Troposphere-Stratosphere Coupling in the Tropics: The Role of El Nino and the QBO
- 78 Downloads
The chemical composition and dynamics of the tropical stratosphere are largely determined by forcing from the underlying troposphere,transmitted through the tropical tropopause. The properties of the tropopause region of the atmosphere are reviewed, with emphasis on the roles of Pacific sea-surface temperature variability in the El Niño mode and the stratospheric QBO as the principal factors that determine interannual variations.
