Research Field

Climate modeling, Climate dynamics, Dynamics of the large-scale atmospheric circulation

Current Research

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. Specific research topics include:
* Dynamics of the annular mode* Midlatitude atmosphere-ocean interaction* Dynamical processes associated with the ENSO teleconnection * Development and application of the linear stochastic modeling (LBM) to the low-frequency variability in the large-scale atmosphere* Multi-scale interaction associated with clouds using the GCM and CRM* Predictability of the atmospheric circulation
