Research Interests

Hongchen is broadly interested in numerical simulations of the Earth System in the past, present and future. Before joining LLNL, Hongchen was under the tutelage of Prof. Michael Pritchard at UC Irvine where he studied climate model representations of land-atmosphere coupling using conventional parameterized convection and prototype next-generation simulations with explicit convection. His numerical experiments revealed the effects of explicit convection on both the hydrological and thermal pathways of land-atmosphere coupling, with implications on global land surface Bowen ratio and its climate sensitivity. Here at the Lab, Hongchen aims to better understand the interactions between atmospheric convection and land surface climate over the Central U.S. by utilizing Convection-Permitting Model (CPM) simulations, DOE ARM site observations, and field campaigns.
