What Is a Heat Dome and How Does It Form?
September 16, 2024 by Julia Greenfield
Extreme heat events are becoming increasingly common across the globe, especially in regions like the United States. These weather phenomena pose serious risks to both humans and the environment.
One of the most alarming occurrences linked to these events is the emergence of “heat domes,” which can drastically elevate temperatures for extended periods.
Being fully aware of the mechanics and impacts of heat domes is crucial as we face the challenges of a warming planet.
What Is a Heat Dome?
A heat dome is a weather phenomenon that occurs when a region of high-pressure atmospheric conditions traps warm air over an area. This results in prolonged periods of extreme heat, often lasting for days or even weeks.
Picture placing a lid over a boiling pot of water – the steam has nowhere to escape, causing the water to get hotter and hotter.
Similarly, a heat dome acts like a lid on the atmosphere, trapping hot air close to the ground and preventing cooler air from entering the region.
Unlike typical heatwaves, which may last for shorter durations and move as weather systems shift, a heat dome can persist and linger, intensifying the heat.
The high-pressure system keeps the warm air stagnant, making it feel more oppressive over time. This can significantly impact not only temperature but also air quality, leading to health concerns for those exposed to these conditions for prolonged periods.
