What is the difference in a tornado watch and a tornado warning?

Use page 17 in the AMSTI book for help.

Tornado Watch….(red box)

• is issued when weather conditions are favorable for the development of severe thunderstorms that are capable of producing tornadoes.

• A tornado watch therefore implies that it is also a severe thunderstorm watch.

• Example of NWS tornado watch:• http://en.wikipedia.org/wiki/Tornado_watch

Tornado Warning….

• is issued when a tornado or funnel cloud has been spotted

• sometimes if there is a rotating wall cloud

• even issued if radar indicates a tornado is imminent

Wall Cloud….where strong tornadoes form

What is a Vortex?

On page 14 write the word VORTEX and put a star next to it. (hint, hint)

Let’s come up with a class definition of this word.

Vortex in clouds

Karman Vortices

Vortex in a hurricane

Dust Devil

Vortex in a waterspout

Vortex in a tornado

Small Vortex Large Vortex

Vortex in the air

Guess where this is?

Multiple Vortexes = VORITCES

Dolphins Create a Vortex

Coriolis Effect• Pressure differences tend to push winds in

straight paths.

• As air begins flowing from high to low pressure, the Earth rotates under it, making the wind follow a curved path.

• In the Northern Hemisphere, the wind turns to the right of its direction of motion. In the Southern Hemisphere, it turns to the left.

• The Coriolis force is zero at the equator. This explains why the weather is relatively calm at the equator!

• A hockey puck is launched from the north pole. As it heads south, the earth turns to the east, causing the puck to appear to deflect to the west as viewed by an earthbound observer.
