Abstract First, we use wavelet to transform decomposition and reconstruction of ZTD time series of IGS stations in China, and then compare low-frequency trend and high-frequency cycle terms of ZTD with annual precipitation, analyzing their relationship with annual precipitation, and analyzing the causal relation with climate data. The results show that the low-frequency trend is the same as the trend of annual precipitation, there is a good correspondence between the high-frequency cycle terms and the annual precipitation variation, and the peak of high-frequency annual cycle terms corresponds to the peak of annual precipitation.
