          Climate predictions on weekly, monthly, seasonal and annual timescales involves many processes that operate among the atmosphere, ocean and land surface. Monitoring and analyzing the weekly to interannual climate variability is an efficient way to enhance our understanding of global and regional climate variability and the relationship with high-impact weather events.
          This course is designed to be a graduate level (both MS and Ph.D) course, with emphasis on learning about how to talk about natural variability from weekly to interannual time scales, and the fundamental statistical/quantitative methods used to diagnose the natural variability. The diagnostics aims to assess the nature of climate variations on differing time scales.
          The class will be a mixture of lectures, discussions, and student presentations. Half of the course is taught by interactive-oriented lectures covering the major topics that is relevant to the real-time climate monitoring and discussion. The rest of the course time will be devoted to observational and forecast data analysis and student presentations. There will be homework and midterm progress report to cover the lectures and a final oral presentation and written report on topic chosen by students.

          2

          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.
