CIWRO

CIWRO gathers feedback from the emergency management and private broadcast sectors about U.S. National Weather Service (NWS) forecast and warning products. For instance, researchers designed and distributed an Oklahoma-wide survey with US National Weather Service Norman Oklahoma and Oklahoma Forestry Services to learn how emergency managers use weather information to prepare for dangerous wildfires. CIWRO scientists also ask questions about what weather information they need and if current products are meeting their needs.

The Tornado Probability algorithm (TORP) is a product that uses AI to quickly summarize radar data to determine the tornado potential of severe storms.

Developed by CIWRO, this innovative algorithm works by generating complex wind rotation calculations. TORP is designed to assist forecasters in making timely and accurate tornado warning decisions.

TORP tornado probabilities have been made available to U.S. National Weather Service (NWS) forecasters in real time, and have been successfully used to influence
warning decisions, letting forecasters easily pick out intensifying storms and gain confidence in their decision making.

CIWRO develops and maintains products to enhance the forecasting of severe weather threats up to 8 days in advance. These innovations are fully integrated in Storm Prediction Center operations and guide NWS forecasters nationwide. Sixteen CIWRO-developed tools have transitioned into SPC operations since 2021.

CIWRO researchers are on the forefront of AI advancements in the prediction of weather hazards. Warn on Forecast System - Probabilistic Hazard
Information (WoFS-PHI) updates every five minutes, meaning forecasters get rapid updates on severe-weather threats like tornadoes, hail, wind and lightning. WoFS-PHI offers forecasters probabilities that move with the storms.

In this radar image, the distinct rounded yellow polygons indicate the likelihood that an area will receive severe weather. The darker the polygon, the greater percentage chance that area will be affected. Using the PHI information, a forecaster has issued a tornado warning in red.
