ENSO (El Nino Southern Oscillations)
1. ENSO - Expert Analysis and Discussion: Updated 25 September 2023
GWO Predicted 10-Months in Advance - El Niño would form by July
a. Global Weather Oscillations Inc.
As noted in the time series (from top to bottom), during the past 4-weeks the area of much warmer than normal Tropical Equatorial Pacific surface water (red in top panel) has remained very warm and has not expanded in area. This area of very warm surface water in the Eastern and Central Tropical Pacific is due to the strong upwelling of very warm subsurface water.
The much warmer than normal surface water will continue through the Northern Hemisphere winter and Southern Hemisphere summer.
This is the first El Niño to form near the South America Coast near Peru since prior to 1981. Thus, weather around the world will be much different than during the El Niño events from 1982 through 2020.
Expect ENSO El Niño conditions becoming stronger into the northern hemisphere winter - southern hemisphere summer.

b. NOAA - ENSO (El Niño - La Niña) Prediction - updated 20 September 2023
El Niño Conditions
El Niño conditions are observed.*
Equatorial sea surface temperatures (SSTs) are above average across the central and eastern Pacific Ocean.
The tropical Pacific atmospheric anomalies are consistent with El Niño.
El Niño is anticipated to continue through the Northern Hemisphere winter (with greater than a 95% chance through January-March 2024)
2. Current Conditions - Expert Analysis by GWO - Updated 20 Sept. 2023
a. Tropical Pacific Ocean Subsurface Temperatures
(down to 250 meters) - see figure 1 below
El Niño events typically develop in the Eastern Tropical South Pacific between the South American Coast and the Central South Pacific. This is called the Niño 3.4 Region.
During the period from 01 August (top panel) to 20 September 2023 (bottom panel) - it can seen that the much warmer than normal subsurface water (red) has expanded in area and is upwelling to the surface in the Eastern Tropical Pacific. Much warmer water (orange) was also upwelling to the surface across the West Central Equitorial Pacific.
A seen in the bottom panel - the subsurface water is now moderating in the Western Portion of the Equatorial Pacific - and even a patch of colder than normal (blue) is beginning to develop. This signifies that the El Niño is now likely at its strongest maturity - but will continue well into the northern hemisphere winter.

b. Surface Water Temperatures: Niño 3.4 Region
(where El Nino events typically form)
El Niño events develop in the Eastern Tropical South Pacific between the South American Coast and the Central South Pacific. This is called the Niño 3.4 Region. In 2023 it formed in the Nino 4 Region in the Extreme Eastern Tropical Pacific - first time since prior to 1981.
The surface water in the region Niño 3.4 where an El Niño typically forms - is much warmer than normal in response to upwelling of the subsurface warm water.
Although El Nino events typically occur in the Nino 3.4 region in the East Central Tropical pacific - this El Nino formed in the Nino 4 region in the Eastern Pacific off of Peru. This is the first one to form in this region since prior to 1981 and the water in this region is extremely warm - See The Spike on the Graph.
ENSO El Niño Conditions will continue through the Northern Hemisphere winter and Southern Hemisphere summer.

The panels above show much warmer than normal subsurface temperatures in (red) - warmer than normal (yellow and orange) and colder than normal (light blue to dark blue).
For an El Niño to Form - the subsurface water must warm dramatically across the Central and Eastern Tropical Pacific - and then have the warmer than normal water upwell to the surface.

For an El Niño to Form - the subsurface water must warm dramatically over the western and central Tropical South Pacific - and then move east toward South America. Once it reaches South American and upwells to the surface, an El Niño will be in place.

The Tropical South Pacific surface water temperature anomalies during the past 4 weeks from 30 August 2023 to 20 September 2023.
The yellow to red colors denote above normal warm water temperatures, the blue colors are the colder than normal surface water - dark blue shows areas of much below normal.
As noted in the time series (from top to bottom), during the past 4-weeks the area of much warmer than normal surface water (red in top panel) has remained very warm and has not expanded in area. This area of very warm surface water in the Eastern and Central Tropical Pacific is due to the strong upwelling of very warm subsurface water.
The much warmer than normal surface water will continue through the Northern Hemisphere winter and Southern Hemisphere summer.
This is the first El Niño to form near the South America Coast near Peru since prior to 1981. Thus, weather around the world will be much different than during the El Niño events from 1982 through 2020.
Expect ENSO El Niño conditions becoming stronger into the northern hemisphere winter - southern hemisphere summer.
An ocean temperature cycle typically persists for 2 or 3 months and then transitions to another cycle - such as transitioning from warming to cooling and then back to warming.
