      夏季风过渡区是受夏季风影响最敏感的区域之一，其陆-气相互作用对夏季风气候动力学过程响应明显，该区域的陆-气相互作用及其对夏季风活动的响应是一个值得关注的重要科学问题。分析了中国夏季风过渡区的形成及其基本特征，讨论了夏季风过渡区陆-气相互作用过程研究的主要关注点，初步推测了该地区陆-气相互作用对夏季风变化的响应机制。指出该地区陆-气相互作用研究包含了多重互馈机制、陆面水-热-生过程耦合、近地层到自由大气的多界面交换、季风多尺度作用和特殊的陆面水分循环等一系列重要科学问题。同时，总结归纳了该领域的主要研究进展和关键科学问题，提出了未来应该重点研究的7个方面，并初步给出了研究试验的基本思路。为未来系统深入研究夏季风过渡区陆-气相互作用及其对夏季风活动响应问题提供了科学指导。

英文摘要:

      The summer monsoon transition zone (SMTZ) is one of the most sensitive areas affected by summer monsoon. Land-atmosphere interaction in the transition zone and its response to summer monsoon is an important scientific issue. In this study, we analyze the formation and basic characteristics of the SMTZ, discuss a few main issues of land-atmosphere interaction process in the SMTZ, and preliminarily propose the responding mechanism of land-atmosphere interaction to variations of summer monsoon. It is stated that the land-atmosphere interaction in the SMTZ contains multi-feedback mechanisms, including the water-heat-ecology coupling process on the surface, multi-interface exchanges from near surface to free atmosphere, and multi-scale interaction of summer monsoon and special hydrological cycle of the land surface. Meanwhile, main progresses, key scientific issues, seven research fields that should be focused on, and basic methods of experiments have been preliminarily proposed. The present study provides a guideline for the study of land-atmosphere interaction and its response to summer monsoon in the future.
