Fig. 7: Large-scale atmospheric patterns associated with each MHW group.
From: Characteristics and drivers of marine heatwaves in the western South Atlantic
Composite of geopotential height anomalies at 200 hPa for each MHW group. Geopotential height anomalies at 200 hPa are represented in colour shading (in m) and zonal wind at 850 hPa in grey solid contours (in m s−1). The contour intervals are 5 m s−1, starting at 20 m s−1. The black contours delimit regions where composites are statistically significant at the 95% confidence level. The right panels indicate the intensity of the MHWs for each group, as in Fig. 3a–g.
