海口市太阳总辐射变化特征及其与气候因子的关系

Characteristics of Global Solar Radiation in Haikou and Relationships With Climatic Factors

利用海口地面站1971～2008年太阳总辐射和气象资料,对海口市太阳总辐射特征进行分析,结果表明:1971～2008年海口太阳总辐射以-248.467MJ/m2.a的速度减少,月变化与年变化趋势一致。低云量、水汽压是影响其太阳总辐射的主要气候因子。太阳总辐射与气温关系达到置信度为0.001的极显著水平。

The paper analyzed the variation charateristies of the global solar radiation in Haikou using sun bolometric radiation and the meteorological data from 1971 to 2008 which came from seaport ground station of Haikou.The results indicated that sun radiation reduced by- 248.467MJ/m^2·a, the month variation was consistent with the annual variation tendency.The low cloud amount and aqueous vapor tension were the main influencing factors.The significance of relationships between the global solar radiation and the temperature was remarkable at 0.001 level.
