The Weather Research and Forecasting Innovation Act (WRFIA) of 2017 calls for NOAA in collaboration with the United States weather industry and academia to develop a tornado warning improvement and extension program (TWIEP). Through this program, the goal is to reduce the loss of life and economic losses from tornadoes through the development and extension of accurate, effective, and timely tornado forecasts, predictions, and warnings, including the prediction of tornadoes beyond 1 hour in advance. This sessions seeks to bring together the weather enterprise (federal, private, and academia) to seek innovative solutions that will one day help the enterprise achieve its goals as stated in the WRFIA. We are asking for presenters from both the physical and social sciences to present work to advance the knowledge base of the weather enterprise and bring focus and clarity on current and future improvements in tornado warning science across all sectors.
