摘要
根据东阿县1962—2016年的降水气象资料,利用小波分析和气候倾斜率分析等数理统计的方法,对东阿县平均降水量、降水日数、降水强度和日最大降水量等指标进行分析。结果显示:55年来,东阿多年平均降水为600.2 mm;小波分析显示降水量和降水日数呈现出明显的周期性。
Based on the meteorological data of precipitation of Donga County from 1962 to 2016, the average precipitation, precipitation days,precipitation intensity and daily precipitation of Donga County were analyzed by wavelet analysis and climate slope analysis. The results showed that the annual average precipitation in Dong 'e was 600.2 mm in nearly 55 years. The wavelet analysis showed that the precipitation and precipitation days showed obvious periodicity.
