| Outline of Final Research Achievements |
The Quasi-biennial oscillation (QBO) and semi-annual oscillation (SAO) was successfully simulated by the climate model without non-stationary gravity wave parameterization. The mechanism of interannual variability of stratospheric water vapor was clarified by analyzing the climate model and satellite data. The experiments of the QBO modulation in a future climate were done following the international project, and modulations of the QBO were investigated.
We participated in the stratosphere reanalyses intercomparison project (S-RIP). Several studies are published, such as representations of equatorial stratospheric zonal winds, comparison of mean meridional circulation and mixture processes, comparison of seasonal and interannual variations in dynamical fields etc.
