El Nino watch has been issued by NOAA, with large-scale atmospheric and oceanic changes

The ENSO, often known as the "El Nio Southern Oscillation," has two phases: El Nino and La Nina. The equatorial Pacific Ocean in this area alternates between warm and cold phases on a regular basis.

WHERE THE OCEAN AND THE ATMOSPHERE CONVERGE

The most straightforward explanation is that it occurs as a result of a complicated interaction between pressure, winds, and ocean currents.

You'll also notice that the trade winds are now beginning to play a significant part in the quick change from cold to mild ENSO conditions.

ENSO Winter to Spring evolution

The latest global ocean analysis below shows two main regions we watch. First are the ENSO regions, with strong warming starting in the eastern regions.

THE EL NINO IS RISING

you can see the rapid warming trend in regions 1 and 2. Central region 3.4 also follows behind, with eastern region 3 already well in the warm anomalies.

WEATHER STARTS IN REGIONS 1 AND 2

The ensemble forecast for the 1+2 ENSO areas is shown below. Once more, temperatures are rising quickly, and an anomaly of 2 to 4 degrees above average is predicted.

Stronger wind shear is the cause, which keeps storms from forming and intensifying.

ENSO AND THE HURRICANE SEASON

There is often a strong and prolonged low-pressure region in the North Pacific during the El Nino winter season.
