Mechanisms for the Influence from Ice Nucleus Aerosols on Clouds and their indirect effects: Cloud modelling

6 October 2023 13:00 | Thesis defence

The public defence for Deepak Waman in Geobiosphere Science with Specialization in Physical Geography and Ecosystem Science

The role of multiple groups of primary biological aerosol particles (PBAPs) as ice nucleating particles (INPs), and of ice formation processes such as time-dependent freezing of various INPs, and various secondary ice production
(SIP) mechanisms in overall ice concentration, has been evaluated in a range of cloud systems by simulating them numerically with the state-of-the-art ‘Aerosol-Cloud’ (AC) model in a 3D mesoscale domain.

Also, the mechanisms mof aerosol indirect effects (AIEs) arising from anthropogenic INPs, and the responses to these AIEs from time-dependent INP freezing and SIP processes are investigated in the simulated clouds.
