Tornado Wind Field Reconstruction
Project Description
This project, titled Reconstruction of near-surface tornado wind fields from forest damage patterns in complex terrain and funded by the National Science Foundation, combines observed forest damage in complex terrain with simulated vortices in an effort to reconstruct the near-surface wind field during the passage of two tornadoes that occurred as part of the 27 April 2011 tornado outbreak across the southeastern U.S. The project began with aerial photographs and ground surveys of tornado damage in the Great Smoky Mountains National Park and the Chattahoochee National Forest.
