An index that better captures El Niño-Southern Oscillation effects shows that Pacific tropical cyclones are more predictable than previously thought.

Study addresses shortcomings in global multiscale model storm simulations.

Atmospheric rivers that make landfall on the U.S. West Coast show broad increases in size and intensity with warmer local sea surfaces.

A new method separates climate responses initiated from atmospheric changes from those due to changing ocean circulation.

Experiments show fresh organic aerosol readily mix and mingle but remain separated as they age; results inform model assumptions about particle growth.

Floodplain inundation simulations shed light on flood generation mechanisms and the increasing role of extreme rainfall.

Machine learning applied to model cloud-cloud interactions traditionally absent in global climate models.

Atmosphere model errors in this region originate from their own limitations rather than lack of air–sea coupling.

Aerosols, El Niño, and sea surface temperature over the northern Gulf of Mexico influence variation.

New analysis assesses the realism and biases of tropical cyclones at various resolutions in E3SM.

Information extracted from a variety of atmospheric observations can correct the behavior of a model and improve simulated clouds.

A small collection of naturally interacting soil microbes could enable new studies of community interactions and metabolism.

Miscanthus and switchgrass are promising alternatives to traditional annual crops.

A new study provides insights on the location of forcing that yields the optimal cooling effect.

New research improves chemical understanding of how ultrafine atmospheric particles grow into climatically active sizes.

Community Land Model 5.0 can represent how irrigation influences water, carbon, and nitrogen budgets throughout a highly managed semiarid watershed.

Aerosol treatments in E3SM affect clouds, heat reflected to space, and Earth’s snow-or-ice-covered surface.

Ocean engineer Molly Grear leads Triton Field Trials research studying methods to detect electromagnetic fields associated with marine energy devices.

Researchers created an open database for soil-atmosphere greenhouse gas flux data.

Emulators—algorithms that fill data gaps—are traditionally used to project average temperatures and precipitation. This work shows that efficient emulators can substitute for costly simulations over a wide range of extreme indices.
