My PhD project aims of investigating the freezing mechanisms and aerosol-cloud interactions in mixed-phase clouds with the global climate model ECHAM HAM. The focus will be on the influence of aerosols on the formation of mixed-phase clouds (freezing processes) especially in the Arctic. Read more.
For that purpose a new parameterization of freezing processes in mixed-phase clouds is implemented into ECHAM HAM, which is based on the Classical Nucleation Theory. This new parameterization scheme makes it feasible to incorporate different lab measurements (read more).
To test and verify the parameterization scheme some case studies focusing on the Arctic will be investigated.
Later on the impact of aerosol-cloud interactions on current and future climate will be further analysed on a global scale.
