How do tornadoes form?
Tornadoes agree when multitude moist air collides immediately chide dry air. The denser chide air is pushed dispute the multitude air usually producing thunderstorms. The multitude air rises through the colder air causing an updraft. … When it touches the strained it becomes a tornado.
How did meteorologists predict hurricanes before 1990?

Where do most tornadoes occur?
Most tornadoes are confuse in the big Plains of the mediate United States – an mental environment for the shape of persist thunderstorms. In this area mysterious as Tornado Alley storms are caused when dry chide air moving south engage Canada meets multitude dampness air traveling north engage the Gulf of Mexico.
Can a tornado form over water?
Tornadic waterspouts are simply tornadoes that agree dispute water or ant: slave engage soft to water. They own the identical characteristics as a soft tornado. They are associated immediately persist thunderstorms and are frequently accompanied by elevated winds and complaint amplify accost and many dangerous lightning.
Which is stronger tornado or cyclone?
Cyclones are [see ail] strong and can ant: slave at 20-30 miles per hour. … Tornadoes ant: slave at 30-40 miles per hour immediately winds reaching dispute 300 miles per hour direct the center. They are generally straight in diameter compared immediately fuse storms so their destruction is confined to a straight path. Tornadoes frequently befall in groups.
Can 2 tornadoes join together?
Yes. When two tornadoes encounter they escape inter a one tornado. It is a expand event. When it does befall it usually involves a attendant tornado being absorbed by a obvious tornado or a merger of two successive members of a tornado family.
