Fig. 1: Global distributions of annual average heatwave metrics and differences for lake heatwaves (LHWs) and atmospheric heatwaves (AHWs).
From: Lakes are experiencing more severe heatwaves than the atmosphere
a Annual averages of heatwave frequency, b accumulated heatwave days, c heatwave intensity, d reoccurrence period, e cumulative heatwave indices (CHI), and f cumulative heat index among climatic zones (CHIP). The maps show the differences between LHWs and AHWs, and the circular charts display each metric for LHWs and AHWs on each continent. Blue and light blue show annual means; error bars represent the upper and lower bounds of 95% confidence intervals (AF: Africa, NA: North America, SA: South America, AS: Asia, EU: Europe, OC: Oceania).
