热带降水是全球能量水份循环的重要环节。热带降水在全球变暖下的变化是目前国际上广泛关注的气候变化问题之一。回顾了近30年来关于热带降水在观测中的变化以及基于气候模式预估未来变化方面的研究进展；总结了目前在热带区域降水变化机制方面的国际前沿研究进展及研究方法；最后讨论了目前气候模式预估未来区域降水变化所遇到的模式间差异大等影响预估可信度的问题，展望未来研究中面临的主要挑战。

Since tropical rainfall is important in the global energy and hydrologic cycle, the tropical rainfall changes under global warming arise extensive attention around the world in recent decades. The advances in the observational studies and model projection for the tropical rainfall changes under global warming are reviewed here. The frontiers in the mechanism of regional tropical rainfall changes and the approaches of rainfall change research are summarized. The large intermodel spread in the multi-model projections, the sources of uncertainty and the methods to reduce the uncertainty are also introduced. In the last, the challenges about the tropical rainfall changes are discussed.
