Meteorologists at’s nationwide Weather service have always monitored the problems of the setting that influence the weather, yet over time the devices they use has actually changed. As technology advanced, ours scientists began to use an ext efficient devices to collect and also use additional data. These technological advances enable our meteorologists to make far better predictions faster than ever before before.

1. Doppler radar

You are watching: Weather information collected by meteorologists at specific locations


Doppler Radar is the meteorologist’s home window into observing significant storms. V 159 radar towers across the unified States,’s nationwide Weather service has comprehensive coverage of the continent U.S. And also partial coverage of Alaska, Hawaii, Puerto Rico and also Guam. Doppler radar detects all species of precipitation, the rotation of thunderstorm clouds, airborne tornado debris, and also wind strength and also direction.Learn much more about radar

2. Satellite data


Weather Satellites monitor earth from space, collecting observational data our researchers analyze. operates three types of weather satellites. Polar orbiting satellites orbit the earth close to the surface, taking 6 or seven in-depth images a day. Geostationary satellites remain over the same ar on earth high above the surface ar taking photos of the entire planet as frequently as every 30 seconds. Deep an are satellites face the sun to monitor an effective solar storms and room weather. likewise uses data native satellites operated by various other agencies and countries.Learn more about’s weather satellites



ANWS weather balloon fitted with a radiosonde launches in Bismarck, north Dakota, on June 24, 2017. (

Radiosondes space our primary source of upper-air data. At the very least twice every day, radiosondes are tied come weather balloons and also are introduced in 92 locations across the unified States. In its two hour trip, the radiosonde floats to the upper stratosphere where it collects and also sends ago data every 2nd about wait pressure, temperature, loved one humidity, wind speed and also wind direction. During severe weather, we normally launch weather balloons an ext frequently to collect extr data around the storm environment.Learn much more about weather balloons and also radiosondes

4.Automated surface-observing systems


ASOS (automated surface ar observing systems) constantly monitor weather problems on the Earth’s surface. An ext than 900 stations across the U.S. Report data around sky conditions, surface ar visibility, precipitation, temperature and wind approximately 12 times an hour. Nearly 10,000 volunteer NWS participating Observers collect and administer us additional temperature, snowfalland rainfall data. The observational data our ASOS and volunteers collect are crucial for boosting forecasts and also warnings.Learn much more about ASOS



this aren’t vending machines: They room supercomputers the collect, procedure and analysis billions of observations from weather satellites, weather balloons, buoys and surface stations from about the world. (

See more: " Through The Fire And Flames Sheet Music Theory Analysis, Through The Fire And Flames’s Weather and Climate work Supercomputer device (WCOSS) is the backbone of modern forecasting. With 5.78 petaflop computer capacity that can procedure quadrillions of calculations per second. Ours supercomputers are virtually 6 million times more powerful than your average desktop computer. Observational data accumulated by doppler radar, radiosondes, weather satellites, buoys and also other instruments are fed into computerized NWS numerical estimate models. The models use equations, follow me with new and past weather data, to provide forecast guidance come our meteorologists.Learn much more about’s supercomputers


AWIPS (’s progressed Weather information Processing System) is a computer system processing system that combines data from every the vault tools into a graphical interface that our forecasters use to analysis data and prepare and also issue forecasts, watches, warnings. This mechanism uses supercomputers to procedure data from doppler radar, radiosondes, weather satellites, ASOS, and other resources using models and also forecast accuse products. After meteorologists prepare the forecasts, AWIPS generates weather graphics and hazardous weather watches and also warnings. Every this help our meteorologists create an ext accurate forecasts and also faster than ever before.Learn an ext about AWIPS
