Oblack, Rachelle. Most damage from hurricanes comes from flooding and storm surge. These include a rotating, funnel-shaped cloud; an approaching cloud of debris; or a loud roar. Spatial analysis of tornado touchdown locations reveals several spatial relationships with regard to cities, population density, land use classification, and topography. This gives meteorologists a high-degree of confidence a damaging tornado is on the ground. From April 25 to 28, the Super Outbreak struck the southeast of the United States. Another way we currently detect tornadoes is with dual-polarization radar technology which allows organizations like the National Weather Service to see debris. That would be Texas, which averages 125 tornadoes every year. They studied the tornadoes damage in depth by comparing historical images to aerial photographs taken after the events.
