Workshop: Stratospheric predictability and impact on the troposphere

ECMWF | Reading | 18-21 November 2019


This workshop will bring together experts to discuss and propose ways forward in representing the stratosphere in current and future numerical weather prediction models (1-50 km resolution, forecast lead times from medium-range to seasonal), and pathways by which better treatment of the stratosphere can improve predictive skill in the troposphere. The topics will include understanding and diagnosing stratosphere-troposphere interactions, improved parametrizations and numerical schemes, the role of water vapour and ozone, observational evaluation and data assimilation. The aim of the workshop is to provide guidance to ECMWF on the priorities for representing the stratosphere in the coming decade.
