American and European Heatwaves During Summer 2019
The summer of 2019 was marked by above average, and record-breaking warm temperatures around the globe. Heatwaves, defined here as at least three consecutive days where daily-mean temperature exceeds the 90th percentile, were a common occurrence in the Northern Hemisphere, particularly across Europe and the United States. The Modern Era retrospective Analysis for Research and Applications, Version 2 (MERRA-2) is a tool that can be useful for such studies.
