•Promote researches to clarify phenomena in the atmosphere-ocean-land system and evaluate hazards.
•Advanced utilization of numerical weather forecast model
 We study development of tropical cyclones, precipitation over steep terrain like Himalaya, etc. by use of numerical models. We also tackle problems of downscaling, which is necessary for advanced utilization of numerical model.
•Study on the mechanisms of torrential rainfall occurred in Tohoku region in summer
 We conduct numerical simulations using cloud-resolving models and compare the results with ground-based radar and rain gauge measurements of rainfall and satellite observations of 3-dimensional distribution of water vapor, cloud, and rain.
•Application of land-surface model to disaster science
 We study plant blight, frost damage, snowmelt flood, etc. because land-surface model can simulate plant and snow situation by meteorological data.
