Yes they do sometimes. We'll see how warm or not the Pacific waters get in those regions soon enough.

Are there we have it. Official now. Painted in blue La Nina. July-August-Sept to current. Weak La Nina close to have become a moderate one.








Check out the actual dive. WOW. Intense Nino down to Nina within like 7 months

Has this La Niña affected global weather and climate over the past few months? It’s very tough to point to any one weather or climate event and say “that was due to La Niña!” (In our business, the process of identifying the causes of certain events is called attribution.) There are a lot of different, complex things going on in the atmosphere at any one time, interacting and affecting each other. It’s like trying to identify exactly which sneeze is due to the head cold you have, or to a random bit of dust floating through the air.


The average for the October – December period was -0.8°C, so we now have four successive three-month periods with an average cooler than the La Niña threshold of -0.5°C. Five successive seasons are required to officially qualify as a La Niña event. Forecasters are confident that the November – January period will qualify as continuing the La Niña, but predict that the next period, December – February, will be warmer, and likely end up in neutral territory (between -0.5°C and +0.5°C).

And there it goes.


Goodbye La Nina. It's now Officially the end of it.


Now we are in Neutral and wait to see if El Nino Develops this summer.

ENSO Alert System Status: Final La Niña Advisory


EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION
issued by CLIMATE PREDICTION CENTER/NCEP/NWS and the International Research Institute for Climate and Society 9 February 2017


Synopsis: ENSO-neutral conditions have returned and are favored to continue through at least the Northern Hemisphere spring 2017. La Niña conditions are no longer present, with slightly below-average sea surface temperatures (SSTs) observed across the central equatorial Pacific and above-average SSTs increasing in the eastern Pacific (Fig. 1). The latest weekly Niño index values were -0.3°C in the westernmost Niño-4 and Niño3.4 regions, and +1.5°C in the easternmost Niño-1+2 region (Fig. 2). The upper-ocean heat content anomaly increased during January and was slightly positive when averaged across the eastern Pacific (Fig. 3), a reflection of above-average temperatures at depth (Fig. 4). Atmospheric convection remained suppressed over the central tropical Pacific and enhanced over Indonesia (Fig. 5). The low-level easterly winds were slightly enhanced over the western tropical Pacific, and upper-level westerly winds were near average. Overall, the ocean and atmosphere system is consistent with ENSO-neutral conditions.

The temp anomalies for all regions. Nino 4 & 3.4 region still a touch colder than normal but near neutral. Nino 1+2 region is well above norm. Nino 3 is now above norm.




The forecast for Region 3.4
