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.
How do you predict the weather? Clouds
Wind
Air Pressure
Temperature
Static

Ways of Forecasting
Persistence method
Trends method
Advanced Weather Prediction
Technology
Science
Math
Meteorologist Their goal is to
explain, understand, observe and forecast the Earth's atmospheric phenomena
A scientist who studies weather
Work Quickly
Tools Satellites
Radars
Weather stations
Sensors
Observers
How do you get a forecast?
Internet
Radio
TV
Almanac
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
