Thunderstorms

Thunderstorms are types of storms that have thunder, lightning, and rain. Lightning is a BIG flash of light in the sky. Thunder is a loud sound that happens right before lightning strikes.

Thunderstorms can happen during the day or at night.

What causes thunderstorms?

1. -Moisture, or wetness in the air caused by water. Makes clouds and rain.
2. -Unstable air, or air that keeps moving. Needs to be warm and can rise fast.
3. -Lift comes from fronts, sea breezes, or mountains.

Tornadoes

Tornadoes are columns of air with fast and strong winds that rotate, or turn, in the sky. They happen during a thunderstorm. They are so strong that they can carry houses, cars and trees.

How do tornadoes form?

They come from thunderstorms. They need moist and warm air from Mexico, and cool dry air from Canada.

When those two types of air meet, they form a funnel of the tornado. A funnel cloud is a column of air that does not touch the ground. Once it does touch the ground, it is now a tornado.
