The group of Ocean-Atmosphere Interaction developed the comprehensive researches through observation, theory, simulation and prediction and is characterized by the tropical air-sea interaction in the process of climate evolution. The main achievements are as follows: 

Propose the vorticity twisting mechanism and ocean gradient feedback mechanism for intra-seasonal scale air-sea interactions. These are used to analyze and understand the mechanisms of intraseasonal variations with a period of 20-90 days and monsoons. The research results reveal the influence mechanism of the internal processes of the ocean on the formation of typhoons, and explain the reason why the number of typhoons does not change significantly in the cases of El Niño and La Niña.

Innovatively construct a dynamic framework for tropical water cycle in climate change, including the "stratification change climate advection" dynamic mechanism for weakened atmospheric circulation, and the "warmer gets wetter" and "warmer gets higher" patterns of precipitation and clouds driven by sea surface warming. 

Quantify the main effects of the percentage changes in the multi-scale tropical water cycle processes on the global radiative feedback. Develop new cloud observation methods to provide an effective solution for the uncertainties in climate prediction.
