Susceptibility simulations (with varying aerosol concentrations) were conducted for different model setups to investigate if the model can capture the transition from the aerosol- to the updraft-limited susceptibility regime.\r\n\r\nThe data was used to investigate if an LES code with explicit aerosol-cloud interactions and a widely used two-moment bulk microphysical scheme can reproduce the susceptibility regimes \u2014 i.e. the updraft-limited regime (typically occurring at high aerosol number concentrations and low updraft speeds) and the aerosol-limited regime (typically occurring at low aerosol number concentrations and high updraft speeds) \u2014 identified by detailed parcel model simulations and observations.","citations":"Schwarz M, Savre J, Sudhakar D, Quaas J, Ekman AML (2024) The Transition from Aerosol- to Updraft-Limited Susceptibility Regime in Large-Eddy Simulations with Bulk Microphysics.
