El Nino Has Finally Arrived, Far Weaker Than Predicted
An anonymous reader writes "The periodic warm weather pattern called El Niño has finally arrived in the mid-equatorial Pacific Ocean, more than a year late and far weaker than predicted by scientists. "The announcement comes a year after forecasters first predicted that a major El Niño could be in the works. At the time, NOAA predicted a 50% chance that an El Niño could develop in the latter half of 2014. The agency also said the wind patterns that were driving water east across the Pacific were similar to those that occurred in the months leading up to the epic El Niño of 1997, which caught scientists by surprise and contributed to flooding, droughts and fires across multiple continents.
In the end, last year's forecasts came up short, in part because the winds that were driving the system petered out. Researchers, who have been working to improve their forecasting models since 1997, are trying to figure out precisely what happened last year and why their models failed to capture it."

But computer models are always right and we can NOT investigate further....science is settled.
It has been one of the coldest and wetist winters in awhile. High around 39 should not be a common occurrence on the gulf coast but it feels more like Seattle than a subtropical place. It got in the 70s only a few times last February.
El Nino was supposed to be big as a big surge of very warm water up to 150 ft deep and almost 1,000 miles long headed east. However the winds picked up and chilly Antarctic current which cools west South America mixed in for a few months so it is not so warm anymore.
Weather is complex and last decade (no I do not deny global warming) had a solar null which means cooler temperatures and more la nina events like those in the mini ice age from 1400 - 1840 which explains colder temperatures and dryer conditions. California hit a 500 year drought where the climate actually changed from mediterranean to desert. Same in Chile and Peru.

Empirically, ENSO has been tightly associated with bursts of warming -- nearly discrete jumps in global average temperature. The 1997-1998 super-ENSO event was very directly associated with a jump of nearly 0.15 C, and temperatures have remained basically neutral ever since except for peaks in "normal" ENSO years that quickly regressed to a mean. Indeed, if you look at the SST record (arguably more pristine than the heavily processed global temperature record, at least in the recent past) it exhibits a pattern called Hurst-Kolmogorov (punctuated equilibrium) jumps with the transitions often associated with ENSO. This is actually one of the arguments of skeptics -- global temperature is almost certainly regulated by CO_2 concentration, but only weakly/logarithmically and according to radiative theory, the total climate sensitivity (increase per doubling of CO_2) should be between 1 and 1.5 C, which is warming but unlikely to be catastrophic in any reasonable future CO_2 scenario. The unknown factor is how much of the warming is due to shifts in a punctuated, locally stable equilibrium from what amount to natural factors, the biggest of which are the multidecadal oscillations and associated shifts in global atmospheric circulation patterns (where as noted, ENSO especially is an empirical smoking gun in the shifts) but which also include discrete shifts in the thermohaline circulation patterns, especially at certain critical junctions in the Atlantic, and the possibility of nonlinear effects from solar variability. Since the system is highly multivariate, chaotic, nonlinear, and with profound feedback loops and self-organized dissipative structures in abundance, it is incredibly difficult to model and the general circulation models yield almost no useful information beyond "if you increase CO_2, it will more likely warm than cool" which we already knew from radiative theory in the first place and which is built into them in such a way that they can give no other answer. There is little reason to believe that the multimodel ensemble mean of means of the many different models has any real predictive force, however, and in fact that mean is systematically diverging from the observational record just as it has systematic deviations in its hindcast from the historical record.
This is why catastrophic global warming enthusiasts are so excited about the prospects of a new super-ENSO. If it happens, it could cause another Hurst-Kolmogorov jump, bump the average temperature a bit, and validate the models (or at least, rescue them from a richly deserved back-to-the-drawing-board oblivion). It is difficult to escape the feeling that they want this to happen, that they want the world to heat up disastrously to punish the human race for using energy and building civilization. One would think that evidence that TCS was not, in fact, 2 to 3 C but instead was 1-2 C (or even less) would be welcome news, but for them it would be acknowledging that the deliberately created panic, the political manipulation and selling of the catastrophic warming meme, and the associated shifts of enormous amounts of money into ameliorating a hypothetical disaster on the basis of unproven models has been directly responsible for the perpetuation of 1/3 of the world's population in a state of energy poverty.
