Sea level extremes and compounding marine heatwaves in coastal Indonesia

Nov. 3, 2022

Low-lying island nations like Indonesia are vulnerable to sea level Height EXtremes (HEXs). When compounded by marine heatwaves, HEXs have larger ecological and societal impact.

Modulation of ENSO teleconnections over North America by the Pacific decadal oscillation

Nov. 3, 2022

We use 5 large ensembles to show that a positive PDO enhances winter and spring El Niño temperature and precipitation teleconnections and diminishes La Niña teleconnections over North America.

El Niño Impacts in North America Depend Partly on North Pacific Ocean

Oct. 20, 2022

When winds relax and water temperatures rise in the central and eastern tropical Pacific Ocean during an El Niño, more rain tends to fall over the southwestern United States and northern Mexico.

Ocean currents have sheltered the Galápagos from global warming. Now it’s time to protect them

Oct. 20, 2022

While most of the world’s oceans are warming due to climate change, a new CU Boulder study explains how the waters around the Galápagos Islands are staying cool and getting colder.

Evaluation of Polar Winter Mesopause Wind in WACCMX+DART

Oct. 3, 2022

This work evaluates zonal winds in both hemispheres near the polar winter mesopause in the Whole Atmosphere Community Climate Model (WACCM) with thermosphere-ionosphere eXtension combined with data assimilation using the Data Assimilation Research Testbed (DART) (WACCMX+DART).

Anthropogenic aerosol and cryosphere changes drive Earth’s strong but transient clear-sky hemispheric albedo asymmetry

Oct. 3, 2022

A striking feature of the Earth system is that the Northern and Southern Hemispheres reflect identical amounts of sunlight.

Cloud adjustments from large-scale smoke–circulation interactions strongly modulate the southeastern Atlantic stratocumulus-to-cumulus transition

Oct. 3, 2022

Smoke from southern Africa blankets the southeastern Atlantic Ocean from June to October, producing strong and competing aerosol radiative effects.
