Hydrological impacts on seasonal sea level change

In this paper, we present some extended results of hydrological impacts on seasonal sea level change using a few different hydrological models and an updated steric model, and compare with the results of Chen et al. [Geophys. Res. Lett., 25 (19) (1998) 3555] and Minster et al. [Global Planet. Change, 20 (1999) 157]. Even though different hydrological models show significant discrepancies in seasonal water storage change at local scales, most of the model-derived seasonal global mean sea level (GMSL) changes agree well with TOPEX/Poseidon (T/P) data. This further increases our confidence in using TOPEX/Poseidon satellite altimeter data, especially when combined with the TOPEX/Poseidon extended mission, Jason-1ʹs data to provide observational constraints on water mass budget of global atmospheric and hydrological models.
