This briefing update was written by Elisabeth Gawthrop and Jacquelyn Turner. Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. Tony Barnston provides an overview of the briefing: What’s New Sea-surface temperatures in the equatorial Pacific have cooled slightly since this time last month. The SST conditions of the Niño3.4 region, shown in tweet image […]
Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. What’s New Typically, as we near the end of a calendar year, there is relative certainty about the anticipated state of the El Niño Southern Oscillation in the coming months. At this time of year, the ENSO cycle is in a less chaotic state, and […]

Tony Barnston provides an overview of the briefing: What’s New Sea-surface temperatures have remained above average in the equatorial region of the Pacific Ocean that defines El Niño events (called Niño3.4 – see tweet below). The SSTs have been above the +0.50ºC anomaly threshold that helps […]

Tony Barnston provides an overview of the briefing: What’s New Sea-surface temperatures are warming up in the equatorial region of the Pacific Ocean that defines El Niño events (called Niño3.4 – see map below). Whether they stay that way will determine if an El Niño event […]

Tony Barnston provides an overview of the briefing: What’s New After months of neutral ENSO conditions and forecasts of an upcoming El Niño event, September has brought yet another month of the same. Sea-surface temperature (SST) anomalies in the equatorial Pacific Ocean region that defines El […]

Tony Barnston provides an overview of the briefing: What’s New Sea-surface temperature (SST) anomalies in the equatorial Pacific Ocean have bounced around some since last month’s briefing, but models continue to predict an El Niño event to develop. Weekly SST anomalies in the area of the […]

The National Ocean and Atmospheric Administration’s Climate Prediction Center (CPC) increased the status of El Niño from watch to advisory, indicating that El Niño has officially arrived. The latest update, issued today by CPC and IRI, indicates a 50-60% chance of El Niño conditions persisting into the Northern Hemisphere’s summer. The update notes, however, that due to its weak expected […]
