Earth atmosphere is uniquely regulated by water cycle. It spans wide spatiotemporal spectrum and many layers of governing physics. Through interactions with energy cycle and circulation, the moisture and cloud of highly fluctuating nature exhibit surprisingly coherent large-scale structure. The corresponding convective-radiative processes relevant in climate oscillations of different scales are essential part of 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 (tropical waves) and climate oscillations (the MJO and ENSO) as well as mechanisms maintaining convective-radiative 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.

地球大氣受水循環調節，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。其間對流輻射過程為影響氣候震盪與平衡的重要動力機制。
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。
