My major research interests are to understand the mean state of climate, in particular the large-scale atmospheric circulation, and its variability on various timescales from intraseasonal to inderdecadal. In recent years, I have developed and utilized a hierarchy of models ranging from a simple theoretical one to the state-of-the-art global climate model to deal with the above issues.
