摘要
高原山地占青藏高原总面积一半以上,认识其地气间物质和能量交换过程对于整个青藏高原的水热平衡有重要作用。过去20年里,我们在以喜马拉雅山为代表的青藏高原大型山地地区开展了多次综合观测实验,获得了高时空分辨率的地气交换观测资料。基于上述数据,结合高原其他地区的观测资料及大尺度再分析资料,我们又系统研究了高原山地特有的局地环流系统及地气交换过程,定量分析了高原山地低层大气过程的非均匀性及对南亚夏季风的响应,并将研究结果应用于川藏铁路建设中,特别是川藏铁路深切峡谷极端风场对特大桥梁的影响。基于这些研究,本文总结了高原山地气象学的有关进展,并展望了其未来的发展趋势。
More than half of the Tibetan Plateau is covered by the great mountain systems,therefore,the land-atmosphere mass and heat exchange processes over the plateau mountains are essentially important for the total heat and moisture balance over the whole Tibetan Plateau.Over the past 20 years,many comprehensive experiments have been carried out over the Himalayas,and the high spatialtemporal resolution of land-atmosphere exchange processes were obtained.Based on the above observational data,as well as the reanalysis data,we have systematically analyzed the local circulations and the related land-atmosphere mass and heat transfers over the plateau mountain regions.The inhomogeneous lower atmospheric processes has been analyzed,as well as their responses to evolutions of the South Asian summer monsoon.All the above observational results have also been applied to the construction of Sichuan-Xizang Railway,especially impacts of the extreme wind over the deep-cut canyons on the great bridges.Based on these studies,this paper summarizes the relevant advances in the meteorology of plateau mountains and outlines prospects for its future development trends.
