Associated Press. “Some wind farms have appeared on Doppler radar as either a tornado or a violent thunderstorm,” wrote Dirk Lammers. “The National Weather Service received a frantic warning from an emergency worker in Kansas who had access to radar images and thought he’d seen a tornado. What he actually saw was an image of wind turbines with fast moving blades.” 

This is a case where a human eye is better than a computer. The turbines can set off an automatic alert from a Doppler radar. (Wind farms built within 11 miles of a Doppler site seem to have the biggest effect.) But when a real, live weather person looks at the screen, she can tell a real tornado from a blip caused by turbines. Software can remove stationary obstacles — mountains, buildings — but there is no fix yet for removing moving turbines.

Weather people are aghast that anyone trained on reading a radar would be fooled. However, it appears that the Royal Air Force’s air traffic radars have been fooled, too.

Is It a Tornado or a Wind Turbine?

All those whirling wind turbines out there are causing havoc with weather radar, or so says the Associated Press. "Some wind farms have appeared on Doppler radar as either a tornado or a violent thunderstorm," wrote Dirk Lammers.
