By studying the chemical signatures of 300-million-year-old precipitation, researchers find evidence that the supercontinent Pangea contained peaks as tall as the European Alps.
Precipitation
A New Proxy for Past Precipitation
Researchers used luminescence signals from marine sediment cores to bolster estimates of precipitation levels on land over the past 30,000 years.
Accounting for the Fact that Snow Falls Slower than Rain
When calibrating satellite observations with ground-based ones, estimated precipitation rates are improved by considering that snow takes longer to fall compared to rain.
Rainfall Kick-Starts Slow-Moving Landslides
A census of hundreds of slow-moving landslides in Northern California reveals an uptick in the number and speed of landslides in 2017, the second-wettest year on record.
Landslide Activity Ramps Up With Extreme Rainfall
An increase in activity of hundreds of slow-moving landslides during extreme wet conditions in California provides insights into the landscape response to ongoing climate change.
Congo Rain Forest Endures a Longer Dry Season
The forest’s dry season has been starting earlier and ending later for decades, making parts of it vulnerable to incursions by drought-resistant ecosystems.
One Step Closer to a Milestone in Climate Modeling
A pair of revisions to the Energy Exascale Earth System Model improves its ability to capture late afternoon and nocturnal rainfall as well as the timing and movement of convection.
Extreme Precipitation Expected to Increase with Warming Planet
A new analysis indicates that the frequency and magnitude of extreme precipitation events are expected to increase as Earth continues to warm.
Precipitation in the Tropics: A New View
The first study to simultaneously investigate precipitation and cloud structures in tropical weather systems concludes observation systems significantly overestimate the height of raining clouds.
What Climate Models Get Wrong About Future Water Availability
Models that accurately represent past and present rainfall provide more accurate projections of water availability, a new study suggests.
