摘要
2008年“5.12”特大地震给北川羌族自治县造成重大损失,北川国家一般气象站由曲山镇茅坝村站址(简称旧站)搬迁至30km外永昌镇站址(简称新站)。本文利用新站2011~2018年观测资料与旧站1981~2010年观测资料,通过差值统计方法,对新站的整编资料与旧站的整编资料进行对比分析,结果表明:新站平均气温偏高0.7℃,极端最低气温偏高,极端最高气温偏低;年日照时数偏多139.3h,2min平均风速偏大0.5m/s,极端最大风速偏大;年降水量偏少29.5mm,风向相差90°左右,差异较大。
The 5.12 earthquake in 2008 caused great losses to Beichuan Qiang Autonomous County,the national general weather station in Beichuan was moved from Maoba Village Station in Qushan Town(referred to as the old station)to Yongchang Town Station 30km away(referred to as the new station).The compilation data of the new station from 2011 to 2018 and the compilation data of the old station from 1981 to 2010 are used to compare and analyze with the difference statistical method.The results show that in the new station,the average temperature is 0.7℃ higher,the extreme minimum temperature is higher,and the extreme maximum temperature is lower.Meanwhile,the annual sunshine hours is 139.3h more,the 2min average wind speed is 0.5m/s larger,the extreme maximum wind speed is larger,the annual precipitation is 29.5mm less,and the wind direction is about 90°,which is quite different.
