摘要
利用海南省2012~2014年紫外线资料,对比分析沿海和陆地紫外线。结果表明:晴好天气下,沿海紫外线日极值比陆地高3~11 W/m2。沿海紫外线辐射月平均值比陆地高0.67-17.07 W/m2。沿海紫外线辐射年平均值比陆地高4.87~13.51 W/m2。沿海紫外线超过四级的天数比陆地多294天。沿海气温、能见度比陆地高,相对湿度、总云量、降水量比陆地低。两者气温、相对湿度、能见度差异较大,影响紫外线比较明显;总云量、降水量差异较小,影响紫外线相对较弱。
Based on the ultraviolet observations from 2012 to 2014 in Hainan Province,the coastal ultraviolet and inland ultraviolet are compared and analyzed.The results show that the daily maximum value of coastal ultraviolet is 3-11 W/m2 higher than the inland ultraviolet.The monthly average value of coastal UV is 0.67-17.07 W/m2 higher than the monthly average value of inland UV.The annual average value of coastal UV is 4.87~13.51 W/m2 higher than the monthly average value of inland UV.The number of ultraviolet rays in the coastal area over four is 294 days more than that of the land.The coastal temperature and visibility are higher than those on land,while relative humidity,total cloud,and precipitation are lower than those of land.The difference of temperature,relative humidity and visibility between them is quite different,and the influence of ultraviolet is obvious.The difference between total cloud amount and precipitation is relatively small,and the influence of ultraviolet is relatively weak.
