| Research Abstract |
We develop a cloud-resolving model including aerosol processes. The aerosol processes of advection, diffusion, gravitational settling, dry deposition, and wet deposition have already been installed. Using the model, we reproduced well the tracing of an aerosol category released from the Fukushima Nuclear Power Plant on March 15, 2011 and the deposition of it on the northern Kanto and Nakadori (Fukushima) regions.
However, we cannot complete the nucleation processes that the aerosol particles act as CCN and/or IN. Although a cloud-resolving model has the two-moment bulk microphysical processes for liquid phase, however, cloud particles cannot develop to raindrops in simple simulations using the model. We are willing to solve the problem after the project finished.
