Figure 1

(a) SST anomaly in the South Eastern Pacific on 26 May 1991. The coastal domain considered in the study is circled in black. The black box represents the equatorial region used to detect remote occurrences of MHWs. White dots indicate data point where the criterium for MHW detection is met. Agglomerations of white dots at \(\sim 11^{\circ}\,\hbox{S}\) and \(\sim 23^{\circ}\,\hbox{S}\) correspond to two spatially coherent MHW events. Histograms on the right side show the distribution of MHWs in the coastal region. (b) Number of MHWs sorted by duration and category. (c) Number of events each year, colors indicate the category in which they are. When an event spans over 2 years it is allocated to the year where the maximum SST anomaly falls. (d) ICEN values averaged yearly (blue) and number of days affected yearly by MHWs in the coastal domain (orange). The figure was created using Matlab R2020b (https://matlab.mathworks.com/).
