摘要
利用2003年4月至2006年6月商丘太阳紫外线辐射强度资料及气象资料，分析了商丘市紫外线辐射的月、日变化规律及气象因子对紫外线辐射的影响。结果表明：商丘紫外线辐射月际分布是，年初、年底辐射量小，3-9月辐射量大，最大辐射指数为11．4；紫外线辐射的曰变化规律显著，基本上遵循正态分布，呈抛物线型变化，早晚辐射量小、中午前后紫外线辐射量大；紫外线辐射强度与总云量呈反相关，与能见度呈正相关，与气温呈正相关，与相对湿度呈反相关。
Basing on the ultraviolet radiation intensity and meteorological data during April, 2003 -June, 2006, the relationships between ultraviolet radiation and meteorological factors are analyzed. The intermonthly distribution of ultraviolet radiation shows a tendency of higher in the month from March to September is and lower in the other months of the year, and the maximum ultraviolet index is 11.4. The daily change curve of ultraviolet radiation is a normal distribution curve, which shows a tendency of higher at noon is and lower in the morning and evening. The ultraviolet radiation intensity is positive correlation with total cloud cover and relative humidity, but anticorrelation with visibility and temperature.
