13 小时之前 · El Niño (La Niña) is a phenomenon in the equatorial Pacific Ocean characterized by a five consecutive 3-month running mean of sea surface temperature (SST) anomalies in the Niño 3.4 region that is above (below) the threshold of +0.5°C (-0.5°C).

2024年3月20日 · ENSO is a natural phenomenon arising from coupled interactions between the atmosphere and the ocean in the tropical Pacific Ocean. Changing sea surface temperatures alter rainfall and surface winds, which in turn alter ocean currents and sea surface temperatures.

These plots show current values of various indices vs. seven events since 1948. A multi-variate index of ENSO which uses SST, winds, SLP, and OLR. It is calculated using the JRA55 reanalysis dataset and the NCEI OLR. Produced at NOAA PSL. SST anomalies averaged over the NINO4 region 5°North-5°South; 160°East-150°West (western most of Niño indices).

Datasets Useful for ENSO Research Sea Surface Temperature (SST) Gridded SST datasets are available for monthly means and for daily. Values can be mean or anomalies. Gaps usually exist in SST dataets both in space and time. Different datasets use different models to fill in gaps.

Synopsis: ENSO-neutral is favored to develop in the next month and persist through the Northern Hemisphere summer (62% chance in June-August 2025). During February 2025, below-average sea surface temperatures (SSTs) weakened in the …

2005年12月12日 · SST Niño Regions - Graphical depiction of the regions (i.e. "NINO Boxes") most commonly used in the diagnosis and forecast of El Nino. Other El Niño Links - Links to the most informative El Niño/La Niña links on the web.

Beginning in mid-March 2024, mostly near-to-below-average sea surface temperatures (SSTs) emerged in the eastern Pacific and expanded westward. Since early December 2024, below-average SSTs persisted across the central Pacific Ocean. Since early February 2025, SST anomalies increased across the central and eastern Pacific.

2022年1月31日 · Sea surface temperature (SST) variability of El Niño–Southern Oscillation (ENSO) underpins its global impact, and its future change is a long-standing science issue. In its sixth assessment,...

2012年10月11日 · The El Niño–Southern Oscillation (ENSO)-like variability of various parameters and indices (e.g. sea surface temperature (SST)) is explored, by employing the last six decades of data on a global scale. We found that the ENSO signal in the SST field extends over tropics and subtropics, becoming maximum around 30° N and 30° S.
