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:
- A high-pressure system (like a big dome of air) settles over an area, trapping the hot air underneath.
- The heat from the sun gets stuck under the dome, making it even hotter.
- Winds can blow hot air from other places to add to the heat.
Heatwaves are dangerous because:
- They can make people, especially the elderly and young kids, feel really sick from dehydration (not having enough water in their body).
- The heat can cause people to get heatstroke, which can be life-threatening if not treated fast.
- Heatwaves can also cause power outages, as people use more electricity to stay cool with air conditioners.
- 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.
