摘要
利用全球大气环流模式BCC_AGCM2.0,通过青藏高原不同区域不同粗糙度的改变,模拟了青藏高原风电场开发造成的动力和热力强迫扰动对我国气候变化的影响。模拟结果表明,青藏高原热力场和动力场扰动对我国不同区域气候变化有着显著的影响,热力场的扰动会使华北地区的夏季降水明显减少,长江以南地区冬季气温降低,而动力场的扰动则会引起南方地区夏季降水增加,冬季气温明显上升。而且随着粗糙度的增大,长江以南地区冬季850 hPa水汽输送明显减小,而华北地区夏季的水汽输送也呈现出显著减少趋势。
The global atmospheric circulation model （BCC_AGCM2.0） is used to simulate the influence of the dynamic and thermodynamic forcing on the climate change in China by the development of wind farm with the change of different roughness in different regions of the Tibet Plateau. The results showed that there was obvious influence on the climate change in the different regions of China with thermal and dynamic forcing over the Tibet Plateau. The thermal forcing obviously reduced the summer precipitation in North China, simultaneously, the winter temperature in the south of the Yangtze River would be reduced. The dynamic disturbance caused the summer precipitation in the southern region and the winter temperature increasing evidently. In addition, with the increase of roughness, the winter water vapor transporting on 850 hPa in the south of the Yangtze River decreased obviously, however, it showed a significant decreasing trend in summer over North China.
