This project focuses both on spray icing modelling and simulation as well as on risk-informed decision-making and decision analysis for scenarios associated with spray icing risks. This multi-faceted, multi-disciplinary research project offers a novel approach to furthering the current knowledge regarding spray icing, helping to develop a holistic perspective to understanding and meeting spray icing-concerned stakeholder needs. To this aim, we modify and refine existing spray icing models for prediction of spray-icing occurrence, its rate, and severity, and develop a probabilistic framework for long-term forecasting of spray icing climatology. Tabletop exercises will also be conducted to simulate various spray icing scenarios, during which participants are able to use different spray icing-related information to make risk-informed decisions. We will also develop an interactive platform for crowdsourcing field observations and communicating spray icing risk assessments.
