Adaptive method of lines for multi-component aerosol condensational growth and CCN activation [PDF]
Geoscientific Model Development, 2011 The process of formation of cloud droplets on an ensemble of aerosol particles is modelled by numerous investigators using the method of lines (MOL). The method involves discretisation of the aerosol size spectrum into bins whose positions evolve with ...

Impact of high- and low-vorticity turbulence on cloud–environment mixing and cloud microphysics processes [PDF]
Atmospheric Chemistry and Physics, 2021 Turbulent mixing of dry air affects the evolution of the cloud droplet size spectrum via various mechanisms. In a turbulent cloud, high- and low-vorticity regions coexist, and inertial clustering of cloud droplets can occur in low-vorticity regions.
