Fidelity of El Niño simulation matters for predicting future climate

A new study led by University of Hawai’i at Mānoa researchers, published in the journal Nature Communications this week, revealed that correctly simulating ocean current variations hundreds of feet below the ocean surface – the so-called Pacific Equatorial Undercurrent – during El Niño events is key in reducing the uncertainty of predictions of future warming in the eastern tropical Pacific.

A Weak El Nino Transitioning to La Nada

Reposted from the Cliff Mass Weather Blog Friday, February 14, 2020 A Weak El Nino Transitioning to La Nada During the past few months we have moved from near neutral conditions (La Nada) to a weak El Nino (warmer than normal temperatures in the central and eastern tropic Pacific)–providing some insights into the weather later…

Disentangling California Drought
