How does regional convection-permitting modeling improve the simulation of the atmospheric water cycle in spring over the Tibetan Plateau?

The Tibetan Plateau (TP) provides vital water resources for downstream regions, with spring precipitation contributing considerably to the annual totals over the southeastern TP. The added value of convection-permitting modeling in simulating the spring climate over the TP is uncertain. Here, we conducted and compared decade-long regional convection-permitting (3.3km) and convection-parameterized (13.2km) Icosahedral Nonhydrostatic Weather and Climate Model (ICON) simulations to reproduce the atmospheric water cycle in spring over the TP. Here is the associated datasets, including 3.3km convection permitting simulation, 13.2km convection parameterized simulations, 13.2km convection permitting simulation. Three Spring (MAM) mean variables averaged for the period 2010-2020 are included: precipitation, evaporation, water vapor transport. soil mositure at the first level is also attached.
