Research Activities

Two-day Seminar at Meteorological Research Institute (October 25-26)
We invited eight trainees to give a lecture on the tropical cyclone-ocean interactions for two days (total of 10 hours). We also presented recent topics on Typhoons LAN and SAOLA.

Private lecture of JICA in 2007

Research on the improvement of typhoon track forecasting and objective intensity analysis
TC intensity change and rapid intensification processes are studied by using an atmosphere-wave-ocean coupled model on MRI super-computer system.

Clarification of cessation mechanisms of tropical cyclone intensification for developing tropical cyclone intensity forecasts
This project aims at understanding the processes how to stop intensification of tropical cyclones. The cessation mechanisms are investigated by using numerical simulations, various observations and data assimilation techniques.

Relationship between structure and intensity of typhoons clarified by using Doppler radar at Nansei Shoto and the Philippines and numerical simulations by a coupled atmosphere-wave-ocean model
The role in this research is to verify results of intensity estimation derived from Doppler radar observations at Nansei Shoto and the Philippines (e.g. Typhoon Haiyan in 2013) using a coupled atmosphere-wave-ocean coupled model.

Predictability of typhoons and atmospheric disturbances in the mid-latitude and their interactions with the Ocean
This study addresses uncertainties of atmospheric and oceanic initial conditions. This study first performs objective analysis during projected observations at areas of Kuroshio Extention and during typhoon events using LETKF methodology. In order to evaluate the uncertainties of atmospheric initial conditions, this study analyses error-covariances obtained by data assimilation. Third, numerical simulations and ensemble simulations are performed using a nonhydrostatic atmosphere-wave-ocean coupled model based on objective anasyses obtained by LETKF methodology and by the oceanic assimilation system. The purpose of this study is to clarify dynamical and physical processes associated with torrential rains and strong winds accompanied by typhoons and atmospheric disturbances.
