Weather Prediction
Weather forecasting plays a crucial role in our daily lives, affecting activities like crop planting, livestock protection, and flight scheduling. In the U.S., about one-third of consumer spending, roughly three trillion dollars, is influenced by weather conditions. Meteorologists utilize various tools such as satellites, radars, and weather balloons to analyze atmospheric phenomena. They apply methods ranging from persistence to advanced technology and mathematical modeling. This comprehensive knowledge allows us to prepare for weather impacts, ultimately saving lives and property.

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 • Feel it in your bones
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
