Heat Dome Quiz: How High Pressure Bakes Europe
Sinking air under a stubborn ridge of high pressure warms as it is squeezed, and this heat dome quiz explains how that creates record heat. Play 10 interactive questions on blocking patterns, the jet stream, Europe's deadly 2003 heat wave, Britain's first 40°C day, Lytton's Canadian record, tropical nights and the role of climate change.

Explanations: answer key for all 10 questions
- Q1: What is a heat dome?
Answer: High pressure trapping hot air over a region
The high acts like a lid on a pot.
- Q2: Why does sinking air under a heat dome get hotter?
Answer: It is compressed as it descends
Compression warms air without adding heat.
- Q3: What kind of skies usually come with a heat dome?
Answer: Clear and sunny
Sinking air suppresses clouds.
- Q4: Which wind pattern often helps lock heat domes in place?
Answer: A wavy, slow jet stream
Blocked patterns can stall for days.
- Q5: What is an omega block?
Answer: A pressure pattern shaped like the Greek letter omega
It can hold a high in place for a week or more.
- Q6: Which year brought a deadly European heat wave with tens of thousands of deaths?
Answer: 2003
France and Italy were hit especially hard.
- Q7: In which year did the UK first record 40°C?
Answer: 2022
Coningsby in Lincolnshire reached 40.3°C.
- Q8: Which village set Canada's temperature record in the 2021 heat dome?
Answer: Lytton, British Columbia
It reached 49.6°C and burned in a wildfire soon after.
- Q9: What is a tropical night?
Answer: A night when temperatures stay above 20°C
Warm nights stop bodies from recovering.
- Q10: What do scientists say climate change does to heat domes?
Answer: Makes extreme heat events hotter and more frequent
Attribution studies link warming to many recent records.
Heat Dome Quiz – When High Pressure Bakes the Land
A heat dome forms when a strong area of high pressure sits over a region and traps hot air. Air sinking under the high is compressed and warms, while clear skies let the sun heat the ground day after day.
Heat domes often stay in place because the jet stream becomes wavy and slow, creating blocking patterns such as omega blocks. Europe's 2003 heat wave killed tens of thousands of people, and in 2022 the UK reached 40°C for the first time.
In 2021 a heat dome over western North America brought Canada's record of 49.6°C at Lytton. Tropical nights above 20°C make heat waves more dangerous. Scientists find climate change is making such events hotter and more frequent.
