摘要:

通过对2005年1月至2007年12月石家庄市3 a来紫外线实况资料和地面常规观测资料的分析,发现紫外线强度与中午时段的能见度、相对湿度、总云量、低云量、气温、风速6个气象因子有密切关系,其中,它与总云量的关系最为密切,其次是相对湿度。紫外线与相对湿度、总云量、低云量为负相关;紫外线与风速、气温、能见度呈正相关,并且在不同的月份与气温的相关性有明显的变化。利用多元回归分析方法,得出紫外线等级预报方程,为紫外线的预报提供了指导意义。

Abstract:

Based on the data of solar ultraviolet radiation(UV)observed at Shijiazhuang and conventional meteorological observations rom January 2005 to December 2007,the relation between UV radiation and meteorological factors was analyzed.The results show that he UV radiation is closely related to the visibility,relative humidity,total cloud cover,low cloud cover,air temperature,wind speed t noon,especially the total cloud cover and the relative humidity.The UV radiation has negative correlation with relative humidity,total cloud cover,low cloud cover,and positive with air temperature,visibility,wind speed,and in diferrent months,the relation between UV and temperature presented obvious change.Using multiple regression analysis,the prediction equation of UV levels is established.It provided the guidance for the UV forecast.

Key words: ultraviolet radiation, meteorological factors, analysis, prediction equation
