全球气候变暖毋庸置疑,其结果必然对陆面水分循环产生影响.然而,由于受到全球地表水文观测资料的限制,目前关于气候变化对陆面水循环的影响及其机理的认识还十分有限.在全球变暖的大背景下,陆面水循环对气候变化的响应如何?其对气候变化最为敏感的热点区域位于何处?为了回答上述科学问题,研究选用美国国家大气研究中心(NCAR)的公用陆面 There is no doubt that global warming will inevitably have an impact on the water cycle of the land surface, however, due to the limitation of global surface hydrological observations, the current understanding of the impact of climate change on the water cycle of the continental surface and its mechanism is still very limited. In the context of global warming, what is the response of the land-surface water cycle to climate change and where are its hot spots most sensitive to climate change? In order to answer the above scientific questions, the NCAR public land surface
