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.

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.

Internal variability is the dominant cause of projection uncertainty of Arctic sea ice in the short and medium term.

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.

CU Boulder Today spoke with Karnauskas about hurricane seasons, Hurricane Ian and what the rest of the 2022 season might look like.

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).

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

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