Share Your Ideas on Growing LASSO Part 5: Clear-Air Turbulence
Editor’s note: William Gustafson, principal investigator for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) workflow, sent in this update. Large-eddy simulation (LES) has a long history of being used to simulate clear-air turbulence (i.e., dry convection) in the planetary boundary layer. Would this be a beneficial mode of expansion for the Atmospheric…
