The Earth climate is uniquely regulated by water vapor and clouds in the water cycle that are governed by convective processes of highly fluctuating nature. Yet, climate oscillations of different spatiotemporal scales exhibit surprisingly coherent large-scale structure. This indicates interactions of water cycles among water vapor, clouds, and circulation with energy cycle involving radiation in the climate system. Such convection-radiation-circulation coupled processes of different scales are essential climate dynamic.
This course is designed to be a graduate level (both MS and Ph.D.) course, with emphasis on interactions between convection and tropical weather (CCEWs) and climate oscillations (MJO, ENSO, decadal oscillations) as well as mechanisms maintaining convective-radiative quasi-equilibrium. One half to two third of the course is taught by lectures covering the fundamentals, bibliographic survey, literature reading [basic and general references]. The rest of the course time will be devoted to observational and modeling analysis.

地球氣候受大氣水循環調節，過程橫跨多重尺度，分別由不同層面的物理系統控制。但尺度多變的雲雨水氣與環流的交互作用，卻呈現出協調的大尺度結構。其間對流、輻射、動力連動過程為影響氣候震盪(平衡態)的重要機制。
本課程主要對象為碩博士班研究生，側重熱帶氣候與對流的聯結，水氣在低頻震盪如MJO與年際變化所扮演的角色。約二分之一的課程內容為講述基本動力概念，另二分之一為閱讀文獻，探討對流輻射與氣候互動的機制。
