4. Research Interests

The "Climate Dynamics and Air-Sea Interaction Laboratory" (abbreviated as "CDAS" Lab) at National Central University led by Dr. Jia-Yuh Yu is aiming at conducting fine research on several aspects of climate science to explore (1) how climate changes affect precipitation and circulation patterns on earth and the physical mechanisms attributing to such changes; (2) the impacts of global warming on ocean-atmospheric low-frequency oscillations, including intra-seasonal, inter-annual and inter-decadal timescales; (3) how natural and anthropogenic climate variability modulates tropical cyclone activity over the western North Pacific, based on physically-based statistical approaches and high-resolution climate model simulations.
