The correct answer is:

✅ High pressure systems

High-pressure systems (anticyclones) trap hot air in a "dome," causing heat waves by:

Sinking air: Compresses and heats up (adiabatic heating).

Clear skies: Allows relentless solar radiation.

Stagnant air: Blocks cooler fronts from moving in.

Duration: Can last days to weeks (e.g., 2021 Pacific Northwest heat dome).

Records: Often break all-time temperature highs.

❌ Low-pressure systems: Typically bring storms and cooler air.

❌ Cold fronts: End heat waves, not cause them.

Fun Fact: The 2003 European heat wave killed ~70,000 people due to a stuck high-pressure system. ☠️🔥

Safety Tip: Stay hydrated and avoid midday sun during heat waves! 💦🌞
