Flash drought

40:. The term "flash drought" was coined to describe the rapid onset and intensification of drought conditions, which set it apart from other, more conventional drought types that develop over longer periods. Early research focused on understanding the unique characteristics and drivers of flash droughts, while more recent studies have explored their impacts on agriculture, ecosystems, and water resources. 27:
characterized by its rapid onset, intensification, and severity over a relatively short timescale, usually within a few days or weeks. This concept has evolved during the last decade as researchers have become more interested in understanding and mitigating its impacts. Flash droughts differ from
63:, can provide valuable information on the development and progression of flash droughts. Remote sensing data can be used to assess the rapid response of ecosystems to flash droughts by analysing multiple ecological metrics derived from satellite observations. These metrics, such as 28:
other drought categories such as meteorological, hydrological, agricultural, ecological, and socioeconomic droughts, in that they develop and intensify more quickly, posing unique challenges for monitoring, prediction, and mitigation.
