青藏高原风电场开发对气候变化的影响研究

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。

A Research of climate change with wind farm development over Qinghai Tibet Plateau

The climate change in China is simulated by the global atmospheric circulation model BCC_AGCM2.0, through the momentum and thermal forcing of different regions and different roughness changes with the wind farm developmentin Qinghai Tibet Plateau. The results show that the climate effect is obvious in China. The precipitation in summer in North China and the temperature in winter is decreased with the thermodynamic forcing. Similarly, the precipitation in summer and the temperature in winter are increased in the southern China with dynamical forcing. With the increase of roughness, the winter water vapor transport in the south of Yangtze River and the summer vapor in the North China on 850hPa are obviously decreasing trend.
