Workshop: Stratospheric predictability and impact on the troposphere
Oral presentation
This talk presents an overview of evidence, from the Met Office seasonal to decadal forecasting team, of the impact of the stratosphere on surface climate in observations and models. Stratospheric sudden warmings can be predicted deterministically almost two weeks in advance, impact the North Atlantic Oscillation, and enhance skill in seasonal forecasts. ENSO, and the Quasi-Biennial...
