My current research focuses on two major areas:
To improve the weather forecasting system by enhancing the representation of land surface hydrology/boundary layer physical processes/urban morphology.
Application of CMAQ air quality modeling to study Taiwan’s air quality problem.
The following are lists of the specific tasks:
Boundary layer meteorology
Turbulent transport and diffusion processes
Land-air energy exchange processes
Urban Meteorology/Climatology
Large eddy simulation
Land-Sea Breeze/Mountain-Valley Wind over complex topography
Air Quality Modeling (Community Multiscale Air Quality Modeling):
Effect of the meteorological process on the transport and diffusion of air pollutants.
Ozone Chemistry/Aerosols
Source-receptor relationship and source apportionment
Mechanisms lead to the extreme air pollution episode
Development of the air pollution control strategy
Land surface hydrology:
Feedback of land-hydrologic processes on land surface energy exchange processes
Surface evapotranspiration processes
Surface and subsurface run-off processes
Long-term impact on regional climate
