摘要
对近50年来肇州降水的集中度和集中期进行了计算分析,结果表明:近50年来,降水的集中程度有下降的趋势,集中期有提前的趋势。集中度和集中期分别存在着11a和14a左右的年代际尺度周期变化。肇州的年降水量呈下降趋势,肇州降水集中度和集中期与年降水量有很好的正相关性,年降水总量比较大的年份,降水集中程度相对较高。
in this article,the precipitation and the period of precipitation were analysed in recent 50 years in Zhaozhou county,the result showed that the mass precipitation was descending,and the period of mass precipitation was advancing tendency,and the mass precipitation and the period of mass precipitation showed the 11 years and 14 year＇s periodicity respectively.The annually precipitation in Zhaozhou expressed descending tendency,and also,between the mass precipitation 、the period mass precipitation and the annual precipitation expressed the positive interrelation,the more the annual precipitation,the more the mass precipitation!
