| 摘 要： | 利用大连市2007年8月至2008年8月逐日紫外线观测资料，分析了紫外线辐射季、月和日变化特征及其与相关气象要素的关系。结果表明：大连市紫外线辐射强度具有明显的季节变化，夏季最大，春季次之，冬季最小。各季节紫外线辐射强度的日变化同位相，均为正午呈大致对称分布。无论何季节，日照总时数、14时能见度和太阳高度角均为影响大连市紫外线辐射强度的关键因素。同时，详细分析了雾对辐射强度的影响。并运用逐步回归方法，求得各季节紫外线辐射强度的预报方程，实现了预报的定量化。

| Abstract: | Based on the ultraviolet radiation observation data from August 2007 to August 2008 in Dalian,the seasonal,monthly and daily changes of ultraviolet radiation and the relationships with meteorological factors were analyzed.The results show that the ultraviolet radiation intensity is of seasonal characteristic in Dalian,which is strong in summer,followed in spring and winter.The diurnal variation has the same trend among different seasons,which is an approximately symmetric distribution at noon.The total suns... |
