Why is weather forecasting important?

Planning activities

Planting and harvesting crops

Protect livestock

Scheduling flights

Page 3: Weather Prediction

Saves lives

Saves property

One third of the money that people spend in the US is at least partially dependent on weather. This equals three trillion dollars.

Weather Balloons

Filled with helium or hydrogen, they are launched twice a day from around the world.

They record temperature, pressure, humidity and wind speed at different heights in the atmosphere.

Page 12: Weather Prediction

Satellites Satellites allow

meteorologists to see what the earth and clouds look like from space.

This way, forecasters can see how the atmosphere is behaving.

Page 13: Weather Prediction

Global Circulation

Basic air movement patterns

Lots of variation within these large zones

Page 14: Weather Prediction

RADAR

RAdio Detection And Ranging

Doppler detects what type of

precipitation is inside a cloud

Tracks movement (rotation inside, look out for tornadoes)

Predicts destination of cloud

Page 15: Weather Prediction

Supercomputers

Puts collected data onto maps

Calculates forecasts

More powerful = More accurate
