Whether warming increases or decreases, rain over land depends on the relationship of soil moisture, evaporation, and aridity which shape rain regimes.

An Innovative Approach to Model Complex Hurricane Flood Hazards
A new study shows that it is possible to produce regional assessments of how hurricane flood hazards change due to both evolving storm tides and precipitation rates in a warming climate.
A Theory of Squall Lines
About 50 years ago, vorticity thinking helped unveil basic properties of squall lines. Zhang now provides a closed theory, demystifying one of nature’s most important forms of convective organization.
Amazon Basin Tree Rings Hold a Record of the Region’s Rainfall
New research provides a 200-year reconstruction of interannual rainfall in the Amazon basin using oxygen isotopes preserved in tree rings in Ecuador and Bolivia.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
Why Does It Rain So Much Over Tropical Land?
Analyses of observations show that tropical land receives more rain than its fair share, owing to a proposed negative feedback that is not captured in current climate models.
Advanced Real-Time Prediction of Storms With 30-Second Refresh
A new-generation weather radar and a massive supercomputing system enables forecasts of storms refreshed every 30 seconds, a significant development in severe weather prediction.
More Accurately Modeling Rain Formation
Rain and cloud droplets are treated as distinct categories in most models yet lie on a continuous droplet size spectrum in nature. Representing them as part of a continuous spectrum improves models.
Explaining Uncertainty in Estimates of Rain Response to Warming
Humidity increases with warming. Theory and observations about how increased humidity translates into more extreme rainfall can be reconciled if attention is paid to data and methods.
Large-Scale Reforestation Efforts Could Dry Out Landscapes Across the World
The complex interactions between forests and the water cycle might end up with more rain falling in the ocean—far from a thirsty land.
