Outline of Final Research Achievements

Insufficient understanding of the processes relevant to aerosols, clouds, and precipitations leads to large uncertainties in the prediction of future climate change. We studied key processes that influence the climate by improving the understanding of aerosol microphysical properties (e.g. number and size distribution). Microphysical properties of clouds (number and size distribution), their relationship to the formation of raindrops, and wet removal of aerosols have been investigated through understanding of the basic processes. For this purpose we developed advanced techniques to measure aerosols, clouds, and aerosols in raindrops and made aircraft and ground-based observations. We also developed an advanced regional scale model, which precisely represents these processes. We validated the each element of the model by comparison with the observations. We estimated the effects of aerosols on clouds and precipitation by combining the model calculations and observations.
