Research Abstract |
In this research, a cloud microphysics data assimilation technique using observation data by satellite microwave radiometer is improved by cloud top height estimated from Multi-functional Transport Satellite (MTSAT). Weather forecasting experiments using the data assimilation results show improvement of rainfall distribution over the ocean. At the same time, sensitivity assimilation experiments with varying cloud bottom height and an assimilation experiments with cloud bottom height observed by ceilometer show significant effects in assimilation results. These results indicate importance of cloud bottom height in the cloud microphysics data assimilation.
