3. Global Ocean fronts and eddies Animation Produced by Tim Schietlin, NCAR Top panel shows SST from a global climate model with 1/10 th deg. ocean. Bottom panel shows Reynolds et al. (2007) 1/4deg. OI SST for year 2004. Years are not intended to match.

4. Aims, Goals Overall Goal: Quantify effect of ocean fronts/eddies on climate – Local (time-mean, +variability) – Remote (time-mean, +variability) – Feedback on ocean and coupled response – Predictability? Possible specific aims – Describe the boundary layer response: dynamic/thermodynamic. Mechanisms & strength of response – Select the best atmospheric model schemes, resolutions (vertical/horizontal) – Select the appropriate surface condition (SST anomaly, flux anomaly) for use by atmospheric models – Coordinate model experiments – Critique analysis methods for describing ocean-atmosphere variability – Choose appropriate reanalysis/observations and time period for analysis – Quantify response of atmospheric synoptic systems to ocean fronts and mechanism of response – Summarize workshop for white paper – Etc.

5. Questions What kind of Models ? Atmosphere-only - GCM vs QGvs idealized models Atmosphere-mixed layer Fully coupled Resolution: Horizontal and vertical. Missing physics e.g. slantwise convection above fronts non-hydrostatic models? What observations ? Are new reanalyses better than old? Coupled better than atmos- only? Field experiments - do we have enough data from e.g. CLIMODE, KESS, HOT-SPOTS, Brazil- Malvinas ? How to best utilize recent in situ observations Satellite data - do we have sufficient data? Surface heat fluxes, pressure ? Post -QuikSCAT? Regular in-situ data - radiosondes, ARGO floats etc. What analysis ? How to separate forcing/feedbacks and Tropical/midlatitude processes. How to identify suitable record length from observations and model runs. Focus on mean climate or variability including extremes? What metrics? Algorithms - EOF, SVD, point correlation, lag correlation, LIM, etc etc. What timescales? Understanding the mechanisms ? Boundary layer dynamics, thermodynamics. What drives the deeper response in the atmosphere and beyond Remote teleconnections? Is there a feedback to ocean mesoscale features and larger circulations? Interaction of different spatial scales: ocean- atmosphere
