Fig. 2: Zonal-mean zonal wind response to future sea-ice loss and its association with present-day neck region winds.
From: Jet stream response to future Arctic sea ice loss not underestimated by climate models
(colors) December-February (DJF) response to sea ice loss: a the multi-model mean, b the multi-model spread, as quantified by the difference between the three models with the strongest and the three models with the weakest tropospheric wind response, c the across-model correlation with the present-day neck region winds (uneck,pd), d the mean of the three models with the strongest uneck,pd, e the mean of the three models with the weakest uneck,pd, and f its difference. Contours in a show the present-day multi-model mean zonal-wind (contour interval: 10 m s-1), and in c and f the multi-model mean response (identical to the shading in a, contour interval: 0.2 m s-1). Black dots in c denote statistically significant correlations at a more than 95% confidence level. The black box in a (between 40 and 60°N and between 100 and 50 hPa) marks the region of the neck region winds, and the black boxes in b (between 600 and 150 hPa, and between 30 and 39°N for the low latitude and between 54 and 63°N for the high latitude box) mark the regions over which the tropospheric zonal wind response is calculated.
