摘要
[目的]分析广西太阳辐射分布特征及与气象要素的关系。[方法]利用1995~2009年广西太阳辐射站的观测资料,分析广西太阳辐射站总辐射、日照分布特征及年际变化;并利用南宁站的观测资料,分析南宁净辐射年、季、月变化特征及南宁总辐射与低云量、地温等要素的线性关系。[结果]广西太阳总辐射量低纬度大于高纬度,表现为北海>南宁>桂林;不同地区太阳辐射的变化幅度和季节变化存在明显差异,表现为自北向南逐步增大,夏季>秋季>春季>冬季,且总辐射和日照时数变化趋势基本一致;太阳总辐射与低云量的关系为负相关,与少云的晴天天气为正相关,太阳总辐射除冬季外与地面温度呈正相关。[结论]该研究为广西气候研究及太阳能资源的开发利用提供有效的理论依据及数据参考。
[Objective] To analyze the relationship between solar radiation distribution characteristics and meteorology elements in Guangxi.[Method] By using observation data during 1995-2009,total solar radiation,sunshine distribution characteristics and annual variation of Guangxi were analyzed.Using observation data of Nanning Station,annual,seasonal and monthly variation characteristics of net radiation were analyzed,as well as linear relationship between total radiation and low cloud amount,ground temperature.[Result] Total solar radiation in low latitude of Guangxi is higher than in high latitude,the order is Beihai Nanning Guilin;the variation amplitude of solar radiation in different region has significant difference with seasonal variation,indicating increase from north to south,summer autumn spring winter,and total radiation is accordance with variation trend of sunshine hours.Total solar radiation has negative correlation with low cloud amount,positive correlation with sunny day and ground temperature.[Conclusion] The study will provide effective theoretical basis and data reference for climate research and solar resource development and utilization in Guangxi.
