My research interest focuses on atmospheric modeling. I am particularly interested in mesoscale processes, regional climate change and extreme events, climate projection and its impact study, land and atmosphere interaction, atmospheric chemistry and aerosol, and their interaction with climate, atmospheric transport and general circulation, earth system modeling.
GCM ARPEGE simulations were dynamically downscaled for the study of climate change and its impact on grapevine growth in Burgundy region in France by the mid 21st century. The surface temperature were simulated at 8 km x 8 km horizontal resolution for 1970-1979 and 2031-2040 under A2 emission scenario. The work also include derive of initial soil moisture and model evaluation. The resulting potential warming rates were used to simulate the grape (Pinot noir grape variety) flowering and véraison dates in the future.
High resolution climate downscaling by the NORESM-WRF was performed to provide climate information to the Bergen-Hardanger regional transport and construction plannings. Because this region has highly complex topography, the horizontal resolution is chosen at 1km x 1km. It was found that wind speed has better correlations when increasing horizontal resolution to 1 km, and landuse has large impact on surface parameters.
Texas regional storm events was simulated by WRF model over San Antonio River Basin in 2002, which is one of the biggest storms during past hundred years. The study focused on simulation of precipitation.
