A shift in ENSO is causing worse prediction skill

Despite major progress in monitoring and understanding the El Nino-Southern Oscillation (ENSO), an alternating climate pattern of abnormally warm and cool ocean temperatures across the tropical Pacific, scientists’ ability to predict it has not shown steady improvement over the past few decades. Helping to solve this mystery, a new review article funded by the MAPP Program found that a shift in ENSO properties around 1999/2000 may account for the lower prediction skill.

Different forces drive storm-induced sea level spikes on U.S. East, Gulf coasts, says CPO-funded study 13 February 2020

Different forces drive storm-induced sea level spikes on U.S. East, Gulf coasts, says CPO-funded study

Using a new powerful NOAA global climate model, NOAA and partner researchers show that big spikes in daily coastal sea levels will increase in the future from the Gulf Coast to the Atlantic coast as warming progresses, but will be driven by differing forces in these two regions.

Record Breaking High Sea Levels in Hawaii Linked To El Niño? 4 February 2020

Record Breaking High Sea Levels in Hawaii Linked To El Niño?

Following the strong El Niño in 2015, Hawaii experienced record breaking high sea levels in 2017. Impacts of high sea levels include beach erosion, inundation, and failed drainage infrastructure due to saltwater blockage. The processes associated with the Hawaii sea level rise after an El Niño event have so far remained unknown.
