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
