What it takes to recover from drought
Using a combination of satellite imagery, machine learning and land surface supercomputer models, scientists have discovered the factors that determine how long it takes a place to fully recover from a drought. According to a study published today in Nature, post-drought temperatures and ongoing precipitation levels once the rains return heavily influence a region's rebound.
Why it matters: The factors that most determine drought recovery were largely unknown. Now, scientists may be able to better account for how long it takes to bounce back— and the conditions that can lead to more droughts — in climate change models.
