The Workshop on Atmosphere-Ocean Interaction was held from 10 to 12 November 2008.
Description
The workshop addressed the requirements for ocean-atmosphere coupling from the very short time scales to the monthly time range with focus on ocean near-surface processes.
Questions discussed included:
- Which processes need to be taken into account e.g. ocean waves, currents, diurnal cycle of SST, ocean mixed layer dynamics, horizontal resolution of SST?
- What is the impact of air-sea processes on atmospheric phenomena (including extreme events) e.g. tropical cyclones, extra-tropical explosive genesis, monsoons, MJO?
- Which models are the most appropriate at different time scales, and what are the implications for seamless forecasting?
