Simulation of Extreme Precipitation in Four Climate Regions in China by General Circulation Models (GCMs): Performance and Projections
نویسندگان
چکیده
In the context of global climate change, it is important to monitor abnormal changes in extreme precipitation events that lead frequent floods. This research used indices describe variations and analyzed characteristics four climatic (arid, semi-arid, semi-humid humid) regions across China. The equidistant cumulative distribution function (EDCDF) method was downscale bias-correct daily eight Coupled Model Intercomparison Project Phase 5 (CMIP5) general circulation models (GCMs). From 1961 2005, humid region had stronger longer compared with other regions. future, projected mainly concentrated summer, there will be large areas substantial maximum consecutive 5-day (Rx5) intensity (SDII). greatest differences between two scenarios (RCP4.5 RCP8.5) are semi-arid for summer anomalies. However, area an increasing trend larger under RCP8.5 scenario than RCP4.5 scenario. future relatively pronounced, especially areas, implying a potential heightened flood risk these areas.

Simulation of Climate by a Global General Circulation Model
The primitive equations of motion in spherical coordinates are integrated with respect to time on global grids with mean horizontal resolutions of ,500 and 250 km. There are nine levels in the models from 80 m to 28 km above the ground. The models have realistic continents with smoothed topography and an ocean surface with February water temperatures prescribed. The insolation is for a Northern...

The aim of this paper is to project extreme precipitation events in an arid and a semiarid station. In order to project climate change based on general circulation models (GCMs), we have applied LARS-WG[1] downscaling tool. This stochastic weather generator down-scaled the climate of two synoptic stations using HADCM3 model and A2 emission scenario for 2040. We extracted extreme precipitation e...
