Pilots routinely fly over remote stretches of ocean with almost no weather information, apart from a pre-flight briefing and updates every four hours. Yet this is where some of the worst turbulence and, as Air France Flight 447 tragically encountered on June 1, most intense weather occurs. The National Centre for Atmospheric Research (NCAR) is developing a new system that combines satellite data, weather models and A.I. to identify and predict rapidly evolving storms, enabling pilots to avoid areas of potentially severe turbulence.
