Weather forecasting is a prediction of what the

weather will be like in an hour, tomorrow, or next

week. Weather forecasting involves a

combination of computer models, observations, and a knowledge of

trends and patterns. By using these methods, reasonable accurate

forecasts can be made up to seven days in advance.

Weather Predicting

How do meteorologists predictthe weather?

What is a Weather Satellite?

Primarily used to monitor the weather and climate of the Earth.

Can also monitor fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents,

etc.

What is Radar? Radar is an electronic instrument, which determines

the direction and distance of objects that reflect radio energy back to the radar site. It stands for

Radio Detection and Ranging. This is what meteorologists use to see rain or snow.

What is Doppler Radar?Doppler Radar detects precipitation intensity, wind direction and speed, and provides estimates of hail size and rainfall amounts. Doppler Radar gives forecasters the capability of providing early detection of severe thunderstorms that may

bring strong damaging winds, large hail, heavy rain, and possibly tornadoes. Combined with satellites, radar gives

forecasters the ultimate tools to provide accurate forecasts and advanced severe weather warnings.

How does Doppler Radar work?

Doppler Radar gets its name from the Doppler Effect. Have you ever listened to a train whistle as it was coming toward you? You probably noticed that the

pitch of the whistle changed as the train passed you and moved away. This change in the frequency of sound is called the Doppler Effect. Doppler Radar

measures the changes in the frequency of the signal it receives to determine the wind.

What is NEXRAD Radar? The National Weather Service has installed a new type of Doppler Radar called NEXRAD Radar. NEXRAD stands for Next Generation Radar. This radar produces many different

views of storms and rain that allows meteorologists to determine if a storm could

be severe.
