Characteristics of Surface Radiation Budget in Changji Oasis,Xinjiang
The surface radiation observation data and weather phenomenon observation record data from March to November 2020 of the Dianba oasis area of Changji in Xinjiang,were used to quantitatively analyze the characteristics of surface radiation changes in Changji oasis area at different time scales and under different weather conditions.The results showed that:(1)There are seasonal differences between the daily mean value and the daily peak time of radiation components,and special weather phenomena has an impact on the radiation flux.(2)The monthly exposure to surface radiation varies significantly with seasons.(3)The monthly average daily variation of the surface albedo is obvious,and the surface albedo shows a smooth"U-shaped"curve on sunny days,and the curve changes irregularly and smoothly on non-sunny days.(4)The radiation component has unique daily variation characteristics under different weathers,and typical weather such as light fog,rainy days,strong winds,blowing sand,and cloudy days will bring different degrees of attenuation to the radiation component,and the attenuation of rainy days,strong winds and cloudy weather is the most obvious.
