More Studies, Faster Forecasting Needed To Fight Flash #Drought, Says Paper — KUNC

Drought impacted corn. Water stress can lead to insufficient water supply for cities, agriculture, and vegetation. Dry vegetation may facilitate the propagation and increase the risk of wildfires.

From KUNC (Noah Glick):

Researchers in our region are arguing for new models to better plan for a recent climate phenomenon: flash droughts. According to a new paper published in the journal Nature Climate Change, these events present new challenges for climate predictors.

Angie Pendergrass is a scientist with the National Center for Atmospheric Research in Boulder, Colorado and a co-author of the paper. She said current models are better at measuring long-term drought effects.

“There needs to be a faster timeframe that we monitor, [to] say where we are and what’s happening,” said Pendergrass. “Instead of every week, that needs to happen perhaps every few days.”

Flash droughts are short-term climate events where an area will experience a sudden and rapid escalation of drought conditions. Pendergrass said that can have big impacts on arid regions, like the Mountain West, which has some of the driest states in the nation…

“If you’re already starting out from a state that’s a little bit dry and then suddenly things get a lot drier, it can cause problems in other situations, too,” Pendergrass said.

Those problems range from agriculture concerns to water management and energy production.

“A flash drought could deplete reservoirs, affecting both water availability and hydropower generation capacity in places like the southwest United States, where water is highly managed,” the paper stated.
