Robotic Weather Planes Could Improve Weather Forecasts

Robotic Weather Planes Could Improve Weather Forecasts 

 Small, unmanned aerial vehicles, such as this 18-kilogram Boeing ScanEagle, could provide more precise data about weather systems.

Weather forecasters may not have the best reputation for accuracy, but with today’s computational modeling, it’s possible to make pretty reliable weather predictions up to 48 hours in advance. Researchers at MIT, however, believe that autonomous aircraft running smart storm-chasing algorithms could get that figure up to four days. Better weather forecasting could help farmers and transportation authorities with planning and even save lives by providing earlier warnings about storms and severe weather, says Jonathan How, principal investigator at MIT’s Department of Aeronautics and Astronautics.
