3 VORTEX2 involves a team of nearly one hundred people, many of them scientists. They are using radars and other equipment to learn more about how, why and where tornadoes form. The team is using forty cars and trucks to chase tornadoes, dropping measuring instruments in their paths. In addition, unmanned aircraft are collecting information from inside storms. The project costs more than eleven million dollars. Most of the money is coming from America's National Science Foundation. The first Vortex project took place in nineteen ninety-four and nineteen ninety-five. The results helped scientists better understand supercells. They are the severe thunderstorms that produce the most deadly and destructive tornadoes. This time, scientists hope to learn more about the formation, wind speed and shape of tornadoes. The study is to continue through June thirteenth. A second part of the study is planned for early next year. You can follow reports from scientists on the project at tornadoscientists.blogspot.com.
