Workshop

Frontal Scale Air-Sea Interaction Workshop

Background

Many studies have identified a strong thermal and dynamical response of the atmospheric boundary layer to SST anomalies and gradients induced by ocean fronts and eddies. Additionally, in some regions such as the Gulf Stream and Kuroshio Extension, the response is shown to penetrate to the upper troposphere. Midlatitude storm tracks in particular appear to be affected.

This local response is now reasonably well studied and there are a few viable theories on this topic. Numerical weather and climate models typically reproduce boundary layer response qualitatively, but there are quantitative differences with observations (typically the model response is too weak, e.g. in wind stress response to SST gradients.)

An outstanding question is whether and how this local response can influence the far field and climate timescales. In models, estimation of this far-field, large-scale response will be constrained by the ability to well-simulate the local response. In observations and reanalysis, detection of the response in mid-latitudes is complicated by natural weather and climate variability.
