Abstract EN
The regional climate model, RegCM3, is used to simulate the 2004 summer surface air temperature (SAT) and precipitation at different horizontal (i.e., 30, 60, and 90 km) and vertical resolutions (i.e., 14, 18, and 23 layers).
Results showed that increasing resolution evidently changes simulated SATs with regional characteristics.
For example, simulated SATs are apparently better produced when horizontal resolution increases from 60 to 30 km under the 23 layers.
Meanwhile, the SATs over the entire area are more sensitive to vertical resolution than horizontal resolution.
The subareas present higher sensitivities than the total area, with larger horizontal resolution effects than those of vertical resolution.
For precipitation, increasing resolution shows higher impact compared to SAT, with higher sensitivity induced by vertical resolution than by horizontal resolution, especially in rainy South China.
The best SAT/precipitation can be produced only when the horizontal and vertical resolutions are reasonably configured.
This indicates that different resolutions lead to different atmospheric thermodynamic states.
Because of the dry climate and low soil heat capacity in Northern China, resolution changes easily modify surface energy fluxes, hence the SAT; due to the rainy and humid climate in South China, resolution changes likely strongly influence grid-scale structure of clouds and therefore precipitation.
