Weather Balloons: Storms' Secret Weapon
9 Oct
Summary
- Balloons carry instruments to measure atmospheric data.
- Data helps meteorologists forecast rain and storms.
- Launched from dozens of locations across the country.
Data gathered from high-altitude weather balloons is indispensable for meteorologists in predicting approaching storms and hurricanes. These balloons, often filled with hydrogen and sent to approximately 100,000 feet before popping, carry instruments known as radiosondes.
These radiosondes collect critical atmospheric information, including temperature, wind speed and direction, air pressure, and moisture levels. This data is then assimilated into sophisticated computer models, which are essential for generating accurate weather forecasts and tracking severe weather events like hurricanes.
Launched twice daily from dozens of sites across the country, with increased frequency during significant weather events, these balloons serve as an early warning system. The information they provide allows for timely preparation and more precise tracking of storms, as demonstrated during the approach of Hurricane Isaias.
