Meteorologists Track Hurricanes
Tracking Hurricanes: Methods and Technologies
Meteorologists track hurricanes using a combination of advanced technologies and methods to ensure accurate forecasting and timely warnings.
1. Satellite Observations:
Geostationary satellites, such as GOES-16, provide real-time imagery of hurricanes, capturing their development and movement. These satellites orbit at the same speed as Earth’s rotation, allowing continuous monitoring of storm systems. Polar-orbiting satellites, like Suomi NPP, offer detailed atmospheric profiles and global coverage, enhancing data on temperature, humidity, and pressure.
2. Radar Systems:
Doppler radar systems measure precipitation velocity within hurricanes, helping meteorologists assess wind speeds and storm structure. The Weather Surveillance Radar (WSR-88D) is a key tool in analyzing precipitation intensity and movement. Additionally, the Hurricane Hunter aircraft, operated by NOAA and the U.S. Air Force, flies directly into hurricanes to collect in-situ data on wind speeds, pressure, and humidity.
3. Ocean Buoys and Sensors:
Buoys from networks like the National Data Buoy Center (NDBC) measure sea surface temperatures, wave heights, and wind speeds. The Deep-ocean Assessment and Reporting of Tsunamis (DART) buoys provide crucial data on sea level changes. Argo floats collect temperature and salinity data from various ocean depths, aiding in understanding the ocean’s role in storm intensity.
4. Numerical Weather Prediction Models:
Computer models such as the Global Forecast System (GFS) and European Centre for Medium-Range Weather Forecasts (ECMWF) simulate atmospheric conditions and predict hurricane paths and intensity. Ensemble forecasting, which runs multiple simulations, helps assess uncertainties and provide a range of potential outcomes.
These integrated methods enable meteorologists to track hurricanes accurately, predict their paths, and provide critical information for disaster preparedness.

Meteorologists use a variety of tools and techniques to track the path and intensity of hurricanes:
Satellite Imagery: Meteorologists analyze satellite images from geostationary and polar-orbiting satellites to monitor the development, structure, and movement of hurricanes. Satellite data provides a comprehensive view of the entire storm system.
Radar Observations: Ground-based weather radars, including Doppler radar, are used to track the location, intensity, and structure of hurricanes as they approach land. Radar can detect the storm’s eye, spiral rain bands, and wind speeds.
Aircraft Reconnaissance: Specially equipped hurricane hunter aircraft fly directly into the storm to collect critical data on wind speeds, central pressure, temperature, and other atmospheric conditions. This in-situ data helps refine hurricane forecasts.
Surface Observations: Data from weather buoys, ships, and coastal weather stations provide information on the storm’s proximity to land, wind speeds, and other measurements that help assess the hurricane’s intensity and path.
Computer Models: Sophisticated weather prediction models, which incorporate data from multiple sources, are used to forecast the hurricane’s future track, intensity, and potential impacts. These models are continuously updated as new observations become available.
Storm Surge Prediction: Meteorologists work with hydrologists to model and predict the potential for dangerous storm surge flooding, which can be one of the most destructive aspects of a hurricane.
By combining these various data sources and analysis techniques, meteorologists can closely monitor the development and movement of hurricanes, allowing for more accurate forecasts and timely warnings to protect vulnerable communities.
