| 摘 要： | 利用乌鲁木齐市气象站1976—2005年太阳辐射和气象观测资料,分析乌鲁木齐市太阳辐射的变化及其成因。结果是:1990年以前总辐射、直接辐射是减少的,以后是增加的;而散射辐射在1986年之前递增、之后递减。初步认定总云量的减少、低云量的增加以及相对湿度的缓慢下降对太阳辐射变化有重要影响;从太阳辐射变化间接得出:近30a乌鲁木齐市空气污染总体有所减轻。

| Abstract: | Using the data of solar radiation and meteorology observation of Urumqi meteorology station between 1976-2005,the variation of the solar radiation and its cause of formation in Urumqi are analyzed.It turns out: the global solar radiation and direct solar radiation are decreasing before 1990,increasing after 1990.On the contrary,the scattering solar radiation is increasing before 1986,descending after 1986.The preliminary conclusions were drawn that the decrease of total cloud cover,the increase of low cloud cover and the slower downtrend of relative humidity were the main effects on the solar radiation changes.From these changes indicated indirectly the air pollution of Urumqi is reducing gradually in recent 30 years. |
