Meteorologists rely on which data source for hurricane predictions?

• A. Forecast models
• B. Ground weather stations
• C. Weather balloons
• D. Satellites

Answer: (D)

Hurricanes are eyes-wide over oceans, where ground observations are sparse. Satellites provide the most comprehensive, real-time data coverage of these storms, making them the most important source for forecasts. They give multiple, complementary measurements: visible and infrared imagery shows the storm’s structure and organization, infrared reveals cloud-top temperatures that indicate where convection is strongest, and microwave sensors can see rainfall and wind patterns through clouds. Scatterometers and other instruments estimate surface winds and sea-surface temperatures, which strongly influence hurricane development. All of this information is fed into forecast models to predict where the storm will go and how strong it might become. Ground stations and weather balloons are useful but limited over open oceans, so satellites are critical for accurate hurricane predictions.
