| Outline of Final Research Achievements |
We analyzed large-scale tropical waves in the upper troposphere and around the tropopause and clarified the properties of cloud activity that can be sources of the tropical waves. With using the data obtained in the international special observation in September-December 2011, we detected the dominant variability of cirrus activity with the scale of several days and found that it is accompanied with the equatorial trapped inertial gravity waves. We also investigated the properties of large-scale simultaneous meridional separation of the cloud bands in the intertropical convergence zone with the combination of several datasets. Furthermore, we completed the database of cloud top height with using the geostationary satellite infrared data and opened on the internet.
