Introduction of Research

My research field is meteorology, especially cloud, aerosol, lightning, and their effect on the human life. I'm researching them using the numerical simulation. During my research activity, I have experience using super computer like K computer, Earth Simulator, and so on. As well as the aerosol, cloud and lightning, I have been contributing the research project targeting on the radionuclide emitted from nuclear power plant to atmosphere using the numerical simulation.
Development of the numerical weather/climate model is also my research topic.
