Global Ocean fronts and eddies

• Animation Produced by Tim Schietlin, NCAR• Top panel shows SST from a global climate

model with 1/10th deg. ocean.• Bottom panel shows Reynolds et al. (2007)

1/4deg. OI SST for year 2004.• Years are not intended to match.

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.

QuestionsWhat 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 beyondRemote teleconnections?Is there a feedback to ocean mesoscale features and larger circulations?Interaction of different spatial scales: ocean-atmosphere
