Investigating the Thompson Aerosol-Aware

This is to further investigate the Thompson Aerosol-Aware microphysics scheme.

• Found a scientific paper that used the Thompson Aerosol-Aware microphysics scheme to investigate fog in Namibia, Africa. https://doi.org/10.5194/acp-22-10221-2022

CCN and cloud droplet concentrations at a remote ocean site

Main Takeaways from the Paper.

"Sensitivity analysis of an aerosol-aware microphysics scheme in Weather Research and Forecasting (WRF) during case studies of fog in Namibia" paper.

• Using observations, we can parametrize the Thompson Aerosol-Aware to give more accurate predictions.

• They changed the cloud droplet concentration, the mean radius of the cloud condensation nuclei (CCN) ,and the updraft velocity.

Key Questions:

1. Why does the Thompson Aerosol-Aware scheme reduces Qc?

2. How does the vertical profile of the cloud droplet concentration look?

3. Will they disappear after a long time?
