“…A few other indicators, not listed above, include: crop condition data, cloud cover, 10-m wind speed, dewpoint depression (Otkin et al 2013), a rapid change index for ESI, the SPI and total column soil moisture (Otkin et al 2015a), a vegetative drought response index, dew point temperature (Otkin et al 2016), a lower tropospheric humidity index, a convective triggering potential-similar to CAPE (Gerken et al 2018) Kimball et al 2019;and He et al 2019). While not an exhaustive list, these papers demonstrate that flash drought can be looked at in a myriad of ways, using various indicators within the climate system, without necessarily setting terms or thresholds to diagnose a flash drought event (Zhang et al 2020).…”

The topic of "Flash Drought" is rapidly gaining attention within both the research and drought management communities. This literature review aims to synthesize the research todate and provide a basis for future research on the topic. Specifically, our review is focused on documenting the range of definitions of "flash drought" being proposed in the research community. We 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 while eight distinguish flash drought as a short-term or short-lived, yet severe, drought event and one paper considers flash drought as both a short-lived and rapid onset event. Of the papers that define a flash drought by its rate of onset, the rate proposed ranges from 5 days to 8 weeks. Currently, 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.

Flash droughts feature rapid onsets of soil moisture drought events and result in severe impacts and damages, especially on agricultural and ecological systems. How the ash drought regime across China varies on multitemporal scales with climate change is not fully clear yet. In this study, we extended the ash drought de nition to apply to arid regions by adding an absolute soil moisture variation criterion.Then, we detected ash drought events across China during 1981-2021 and characterized their frequency, duration, and affected area changes on seasonal, annual, and decadal scales, using soil moisture data from the European Center for Medium-Range Weather Forecasts climate reanalysis-Land. Results show that hotspots of ash droughts appeared in North China and the Yangtze River Basin.During 1981-2021, the hotspots, even nationwide, underwent signi cant increases in frequencies, durations, and affected areas of ash droughts. The increases held in the extremely high values of the frequencies and durations in the decadal comparisons. Especially, North China saw the most extensive and rapid increases. Seasonally, ash drought frequencies and durations intensi ed more during spring and autumn, and seasonal hotspots in eastern China shifted in phase with spatial patterns of soil moisture loss balanced by precipitation and evapotranspiration. Thus, ash droughts tended to amplify atmospheric aridity. These ndings on the hotspot regions and the spatiotemporal evolutions of ash droughts across China would pinpoint soil moisture responses to climate change and prepare for climate change impacts on local eco-environments.
