摘要:
利用茂名市5个市县气象站1959-2015年逐日平均气温资料和日照资料,采用线性倾向估计、Morlet小波分析、相关分析等方法,对茂名市近60年低温阴雨区域平均时间序列进行统计分析。表明:茂名各市县低温阴雨天气频率呈西北向东南减少趋势,其日数和低温阴雨的年景分布相一致;茂名地区逐年平均低温阴雨日数序列整体呈下降趋势,平均气温则逐渐升高;茂名地区的低温阴雨日数存在3个显著周期振荡,其中6~7a的周期振荡和15a的周期振荡近60年始终存在。
Abstract:
Based on daily average temperature data and sunshine data from1959-2015 of weather stations in Maoming, the average time sequence of low temperature and overcast rain weather during nearly 60 years in Maoming were analyzed by linear trend estimation, Morlet wavelet analysis and correlation analysis methods. The results show that the frequency low temperature and overcast rain weather presented the reducing trend from northwest to the southeast, the distribution of days of this disaster is consistent with that of this disaster year; average cold rainy days sequence year by year has been experienced a decline as a whole while the average temperature is rising; there are three significant periodic oscillation of cold rainy days, in which the 6~7 a periodic oscillation and 15 a periodic oscillation exist all the time during nearly 60 years.
