Why is weather forecasting important?
Planning activities
Planting and harvesting crops
Protect livestock
Scheduling flights

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.

NOAA A governmental scientific
agency
Specializes in weather prediction
Warns of dangerous weather
Climate Research

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.

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.

Global Circulation
Basic air movement patterns
Lots of variation within these large zones

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

Supercomputers
Puts collected data onto maps
Calculates forecasts
More powerful = More accurate
