GREENBELT, Md., April 5 (UPI) -- Images from a NASA satellite show tornadoes that hit Dallas Tuesday were spawned by giant thunderstorms more than 8 miles high, the space agency said.
NASA's Tropical Rainfall Measuring Mission satellite provided a look at the thunderstorms in three dimensions, giving scientists data on the heights of the thunderclouds and the rainfall rates coming from them, the agency said in releasing the images Thursday.
