New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.
Recent advances in measurements and models are paving the way to transform fundamental understanding and simulation of ice-nucleating particles and their climate impacts.
New measurements show the macro- and microphysical characteristics of the clouds and precipitation over the data-space regions of the Southern Ocean.
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.
Vegetation response to precipitation is important for near-term weather predictability, and researchers show that such a response can occur within a few days and last up to two months.
El Niño Southern Oscillation (ENSO) predictability is examined in a new global coupled retrospective forecast ensemble for the 20th Century.
Researchers review the challenges and prospects of Earth System Models that incorporate a consistent closed energy budget.
Droughts in one region of the Amazon can lead to less moisture elsewhere, and trees may not adapt quickly enough to survive.
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.
Observational and modeling studies identify the Eastern Mediterranean and Middle East as a prominent climate change hotspot associated with weather extremes that have major impacts on society.
