Numerical Simulations of Arctic Climate with Regional Atmospheric Models Based on Two Different Versions of WRF—Results of Annual Mean
Abstract: Numerical simulation test is made for Arctic climate with regional climate models based on WRF3.2.1 and PWRF3.3.1 versions, and simulation capabilities for Arctic climate of two versions are compared and analyzed. Ac- cording to results: within temperature field, simulation result of climate model based on WRF3.2.1 is relatively low; simulation result within potential height field is also relative low, and zones with larger difference are mainly around Victoria Island; within sea-level pressure field, for simulation based on WRF3.2.1 model, zone with low value is rela- tive large, and it is not as good as simulation based on PWRF3.3.1 model; Wind difference of both models exists up to high altitude, wind speed difference will increase with increasing of altitude, and max wind speed difference40m/s will be reached at 200 hPa; rainfall simulation results of both models are similar, simulation result for unsteady rainfall is relatively good, simulation result for steady rainfall shows position with northward difference and rainfall is relatively large, and rainfall simulation result in whole is not good. In numerical simulation test, performance of climate model based on PWRF3.3.1 is better than one based on WRF3.2.1 inwhole.
