| Research Abstract |
The impact of direct airborn observations for typhoons in 2008 on the track forecast has been investigated. The result shows that the impact was positive in all models. However, the impact was small in the JMA or ECMWF models, which perform forecast performances better and it was large in the NCEP model, which has more error in track forecast. The result also suggests that the data assimilation near the center of the storm is critical for the track forecast. One of the research objectives in this project was to confirm the feasibility of the targeted observation. On this regard it is not fully confirmed, mainly because the observations are limited in two typhoon cases, Sinlaku and Jangmi. It has been revealed that the data assimilation over the high sensitive region did not give better forecast.
