Fig. 5

Composite differences between samples with and without SALLJ northern branch events (i.e., low-level jet sample minus low-level jet free sample). Top: Colors indicate OLR anomalies and contours show SST anomalies; vectors indicate anomalies in winds at 200 hPa. Bottom: as on top panel, but for wind anomalies at 850 hPa. Colored regions and vectors indicate anomalies in OLR and winds (in blue) that are statistically significant at 5% level. SST anomalies are not statistically significant, but are plotted for comparison with OLR anomalies. Gray shading indicates elevations >1500 m. Differences are computed for the entire 1 January 1979–31 December 2017 period for wind and SST anomalies and 1 January 1979–31 December 2016 for OLR
