| Abstract: | To assess the effects of spatial resolutions of regional climate models that are used for the simulation of summer surface air temperatures(SATs) over China,the regional climate model RegCM3 is employed for a 5-year(2000-2004) long simulation of summer SATs over a fixed domain within China by choosing 3 horizontal resolutions(30,60 and 90 km) and 3 vertical resolutions(14,18,and 23 layers).The assessment is carried out in terms of several parameters,e.g.,simulated bias,root mean square error,and spatial cor... |
