摘要:
为了进一步加强湖南省安仁县旱涝灾害防御以及降水的预报工作,使用1960-2013年安仁县降水量观测资料,采取回归分析、Z指数、小波分析等方法研究安仁县降水和旱涝变化特征。结果表明:1960-2013年安仁县年平均降水量为1444.3mm,年际变化较大;月尺度降水量分布呈现单峰型的态势,峰值出现在6月,4-6月为一年中降水最为集中的时段;从季节分布上看,主要集中在春季,其次是夏季,具有季节性、集中性的特点。安仁县容易产生干旱或雨涝,旱涝交替,其中旱年出现的频率比涝年高,严重干旱出现的频率比严重雨涝高。安仁县年降水量存在多重时间周期尺度上的嵌套结构现象,反映存在准2a、准7a、准12a和准23a的周期震荡。
Abstract:
Based on the precipitation data of Anren(1960-2013), change characteristics of precipitation and drought or flood were analyzed by regression analysis, z-index and wavelet analysis. The results show that during the period 1960-2013, the annual average precipitation of Anren is 1444.3mm with big interannual variation; the distribution of monthly precipitation presents a single peak with the maximum in the June and from April to June, it is the most concentrated period of precipitation in a year. Precipitation mainly concentrated in spring, followed by summer, it shows the seasonal and concentrative characteristics. Anren is prone to suffer from the drought or flood disaster, droughts and floods occur alternately, in which the the frequency of drought is higher than flood and the frequency of severe drought is higher than flood. It can be found that the annual precipitation in Anren has a nested structure phenomenon with multiple time scales by wavelet analysis method, and quasi-period is 2a、7a、12a、23a.
