Heat domes form under persistent high-pressure ridges in the atmosphere. These systems compress the air beneath them, causing surface temperatures to rise sharply. The trapped heat creates a feedback loop, further intensifying the heating over time.
The jet stream—a fast-flowing air current—shifts northward during the summer months. This shift influences where and how long heat domes persist. Changes in the jet stream can either anchor a heat dome in place or help dissipate it.
GAAM tracks the strength and position of the jet stream and is considered one of the best indicators for predicting heat dome formation and movement. It helps identify regions most vulnerable to extreme heating events.
Extended heat dome events can severely affect major crops such as corn, soybeans, and wheat. These disruptions impact agricultural cycles and global food markets, leading to significant economic losses due to reduced yields and price fluctuations.
Heat domes exacerbate soil dryness and accelerate water evaporation, increasing the risk of droughts. These dry conditions often trigger wildfires, causing widespread ecological damage, economic loss, and health hazards.
Unlike large-scale phenomena such as El Niño or the polar vortex, which can be forecast weeks in advance, heat domes are harder to predict accurately. This unpredictability poses challenges for early warning and disaster preparedness systems.
Extreme heat from these events places immense pressure on urban infrastructure and energy systems. Cities, which retain heat due to concrete and asphalt surfaces, experience higher temperatures, while power grids struggle to meet the surge in cooling demands.
