Abstract:Based on the ECMWF global atmospheric model and the daily data of the surface climatological data in China, the pressure data of the meteorological stations in Xinjiang and surrounding areas are concentrated. According to the theory of elastic crustal deformation, the method of removal and recovery is adopted, and Green’s function and the spherical harmonic function method are used to study and calculate its effect on atmospheric load on the vertical and horizontal deformation of the crust, during the period from 2011 to 2015 in Xinjiang and the surrounding area. At the same time, the atmospheric admittance method is used to calculate the influence of atmospheric variance on ground gravity. The results indicate: 1) the influence of atmospheric load on vertical deformation in Xinjiang reaches the centimeter level, and the influence on ground gravity can reach 10 μGal; 2) the influence of atmospheric load has significant seasonality.
