摘要:

通过对张掖市2005~2006年紫外线强度监测资料综合分析,得出张掖市紫外线辐射3级强度以上占全年的58. 8% ,属于紫外线辐射高强度地区,对人体影响很大。日最大值出现在12: 00~14: 30时段,年以6~9月为最强。各季节紫外线变化以夏秋2季波动较大,主要是因为该季节天气现象复杂。统计分析发现,云量的多少对紫外线的辐射强度影响很大,当全天或11: 00~16: 00时段内云量达到6成以上时,紫外线强度均在2级以下。

Abstract:

By analyzing the solar ultraviolet observation data of Zhangye in the years of 2005 and 2006, we can make a conclusion that the ultraviolet radiation over Zhangye is very high, and the intensity of the solar ultraviolet above three - degree is account for 58. 8% in a year. The maximum value of the solar ultraviolet appeared between 12: 00 am and 14: 30 pm in a day and from June to Sep tember in a year. Due to the comp lex weather phenomena, the solar ultraviolet in summer and autumn was fluctuant frequently. According to the statistics, cloud amount has very obvious influence on solar radiation, when the cloud amount getsmore than six - tenths in a day or at the time of 11: 00 - 16: 00, the ultraviolet radiation intensity will be under the two - degree.

Key words: ultraviolet radiation intensity, characteristic, Zhangye
