| 摘 要： | 利用南宁气象站1961-2009年太阳辐射观测资料,运用线性倾向估计、M-K突变检验等方法对近49年来太阳辐射变化的主要特征进行了分析.结果表明,近49年来年太阳总辐射呈弱下降趋势,下降突变点为1964年,线性下降速率为28.9(MJ/m2)/10a,其中下降主要发生在1961-1992年,1993年后显著增加;春、秋...

| Abstract: | Based on the solar radiation observation data in Nanning from 1961 to 2009,the characteristics of solar radiation change for recent 49 years were investigated,by using the linear-trend estimate and the Mann-Kendall test.The results show that:1) The global solar radiation overally showed a weakly decreasing tendency over the 49 years at a rate of 28.9 MJ/m2 per 10 years,with a main decreasing trend in the period 1961-1992,while an obvious increasing trend after 1993.2) The global solar radiation generally de... |
