922 - What causes heatwaves, and why are they dangerous?

A heatwave is when the temperature stays really high for a few days in a row. This happens when:

1. A high-pressure system (like a big dome of air) settles over an area, trapping the hot air underneath.
2. The heat from the sun gets stuck under the dome, making it even hotter.
3. Winds can blow hot air from other places to add to the heat.

Heatwaves are dangerous because:

1. They can make people, especially the elderly and young kids, feel really sick from dehydration (not having enough water in their body).
2. The heat can cause people to get heatstroke, which can be life-threatening if not treated fast.
3. Heatwaves can also cause power outages, as people use more electricity to stay cool with air conditioners.
4. They can kill plants and animals, and even cause wildfires.

So, it's essential to stay cool, drink plenty of water, and follow the advice of grown-ups during heatwaves.
