摘要
对中国地面国际交换站安阳站的气候资料进行统计分析,得到了安阳地区气温和降水量的年际及季节变化的一些特征:安阳市年平均气温有增加的趋势,春季气温增幅最大;标准差及变差系数都是冬季较大,冬季气温变化比较剧烈;气温变化存在准20 a的波动周期;安阳市的年降水量有一个由增加到减少的波动变化。
The interannual and seasonal change characteristics of the air temperature and precipitation are gained by analyzing Anyang station data of China Surface International Exchange Station. The results show that the annual mean air temperature variation of Anyang is obvious increasing trend, especially in spring. The biggest standard deviation and variation coefficient in winter shows that the winter＇ s air temperature is severe. The variation of air temperature has a nearly 20 a fluctuating cycle. The annual precipitation is a variation from increasing trend to decreasing trend.
