中出现在4—8月,其中8月份高温日数最多,占总高温日数的46%,其次是6月和7月,分别占总高温日数的20%和27%。高温最早出现在4月26日,地点为锦州市区;最晚出现在8月17日,地点为锦州市区和北镇市。高温出现在14点和15点最多,占总日数的78%;锦州市区、义县高温日数较凌海、北镇以及黑山次数更多。持续2 d以上的高温日数集中在6月和8月,共有8次,最长持续时间为5 d。高温天气的环流形势可归纳为高压型、纬向环流型和副热带高压型。Based on the conventional observation data of meteorological observatory in Jinzhou,this paper analyzes the high temperature weather process in Jinzhou from 2004 to 2016 by statistical method from the aspects of climate characteristics and circulation situation,and finds out the focus of high temperature weather forecast.The results show that the distribution of high temperature days in Jinzhou area is uneven,with the annual average high temperature days being 2.7.There are three years with more high temperature days from 2004 to 2016,namely 2004,2009 and 2015.The high temperature sunrise is now from April to August,and the high temperature days are mainly concentrated in August,accounting for 46%of the total high temperature days,followed by June and July,accounting for20%and 27%of the total high temperature days respectively;The high temperature first appeared on April 26 th,in Jinzhou city,and the latest appeared on August 17 th,in Jinzhou city and Beizhen city.High temperature appeared at14 o’clock and 15 o’clock,accounting for 78%of the total number of days respectively;The number of high temperature days in Jinzhou city and Yixian county is obviously more than that in Linghai,Beizhen and Montenegro;The number of high temperature days lasting for more than two days appeared in June and August,with a total of 8 times and the longest duration was 5 days;The circulation situation of high temperature weather can be summarized as high pressure type,zonal circulation type and subtropical high pressure type Find out the forecast focus of high temperature weather,and provide reference for high temperature weather forecast and early warning.
