Every year the US is home to up to 1200 tornadoes, often with disastrous damage. NOAA (The National Oceanic and Atmospheric Administration) publishes regional warnings of tornadoes. Due to the current data situation, however, tornadoes are only discovered late, thus the warning time is often not more than thirty minutes. In order to make more accurate predictions, Meteomatics was assigned to gather information on temperature and wind in the planetary boundary layer during the flight of the Meteodrones. Meteomatics has completed more than 130 soundings with the Meteodrones in Oklahoma. The collected data will be assimilated in a model that enables NOAA to forecast thunderstorms and tornados more precisely. An innovative project, which the SRF has summarized in a radio report including an interview.
