- Our Research
My research interests focused on understanding the Climate Change dynamical processes, such as the long time scale variation of tropical cyclone tracks & intensification, the large scale change of atmosphere circulation patterns (e.g. Indian & Asian monsoon), SST, Chl-a, & Ocean current anomaly from interannual to multidecadal events (e.g. ENSO, PDO and IOD). I used atmosphere, ocean & biochemical numerical models for simulation and I analyzed different kinds of observational data (e.g. station, mooring, satellite image and reanalysis data), covering the Indo-Pacific Ocean and Asian regions. All these study issues are very important for global environments especially extreme weather & water resources, because they affect the distribution and intensity change of precipitation over Asia region and the human activity and well-being.

Tropical Cyclones & Ocean Warm Eddy Interaction: Identifying the conditions under which a tropical cyclone (TC) undergoes rapid intensification (RI) remains to date a tremendous challenge in atmospheric science. Previous studies have shown that a TC passing over a warm ocean feature (WOF; e.g., warm eddy) can intensify (and conversely the storm may weaken when it passes over a cold eddy). In this study, we propose to systematically examine and quantify the effects of each of the above-mentioned processes on TC-intensification, under different TC translation speeds and with different sizes of the ocean eddy. The results show that the WOF increases surface enthalpy flux and moisture convergence in the storm’s core, resulting in stronger updrafts and intensity. However, the intensification rate is, in general, insufficiently rapid. Consequently, the number of RIs is not statistically significantly different between simulations with and without the WOF.

Tropical Deforestation & Climate Change: In the equatorial Malay Archipelago (Indonesia and Malaysia), tropical rainforest is lost on large scales to cash-crop plantation (oil palm, rubber and acacia, including fallow lands) and urban expansion. We found that deforestation into cash crops & urbanization change land surface properties and fluxes, and produce strong island warming compared to ocean SST. Despite the expansive land-cover change over a climatically sensitive region of the tropics, the resulting impact on the Asian summer monsoon has not been studied. We use a large ensemble of Atmospheric model experiments with observed and idealized land-cover-change specifications, and show that the deforestation warms the Malay Archipelago, caused by an increase in soil warming due to decreased evapotranspirative cooling.
