Uncertainty pervades the prediction and experience of hazardous weather. It emerges in the observations of weather, the development of weather models, the construction and communication of forecasts, the interpretation of forecasts and perceptions of weather risks, and the complex process of responding to and recovering from hazardous weather. The uncertainty associated with meteorological processes and our knowledge of them is commonly considered and studied. Yet, there are myriad profound types of ambiguity that emerge, interact, operate, and propagate throughout the life cycle of hazardous weather events that are far less understood. This panel discussion will highlight experts from the social sciences to examine nonmeteorological types of ambiguity that arise from social, cultural, political, ethical, or other variables and become inferred in understandings of a forecast or warning, embedded in perceptions of risk, calculated into decisions, or imbued by context.
