| Outline of Final Research Achievements |
Dynamical linkage among internal and/or external variations in the stratosphere-troposphere coupled system was investigated comprehensively by the combination of data analyses and numerical model experiments. We showed not only that variations in the troposphere affect variations in the stratosphere, but also that the wave reflection in the stratosphere and variations of the circulation/ozone distribution can affect the occurrence of cold surge and variations of precipitation/temperature in the troposphere, respectively. These results can have an impact on understanding of climate variations and change in the troposphere.
