The topic of “Flash Drought” is rapidly gaining attention within both the research and drought management communities. However, there is not a universally accepted definition or criteria for “flash drought,” despite recent research that has called for the research community to adopt the principle of rapid-intensification of drought conditions. Joel Lisonbee, Molly Woloszyn, and Marina Skumanich with the CPO-led National Integrated Drought Information System (NIDIS) developed a literature review to synthesize the research to date and provide a basis for future research on the topic. Specifically, the review focused on documenting the range of definitions of “flash drought” being proposed in the research community.
The study found that the term first appeared in the peer-reviewed literature in 2002, and by 2020 has become an area of active research. Within that 18-year span, “flash drought” has been given 29 general descriptions, and 20 papers have provided measurable, defining criteria used to distinguish a flash drought from other drought. Of these papers, 11 distinguish flash drought as a rapid-onset drought event, eight distinguish flash drought as a short-term or short-lived, yet severe, drought event, and one considers flash drought as both a short-lived and rapid onset event. Of the papers that define flash drought by its rate of onset, the rate proposed ranges from 5 days to 8 weeks. The paper was published in the Journal of Applied and Service Climatology by the American Association of State Climatologists.

MISSION: The Climate and Fisheries Adaptation Program (CAFA) supports targeted research to promote sustainable management, adaptation and resilience of the nation’s valuable fish stocks and fisheries-dependent communities in a changing climate. By bringing together NOAA scientists with the academic community, other federal agency scientists, non-governmental organizations and key fisheries stakeholders, CAFA addresses priority needs for information and tools identified in the 2015 NOAA Fisheries Climate Science Strategy, Fisheries Regional Action Plans, U.S. National Climate Assessment, and other sources.
ISSUE: Healthy and productive fisheries are a significant component of the U.S. economy. Commercial and recreational marine fisheries generate over $200 billion in economic activity and support more than 1.8 million jobs annually. (FEUS 2016) Reliant and sustainable fisheries also support working waterfronts and coastal communities, provide opportunities for commerce, are tied to rich cultures, and help meet the growing demand for seafood across the U.S. and the world.
Climate variability and change are having increasing impacts on fish stocks, fisheries, and marine ecosystems in the U.S., and the impacts are expected to significantly increase with continued climate change. The changing climate and ocean conditions (e.g. warming oceans, extreme events, changing currents and stratification, coastal precipitation, coastal inundation, etc.) directly and indirectly affect marine ecosystems including the abundance, distribution, and productivity of fish stocks that support economically important fisheries. Sustainable fisheries management requires an improved understanding of how climate, fishing, and other stressors interact to affect fish stocks (including their habitats and prey), fisheries and fishing‐dependent communities.
PROGRAM HISTORY: The Office of Oceanic and Atmospheric Research (OAR) Climate Program Office, and the National Marine Fisheries Service (NMFS) Office of Science and Technology launched a partnership in 2014 to advance understanding of climate‐related impacts on fish or other species that support economically important fisheries and fishing communities. The partnership originated through the former Coastal and Ocean Climate Applications (COCA) Program and in 2021 was renamed the Climate and Fisheries Adaptation (CAFA) Program as part of the OAR/CPO Adaptation Sciences Program.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
