Title: Heat Wave Characteristics in 50 Large U.S. Cities, 1961-2017
Abstract: These maps show changes in the number of heat waves per year (frequency); the average length of heat waves in days (duration); the number of days between the first and last heat wave of the year (season length); and how hot the heat waves were, compared with the local temperature threshold for defining a heat wave (intensity). These data were analyzed from 1961 to 2016 for 50 large metropolitan areas. The size of each circle indicates the rate of change per decade. Solid-color circles represent cities where the trend was statistically significant.
Purpose: These data were created to be used for the U.S. Environmental Protection Agency's Climate Indicators website.
