It has always been fascinating for me to study the life cycle of clouds. My research interests include convection and precipitation, as well as the interaction among land surface, atmospheric boundary layer, and clouds. I make observational analysis using both in-situ and remote sensing data from field campaigns or longterm observations at DOE ARM climate facilities. I perform numerical modeling and analysis using fine-scale modeling tools such as large eddy simulations, as well as global climate models with parameterized cloud and convection processes or super-parameterization such as Multi-scale Modeling Framework. I also develop forcing data sets to drive cloud resolving model or single-column model through constrained variational analysis to support DOE ASR cloud modeling activity for various field campaigns.
