摘要:
根据江苏省1951—2020年的月降水资料，采用Mann-Kendall 检验、滑动T检验和小波分析等方法，对江苏省主汛期（6—9月）降水的趋势性、突变点与周期性进行分析。研究表明江苏省不同城市按月降水量的峰值特征可分为3类，各区域主汛期月平均降水量年际上呈现增长趋势，但变化趋势并不显著；各区域主汛期月平均降水量在2013年前后发生较为明显的变异，变异后的降水量呈增加趋势；各区域主汛期月平均降水量具有较为相似的周期变化过程，第1主周期均为13 a左右。
Abstract:
Based on the monthly precipitation data of Jiangsu Province from 1951 to 2020, this paper uses Mann-Kendall test, sliding t test and wavelet analysis to analyze the trend, mutation point and periodicity of precipitation in the main flood season （June-September） of Jiangsu Province. The results show that the peak characteristics of monthly precipitation in different cities of Jiangsu Province can be divided into three categories. The monthly average precipitation in the main flood season of each region shows an increasing trend, but the trend is not significant. The monthly average precipitation in the main flood season of each region had obvious variation around 2013, and the precipitation increased after variation. The monthly average precipitation in the main flood season of each region has a similar periodic variation process, and the first main cycle is about 13 years.
