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.
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.
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.
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).
