Investigating apparent aerosol effects on precipitation in climate model simulations
Aerosols in the atmosphere serve as condensation nuclei for the cloud formation. This brings an important influence on the microphysical properties of cloud water that in turn affect the processes in the formation of precipitation. Aerosol-cloud-precipitation interaction which simultaneously change cloud albedo interest many studies to find out aerosol impact on precipitation formation. The studies were done by observation measurement and simulation. UK Met Office Unified Model (UM) is one model that includes aerosol direct and indirect effect in the NWP configuration which leads to study aero ...

Aerosols in the atmosphere serve as condensation nuclei for the cloud formation. This brings an important influence on the microphysical properties of cloud water that in turn affect the processes in the formation of precipitation. Aerosol-cloud-precipitation interaction which simultaneously change cloud albedo interest many studies to find out aerosol impact on precipitation formation. The studies were done by observation measurement and simulation. UK Met Office Unified Model (UM) is one model that includes aerosol direct and indirect effect in the NWP configuration which leads to study aerosol impact on precipitation. Recent study use UM to simulate precipitation susceptibility when using aerosol-cloud interaction and no aerosol-cloud interaction which both showing precipitation dependency on aerosol. This dissertation investigate what particular factor and process leads to the apparent precipitation susceptibility by using UM SCM (Single Column Model) to simulate marine boundary-layer clouds and investigate several factor that may cause the apparent precipitation susceptibility including wind and time steps. Simulation with applying different horizontal and vertical wind tendency and time steps was done. Precipitation susceptibility found to be sensitive with the time step choices and wind tendency.
