AbstractHydroclimate volatility refers to sudden, large and/or frequent transitions between very dry and very wet conditions. In this Review, we examine how hydroclimate volatility is anticipated to evolve with anthropogenic warming. Using a metric of ‘hydroclimate whiplash’ based on the Standardized Precipitation Evapotranspiration Index, global-averaged subseasonal (3-month) and interannual (12-month) whiplash have increased by 31–66% and 8–31%, respectively, since the mid-twentieth century.

AbstractStraight line winds (SLWs), or non-tornadic thunderstorm winds, are causing widespread damage in many regions around the world. These powerful gusts are associated with strong downdraughts in thunderstorms, rear inflow jets and mesovortices. Despite their significance, our understanding of climate change effects on SLWs remains limited.
