Extreme weather and climate information

When hazardous weather threatens, people access multiple forms of risk information, which influences their risk assessments and responses as the threat evolves. To understand these dynamic processes, MMM researchers and collaborators qualitatively analyzed Twitter narratives produced by members of the at-risk public as Hurricane Sandy approached and affected New York City in 2012. The results provide new insights into how forecast and warning information, environmental and social cues, risk perceptions, and protective decisions interact and evolve during a hurricane threat, in the context of the complex modern information environment (Demuth et al. submitted).
