What is a Heat Dome? The Jet Stream Trap Behind Dangerous Heat Waves [SxGHhNrOHuV]
Why do meteorologists call some heat waves “heat domes”? In this Untamed Skies explainer, we go beyond the buzzword and show how a heat dome actually forms in the atmosphere. A heat wave is the impact — days of dangerous, abnormal heat. A heat dome is the pattern that can cause it: a large ridge of high pressure aloft that traps, compresses, and reinforces heat near the surface. We break down the science step by step: how warm air expands a vertical column of air; why geostrophic wind increases with height; how the jet stream forms; why a ridge in the jet stream is really a dome in 3-D; and how blocking patterns like omega blocks can make extreme heat last for days. You’ll also learn what makes a heat wave especially dangerous — humidity, warm nights, dry soils, stagnant air, urban heat, and lack of overnight relief — plus how heat domes finally break down.
