The High-Tech Drones Tracking the World’s Most Dangerous Storms | WSJ

As storms begin to batter the East and West coasts, officials rely on NOAA to predict storm paths and track hurricanes. But NOAA doesn’t just use satellites – it also uses drones to track storms.

Gliders are torpedo-shaped drones that dive underneath the ocean’s surface to track water temperature. Saildrones track what’s happening on the surface of the ocean including wave height, wind speed and salinity. Aerial drones can be launched directly into the eye of a hurricane to give a wealth of new data about how these storms are intensifying.

WSJ explains the tech behind these three important drones and looks at how NOAA uses the data to predict storms.
