South America and southern Africa are identified as major hotspots for these droughts.
Deforestation, high temperatures, and changing precipitation patterns are key drivers.
Central Asian mountainous regions are experiencing a decrease in flash drought extent.
Improved early warning systems are needed to incorporate changing drought characteristics for better disaster preparedness.
