      "The World Meteorological Organization (WMO) uses a definition that has practical utility in addressing human health impacts. It defines heatwaves as, “periods of unusually hot and dry or hot and humid weather that have a subtle onset and cessation, a duration of at least two to three days and a discernible impact on human activities” (WMO and WHO, 2015). However, this definition is not sufficient to guide National Meteorological and Hydrological Services in developing practical methods and tools for a heatwave monitoring system that would allow comparisons across regional or international borders. Common characteristics of heatwaves such as magnitude, duration, extent, severity, and timing of the event during the heat season, are often used to compare heatwave events (Global Heat Health Information Network, 2020). Heatwaves differ from warm spells. Similar to heatwaves, warm spells are defined as a persistent period of abnormally warm weather in a location. A warm spell can similarly be defined in terms of the 90th or 95th percentile of daily maximum temperature (Tmax). A warm spell occurs at any time of the year, whereas heatwaves can only occur in the warm season (WMO, 2020)."
