"description": "El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean causing an increase in sea surface height because of thermal expansion.
This visualization, created using a sea surface height anomaly product available from the Copernicus Marine Service shows sea surface height anomalies (SSHA) from January 1, 2022 through February 7, 2024. The maps have been processed to highlight the interannual signal of SSH, i.e., the mean signal, seasonal signal, and the trend have been removed. Red and orange shades indicate high sea surface heights relative to the reference state, while blue and green shades indicate sea surface heights lower than the reference state. Neutral conditions appear yellow.
A statement issued by the NOAA Climate Prediction Center on February 8, 2024, states that \"A transition from El Niño to ENSO-neutral is likely by April-June 2024 (79% chance), with increasing odds of La Niña developing in June-August 2024 (55% chance).\"",
