Fig. 8: Teleconnections associated with marine heat waves in the coral sea and great barrier reef.
From: A large-scale view of marine heatwaves revealed by archetype analysis
a Sea-surface temperature (SST) anomaly; b surface air temperature (colours) with anomalous mid-tropospheric (500hPa) geopotential height (contour lines, contour interval 5m) and winds (vectors); and c subsurface ocean temperatures (averaged latitudinaly between 5°S and 5°N within the region indicated by dashed lines in panels a and b), associated with archetype #4; d The affiliation time-series (solid black) together with the multivariate El-Niño index (MEI, grey), and the Pacific South America (PSA) pattern index (blue). Periods of marine heatwaves are indicated by red shading. e The lagged cross-correlation between the affiliation time series and the MEI (grey) and the El-Niño Modoki Index (EMI) index (blue). Negative lags correspond to the MEI/EMI index leading the affiliation. Maps created with Cartopy71.
