摘要/Abstract

摘要： 利用南寧氣象站1961—2009年太陽(yáng)輻射觀(guān)測資料，運用線(xiàn)性?xún)A向估計、M-K突變檢驗等方法對近49年來(lái)太陽(yáng)輻射變化的主要特征進(jìn)行了分析。結果表明，近49年來(lái)年太陽(yáng)總輻射呈弱下降趨勢，下降突變點(diǎn)為1964年，線(xiàn)性下降速率為28.9 (MJ/m²) /10a，其中下降主要發(fā)生在1961—1992年，1993年后顯著(zhù)增加；春、秋和冬季太陽(yáng)總輻射變化趨勢和全年相似，夏季則呈弱增加趨勢。分析表明，總云量和表征氣溶膠多少的能見(jiàn)度是影響太陽(yáng)總輻射變化的主要氣象因子。

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/m²per 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 decreased in spring, autumn and winter, especially in winter, while it increased weakly in summer. 3) The analysis results show that total cloud cover and visibility are the two important factors influencing the variations of global solar radiation in Nanning.
