Perceptions of Flash Drought in the U.S.: How do End-Users and Researchers Compare?

Defining flash drought is important not only for the development of the science but also for ensuring clear and useful early warning information to end users. In preparation for a December 2020 U.S-based workshop on flash drought, the National Integrated Drought Information System (NIDIS) and National Drought Mitigation Center (NDMC) undertook a survey of NIDIS contacts to explore how flash drought is understood within and outside of the research community. End users represented in the survey include researchers (outside of flash drought specialty), policy-makers, decision-makers, communicators, and educators and public engagement specialists, largely working within universities or federal agencies across the U.S. Flash drought researchers were asked to describe how they intend for the term “flash drought” to be interpreted when they use it. End users (whether they had heard/used the term before or not) were asked to describe what they think of when they hear the term “flash drought”. Their answers emerged into themes, including: onset/intensification, duration, drivers, impacts, seasonality, predictability, intensity, spatial scale, and uncertainty about its meaning. In this presentation, we will elaborate upon these themes, and discuss similarities and differences in how flash drought researchers and end users conceptualize flash drought.
