Three characteristics prone to tornado activity

From thunderstorms
Follows the jet stream
Follows criollos effect
Form whrn warm, humid air collides with cold, dry air

1. Intense thunderstorms: Tornadoes often form within severe thunderstorms that have strong updrafts and rotating air.

2. Jet stream: Tornadoes are more likely to form in areas where the jet stream, a fast-moving band of air high in the atmosphere, is present. The jet stream can create wind shear, which is a key ingredient for tornado formation.

3. Colliding air masses: Tornadoes are more likely to form when warm, humid air from the Gulf of Mexico collides with cold, dry air from Canada. This clash of air masses creates instability in the atmosphere, which can lead to the development of tornadoes.

It is important to note that while these characteristics can increase the likelihood of tornado activity, tornadoes can still form under a variety of conditions and are not limited to these factors alone.
