About this episode
This summer, relax and learn with Do You Really Know! It's time to learn all about the concepts, words and expressions that surround the summer season! What is a heatwave? We’re experiencing more intense and frequent heatwaves than ever before, and it’s one of the most tangible effects of climate change. These summer periods of extreme heat are a threat to the elderly, children and the poor. To meet the World Meteorological Organization’s definition of a heatwave, the period must last 5 days or longer. The daily maximum temperature must also be at least 5° higher than the average maximum temperature. This means the requirements can vary by region. Some nations have their own definition of a heatwave. For example, the UK’s Met Office uses a system called Heat Health Watch. To determine whether a heatwave is occurring, the maximum daytime temperature and minimum nighttime temperature are compared to regional thresholds. A four-level system is used to score each Local Authority area, with Level 4 being the highest. So what actually causes a heatwave then? What are the guidelines? Who has the greater risks?
