2.4: To enhance collaboration between observational communities and OceanPredict (Contribution to OceanObs’19)

Theme 2 – Splinter 4
Abstracts of session 2.4 Chaired by Elisabeth Remy

This splinter session introduces some coordinated efforts on construction of effective observing systems and observing system evaluation in order to realize more reliable ocean predictions. Through this section, we try to contribute to OceanObs’19 by discussing the strategy to enhace the collaboration between obsrvational and OceanPredict communities.

3.4: Applications and advances in simulating sea ice

Theme 3 – Splinter 4
Abstracts of session 3.4 Chaired by Moninya Roughan

The overarching goal of the Theme 3 session is to bring forward the latest developments in ocean modeling and forecasting from a combined physical and biogeochemical perspective. The first two splinter sessions emphasize ocean, atmosphere, and ice forecasts and nowcasts. The third session focuses on biogeochemical and ecological applications. The fourth deals with the latest advances in sea ice modeling and prediction. Finally, the last session emphasizes the small scales.

4.2: Variational, ensemble and hybrid methods in ocean data assimilation II

Theme 4 – Splinter 2
Abstracts of session 4.2 Chaired by Matt Martin and Hans Ngodock

Data assimilation methods can be broadly split into two types: variational and ensemble. Recently aspects of the two approaches have been combined in hybrid ensemble/variational methods. These first two splinter sessions cover applications of these various approaches in ocean data assimilation systems.

5.4: Global and Regional Prediction Systems II

Theme 5 – Splinter 4
Abstracts of session 5.4 Chaired by Guimei Liu and Simona Masina

This is one of three consecutive sessions showcasing global and regional prediction systems being developed or run operationally.  This will include system descriptions, latest developments in the use of observations, and the practical considerations of running increasingly complicated operational systems so as to produce model outputs which are useful to users in a timely manner.  The second of these sessions has an emphasis on high resolution regional and coastal modelling systems including interactions with the systems in which they are nested.
