![]() Using a series of images from Hurricane Dorian, we’ve created this guide. But without the trained eye of a meteorologist, it can be a challenge for most people to know what to make of them. Brian Zachry, Technology and Science Branch Chief at NOAA’s National Hurricane Center in Miami, Fla.ĭuring major storms, it’s common for these images to circulate on social media and surface in news articles and on television reports. “This imagery is fundamental to determining where the storm is located, knowing what direction it’s moving, and estimating its strength,” said Dr. ![]() These measurements tell us about wind at various levels in the atmosphere, sea surface temperatures and cloud properties. ![]() NOAA’s GOES East and West satellites also show the storm’s evolution by measuring infrared and visible radiation from the atmosphere and surface in real-time. These data are converted into brightly colored pictures that reveal the structure, intensity and temperature of a storm, along with other features, such as lightning and gravity waves. It was the strongest storm on record to hit the island nation.ĭuring a hurricane, instruments on NOAA-20 and S-NPP capture data twice a day. That week, the world watched as Hurricane Dorian slammed into the Bahamas and then stalled for more than 36 hours, leaving an estimated 200 people dead and 70,000 homeless. The image above shows this remarkable storm structure from S-NPP at 3:03 am EDT on that morning. These images, caught from the NOAA-20 and NOAA/NASA Suomi-NPP (S-NPP) satellites, showed a nearly perfect circular eye inside a powerful Category-5 storm.
