Analysis of the Impact of Atmospheric Load Effect on Zhejiang Province
Abstract In this paper, based on the global atmospheric model and the data of Zhejiang regional meteorological station, the load deformation field and the change of gravity field caused by atmospheric pressure are calculated by the method of removing and restoring according to the load theory. The results show that the vertical deformation caused by atmospheric load in Zhejiang province reaches 12.1 mm, and the ground gravity change caused by atmospheric load exceeds 12 μGal. The influence of vertical deviation is small, and the atmospheric load has obvious annual periodicity and seasonality.
Key words :
atmospheric load
Green’s function
spherical harmonic function
