Error Correction Means California’s Future Wetter Winters May Never Come
California and other areas of the U.S. Southwest may see less future winter precipitation than previously projected by climate models, according to new research that corrects for a long-standing model error: the double-ITCZ bias.
Uniform Ocean Warming Dominates Wet California Winters
New research shows that a warmer ocean strengthens the North Pacific westerly jet stream, steering more storms toward California.
Soil Moisture History Influences Soil Carbon Dynamics
Research shows that previous drought and flooding conditions strongly influence soil respiration and carbon composition.
Eastern North Atlantic Measurements Characterize Aerosol Particles and Their Sources
Researchers used instruments in an airborne lab to characterize aerosol particles and their sources over the remote Eastern North Atlantic.
Identifying Traits that Control Tropical Tree Species’ Moisture Needs
An analysis of Panamanian forests found two different sets of correlating hydraulics traits in tropical trees.
Fungus That Tastes Just Right
PNNL researchers are forming a clearer picture of how plant matter is transformed in the microbial gardens created by leaf-cutter ants.
Exploring Aerosol Sources in the Southern Great Plains
Field campaign data shows that biologically-derived emissions largely control the formation of organic aerosol in the Southern Great Plains.
Observations Show a Seasonal Delay of Tropical Rainfall
An observed delay in the onset of tropical rainfall from 1979 – 2019 supports a hydrological sign of global warming seen in projections of the future from models.
