"Surface Heterogeneity Induced Convection during HI-SCALE Field Campaign"

Presented by Jingyi Chen, Pacific Northwest National Lab

Thursday, February 4, 2021, 11:00 am — Videoconference / Virtual Event(videoconference link to be announced)

Shallow precipitating clouds are often a precursor to subsequent deep convection. This study investigates the land-atmosphere interactions and boundary layer processes that lead to the formation of such clouds observed over the Southern Great Plain during the Holistic Interactions of Shallow Clouds, Aerosols and Land-Ecosystems (HI-SCALE) field campaign in 2016. We conducted Large Eddy Simulations (LES) version of the Weather Research and Forecasting Model for a selected day with transition from clear-sky to shallow precipitating clouds and then to the deep convection transition. The results shed new lights on the understanding of the mechanisms of land-atmospheric interactions and convection initiations.
