摘要: 利用塔克拉玛干沙漠塔中大气环境观测试验站2007年1月至2011年12月总辐射、散射辐射和直接辐射观测资料,分析了塔克拉玛干沙漠腹地太阳总辐射、散射辐射和水平面直接辐射的主要特征。结果表明:塔克拉玛干沙漠腹地总辐射、散射辐射和水平面直接辐射平均年总量分别为6619.0、3507.8和2203.5 MJ?m-2。典型晴天总辐射日峰值分别为散射辐射的2.4倍和直接辐射的1.5倍。沙尘暴天散射辐射值增加到与总辐射基本一致,而直接辐射衰减最明显。当太阳高度角>20°时,散射辐射随总云量的增加而增大,且秋、冬两季增幅明显。

Abstract: In order to reveal the essential feature of radiation in extreme arid region of Northwest China, the characteristics of global radiation, direct radiation and diffuse radiation were analyzed by using solar irradiance observation data and meteorological data from January, 2007 to December, 2011. The results show that the annual total of global radiation, diffuse radiation and direct radiation were 6619.0, 3507.8, 2203.5 MJ·m-2, respectively. The daily peak of global radiation is 2.4 times of diffuse radiation and 1.5 times of direct radiation in the clear day. In the sand storm day, the value of diffuse radiation increases to be consistent with the global radiation, and direct radiation attenuation is obvious. Diffuse radiation increases with the total cloud amount rise when the solar zenith angle is higher than 20°, and it increases significantly in autumn and winter.

Key words: Taklimakan Desert, global radiation, diffuse radiation, direct radiation
