Cloud physics is one of the key processes in modeling
studies of climate change, especially for global warming.
Improvement of cloud processes is necessary for accurate
simulations by global models. Cloud processes are also
core processes in simulations of high-impact weather
systems such as heavy rainfalls and typhoons. The cloud
modeling team will focus on addressing four objectives.
First, the cloud microphysics of the "Cloud Resolving Storm
Simulator (CReSS)" model will be improved. The dynamic
part of the CReSS model will also be improved for accurate
and high-speed calculation. Second, the cloud parameters
of global models will be examined using the CReSS model.
Satellite observations are used for verification of the
cloud modeling. Third, the CReSS model will be coupled
with global models interactively for accurate modeling of
convective regions. In particular, convective clouds in the
tropical region and typhoons will be studied using the models. Fourth, the CReSS model will be used for typhoon
research. This aims to contribute to verifications of typhoon simulations made by global models, and to accurate
and quantitative evaluations of typhoon impacts on human society under the present and warming climates.
