研究方向:青藏高原气候动力学、亚洲季风,海-陆-气相互作用。

我的主要研究兴趣是从地球气候系统海-陆-气相互作用的视角出发,认识青藏高原对亚洲季风形成和变异的影响。冬季青藏高原大地形对西风气流的阻挡和抬升作用以及夏季其强大的热力作用是北半球大气环流系统的重要影响因子,亦是全球最强的副热带冬季风和夏季风之所以出现在东亚地区的根本原因。我的研究工作致力于回答如下科学问题:(1)为什么青藏高原对亚洲季风的形成和不同时间尺度变率产生如此重要的影响?(2)什么原因造成了青藏高原地表和大气热源(汇)的时空演变?(3)哪些类型的亚洲季风空间格局和时间变率直接受制于青藏高原的影响?(4)如何考虑青藏高原与大尺度海-气自然变率的协同效应,从而为亚洲季风预测提供有用的信息。我的研究方法主要是多源资料分析和数值模拟结合,模式工具包括全球和区域尺度的大气、海洋和海-气耦合模式。研究成果详见发表论文和承担项目。


Research Interest: Tibetan Plateau climate dynamics, Asian monsoon, land-air-sea interaction

My research focuses mainly on the impact of the Tibetan Plateau (TP) on the Asian monsoon formation, variability, and change in the framework of the global land-air-sea coupled system. The TP importance for climate is evident from the facts that both its mechanical forcing in winter and thermal forcing in summer exert significant influence on the atmospheric general circulation. This is the reason why the strongest subtropical winter and summer monsoon on earth appear in East Asia.My research contributes to answering such fundamental questions as why TP is so important for the formation and multi-scale variation of Asian monsoon, what determines the spatial and temporalevolution of the land and atmospheric heat source/sink over TP, how preferred patterns and variability of Asia monsoon are connected with the TP forcing, and how predictable climate in the Asian monsoon region can be determined by the signal originated from TP, together with the remote large-scale atmospheric and oceanic natural variability.I carry out both diagnostic and modeling studies, using observations and numerical models of the global and regional atmosphere, ocean,and their coupled system.
