Major research concerns involve an understanding of the earth climate changing mechanism from the paleo-climate to the future climate, and of the intraseasonal-to-multi-decadal variability.

 The proposing of hypothesis through a theoretical approach based on the dynamical system theory; the finding of the new phenomena by the analysis using the observation and model simulations; and the verifying of the hypothesis by numerical simulations using Earth Climate System Model are propelled by our Lab.
