| Research Abstract |
It is well recognized that the Japanese geostationary meteorological satellites, GMS/MTSAT or Himawari series, drastically improved the prediction of typhoons. The satellite resides at 140E over the equator and provides us with a comprehensive view of cloud activity over the western pacific every hour. Although the seen of GMS well cover the western Pacific area, the South East China and India is at the western merge of the GMS view. Since the Asian countries are affected by Asian summer monsoon and are suffered by severe weather associated to monsoon, it is highly required to monitor monsoon activity. In order to do this, the data observed from the Chinese geostationary meteorological satellite, Feng-Yun 2 series which resides at 105 E over the Singapore, is very useful.
The first Chinese operational meteorological satellite, Feng-Yun 2C is officially in operation on early May in 2005 after an experimental satellite Feng-Yun 2B. The observed data are transmitted in the HiRID format. The Disaster Prevention Research Institute started to receive the data since the area of Fenf-Yun 2B. The precision of the data is compared with that of GMS/MTSAT observation, and it is confirmed that the data are really consistent with GMS/MTSAT observation.
The FY-2C provides information from Arabian Sea to Maritime Continents, so that if the images are combined with GMS/MTSAT data, typhoons which hit south east China are consistently tracked from Pacific area to the Vietnam, the cyclone which landed on Bangladesh is firstly identified by FY-2C and the extra-tropical transition and the succeeding influence to China and Japan are well monitored by GMS/MTSAT. In Equatorial regions, the MJO is continuously monitored from Indian Ocean through Pacific Ocean in the combined images. The DPRI is now showing some images in south Asia in the web-site.
