RESEARCH INTERESTS
My research interests are the indirect effect of aerosols on low-level clouds and fog (LLCF) and warm-season precipitation regimes in mountainous regions and ground validation of space-based remote sensing systems. Specifically, a cloud parcel model is implemented and coupled with Duke's Rain Microphysics Column Model to investigate the influence of aerosol properties on cloud development and orographic precipitation processes. I use the Weather Research and Forecasting (WRF) model at high-resolution to investigate Aerosol-Cloud-Precipitation-Interactions and elucidate the linkage of aerosol effects to the spatial pattern and diurnal cycle of LLCF and precipitation on altitudinal gradients.
