Explained simply
A heat dome is a weather pattern where a large area of hot air becomes trapped over a region, preventing cooler weather from moving in. This can last for days or weeks, creating dangerously high temperatures across a wide area that may include millions of people.
Extreme heat poses significant risks to human health, including heat exhaustion, heat stroke, and dehydration, with particular danger for elderly people and those with medical conditions. Heat waves also strain electricity systems as people use more air conditioning, and can disrupt transport and daily life across affected regions.
The scale of current weather warnings affecting more than 80 million Americans reflects how these intense heat events increasingly impact large populations simultaneously. Meteorologists have noted a concerning trend of heat domes becoming more frequent and more severe in recent years.
