Web2 days ago · How Do Tornadoes Form? The Short Answer: A tornado forms from a large thunderstorm. Inside thunderclouds, warm, humid air rises, while cool air falls--along with rain or hail. These conditions can cause spinning air currents inside the cloud. What we do: NSSL developed the WSR-88D Mesoscale Detection Algorithm to analyze radar data and look for a rotation pattern meeting specific criteria for size, strength, vertical depth, and duration. A mesocyclone is usually 2-6 miles in diameter, and is much larger than the tornado that may develop … See more What we do: NSSL's On-Demand web-based tool helps confirm when and where tornadoes have possibly occurred by mapping circulations on Google Earth satellite images. NWS forecasters can quickly review … See more NSSL engineers and scientists have adapted phased array technology, formerly used on Navy ships for surveillance, for use in weather forecasting.
