El Niño Arrives; Expected to Persist through Winter 2009-10
NOAA scientists today announced the arrival of El Niño, a climate phenomenon with a significant influence on global weather, ocean conditions and marine fisheries. El Niño, the periodic warming of central and eastern tropical Pacific waters, occurs on average every two to five years and typically lasts about 12 months.
NOAA expects this El Niño to continue developing during the next several months, with further strengthening possible. The event is expected to last through winter 2009-10.
“Advanced climate science allows us to alert industries, governments and emergency managers about the weather conditions El Niño may bring so these can be factored into decision-making and ultimately protect life, property and the economy,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator.
El Niño’s impacts depend on a variety of factors, such as intensity and extent of ocean warming, and the time of year. Contrary to popular belief, not all effects are negative. On the positive side, El Niño can help to suppress Atlantic hurricane activity. In the United States, it typically brings beneficial winter precipitation to the arid Southwest, less wintry weather across the North, and a reduced risk of Florida wildfires.
El Niño’s negative impacts have included damaging winter storms in California and increased storminess across the southern United States. Some past El Niño’s have also produced severe flooding and mudslides in Central and South America, and drought in Indonesia.
An El Niño event may significantly diminish ocean productivity off the west coast by limiting weather patterns that cause upwelling, or nutrient circulation in the ocean. These nutrients are the foundation of a vibrant marine food web and could negatively impact food sources for several types of birds, fish and marine mammals.
In its monthly El Niño diagnostics discussion today, scientists with the NOAA National Weather Service Climate Prediction Center noted weekly eastern equatorial Pacific sea surface temperatures were at least 1.0 degree C above average at the end of June. The most recent El Niño occurred in 2006.
El Niño includes weaker trade winds, increased rainfall over the central tropical Pacific, and decreased rainfall in Indonesia. These vast rainfall patterns in the tropics are responsible for many of El Niño’s global effects on weather patterns.
NOAA will continue to monitor the rapidly evolving situation in the tropical Pacific, and will provide more detailed information on possible Atlantic hurricane impacts in its updated Seasonal Hurricane Outlook scheduled for release on August 6, 2009.

Oh praise Gaia and the Profit! at long last!
Sarc. off-this will be a weak one-there are some who
say it may not make it though the Boreal winter…
Horrors! We must raise taxes, immediately!
WIll it be hot or will it not.
Place bets now!
This will mean more BBC and Monbiot driven thermageddon. I can hardly wait…
I think AGW needs another 1998 to stay in the game.
” NOAA understands and predicts changes in the Earth’s environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.”
What an arrogant, ignorant piece of bloviation that is! It enrages me every time I read it (but then I am also enraged by John Lennon’s moronic mewl ‘Imagine’). On the other hand, what would one expect from an outfit that styles itself the Administrator of Ocean and Air? Poseidon and Aeolus wrapped up in one.
At the name of NOAA, every knee shall bow.
Something to mindful about –
Per Hansen et al, ***2008 Global Surface Temperature in GISS Analysis”*** last January,
“Given our expectation of the next El Nino beginning in 2009 or 2010, it still seems likely that a new global temperature record will be set within the next 1-2 years, despite the moderate negative effect of the reduced solar irradiance.”
Keep watching, and remember.
The last paragraph kind of says it all…
“…NOAA understands and predicts changes in the Earth’s environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.”
“NOAA understands and predicts changes in the Earth’s environment, from the depths of the ocean to the surface of the sun”
Well that is some self-praise.
At least they don’t claim they do accurate predictions.
Joe Bastardi from Accuweather, who predicted the El Nino back in January, predicts that it will be no more than a moderate one, and that it will fall apart by late fall or winter. That being said, the AGW’ers and the media will no doubt start having a field day as it will be proclaimed that “global warming has resumed just like the models predicted.” I can’t wait (heavy sarcasm).
hmmmm
The announcement above says –
“NOAA scientists today announced the arrival of El Niño”
but
following the links to the EL NIÑO/SOUTHERN OSCILLATION (ENSO)
DIAGNOSTIC DISCUSSION, they say –
“During June 2009, conditions across the equatorial Pacific Ocean transitioned from ENSO-neutral to El Niño conditions.”
and –
“Current conditions and recent trends favor the continued development of a weak-to-moderate strength El Niño into the Northern Hemisphere Fall 2009, with further strengthening possible thereafter.”
So apparently we have El Nino “conditions”, with forecast to develop into an El Nino in the near future.
I couldn’t find the formal definition of ‘x temp for y months’ on the NOAA web site. Am looking forward to that discussion from Bob T or others here.
Yes Brian, predictions that are actually observed should be emphasized.
found it ….
NOAA’s Climate Prediction Center, which is part of the National Weather Service, declares the onset of an El Niño episode when the 3-month average sea-surface temperature departure exceeds 0.5oC in the east-central equatorial Pacific [between 5oN-5oS and 170oW-120oW].
… so in a couple more months, we may have a definitive 3-month average.
UK Sceptic, I fully agree (as a fellow UK BBC sufferer), but won’t it be great if the high temperatures don’t materialize? How will they defend that? El Nino, but cool temps. I can’t wait.
Does anyone ever read Ed Berry’s blog? http://weatherclimatelink.blogspot.com/
Ed is not so sure that this El Nino will have staying power. Here is what he wrote recently (some of this is over my head).
“Like the recent behavior of the financial markets, we have seen an “AAM correction”. However, is this simply a subseasonal variation destructively interfering with El-Nino, or is a process beginning that not only could weaken EL-Nino this upcoming boreal autumn, but perhaps bring a La-Nina situation boreal winter 2009-10? The answer is unclear”
And most recently: “The bottom line is that the global wind and convective signals continue to lead the SSTs (broken record), and the ENSO situation is unclear (will stochastic forcing have giveth then taketh away?).”
UK Met Office and CRU web site has been down for three days now! Bet they can’t wait to get back online with their dire predictions.

Well, they’ve been predicting it long enough. Remember that while we may be in the negative phase of the PDO, it doesn’t preclude experiencing a few El Niño events. It’ll probably turn out to be a weak event, despite some folks’ hopes for a repeat of ’98. La Niña events, on the other hand, tend to be predominant during the DPO’s negative phase. The good news, I suppose, would be fewer Atlantic hurricanes – haven’t had a named storm yet this season – not even a “Tiny Tim”.
“Flanagan (08:24:55) :
Yes Brian, predictions that are actually observed should be emphasized.”
And when those “predictions” are wrong (Like arctic free of sea ice within 5 years) should also be emphasized (Rather than ignored)?

Next time they are proven wrong, we’ll know their climate science was not advanced enough… Just as for the Communist planification, they’ll have to find another qualificative to describe their product: Hyper-cerebral, Mighty-weaponed, Multi spatial climate science… LOL
Love Ed Berry and Joe Bastardi I feel that the Winter of ’09/10 will be a memorable one
but not for the Warmists among us.There is a lot of cold out there. It would have to be a Nino’98 to even budge it…
The next few months are going to be very interesting for anyone who follows the evolution of global temperatures and the whole climate change debate.
Remember, the UK MetOffice predicted about seven months ago that 2009 is going to be one of the top five warmest years ever recorded. The great La Nina of 2007/08 and the minor one peaked in January 2009 has gone. Then we have this announcement from NOAA about the beginning of a new El Nino. The global temperature anomaly tends to lag short-term ENSO variations by 2-5 months. It seems that the 2009 forecast is going to ‘overshoot’ the real 2009 value, like any other years since 1999. Altough this is not good for the credibility of the MetOffice, the real question is the temperature response to the next El Nino. If the global anomaly can’t exceed the pre-2008 levels during an El Nino, the main assumption of the AGW camp that increasing CO2 is the main driver of global temperatures will get a serious hit.
According to Dr. Spencer at UAH, the satellite-measured global near-surface temperture anomaly in June was zero (0.001°c) with respect to the 1979-98 reference period. The lack of statisticially significant warming since about 1995, the lack of any warming trend since 1997, and the obvious cooling trend since about 2001 can be seen even in the HadCRUT dataset. Despite of this fact and the systematic bias in the annual global temperature predictions of the MetOffice, Phil Jones just keeps repeating the very same mantra:
“The fact that 2009, like 2008, will not break records does not mean that global warming has gone away. What matters is the underlying rate of warming – the period 2001-2007, with an average of 14.44 °C, was 0.21 °C warmer than corresponding values for the period 1991-2000.”
The recent 9-year cooling trend may have not been caused by a single ENSO event, it must be something else – something they weren’t aware of. The effects of the oncoming El Nino, the recovery or non-recovery of global temperatures to pre-2008 levels will be a very important issue.
This single event can prove the whole CRU and MetOffice wrong (or ressurect their credibility if the outcome will be the opposite).
Suddenly, weather will magically become climate again. Because when it’s hot, it’s climate. When it’s cool, it’s weather.
Follow the weekly updates (out every Monday). The Oceanic Nino Index needs to be +.5 or above (the one posted for July 6th was at .2) and then forecasted to continue at that or above level for 3 months. Not all forecasting models predict this. The statistical models indicate a near equal chance of neutral or El Nino. The dynamical models indicate mostly an El Nino condition. Most predict a weak one at that. It is to be remembered that during a cool PDO flip, El Nino’s will occur. Just not very many and not very strong. The last 3 have all trended down. I still consider the PDO to be in a cool phase and I think that the trend will continue for weaker and weaker El Nino’s. This is probably why NOAA issued an El Nino ADVISORY. If this turns out to be a weaker El Nino, the Northwest could still see very wintery and snowy conditions.
Following on what Chuck L wrote, Ed Berry (link below) is cautious about an El Nino “false alarm” and considers the ENSO situation “uncertain.”

Plus, we have to have five months of consecutive overlapping 3-month seasons with an ONI of +5 or more before officially declaring an “El Nino,” as opposed to “El Nino conditions.” I looked for the latter in the above press release, and didn’t really see a waffle here. The closest is “NOAA expects this El Niño to continue developing during the next several months…” But that treats the El Nino as already “here.”
Here’s the official distinction:
—————————
NOAA Operational Definitions for El Niño and La Niña
El Niño:characterized by a positive ONI greater than or equal to +0.5°C.
La Niña:characterized by a negative ONI less than or equal to -0.5°C.
By historical standards, to be classified as a full-fledged El Niño or La Niña episode,these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.
CPC considers El Niño or La Niña conditions to occur when the monthly Niño3.4 SST departures meet or exceed +/-0.5°C along with consistent atmospheric features. These anomalies must also be forecasted to persist for 3 consecutive months.
———————————-
We do not even have the first month of data in, yet, to qualify for the run of five months needed here. The latest three months of averaged data, April to June, is +0.2.
But let’s give NOAA some rope here, and see if they do better with this “forecast” than they have with the last two or three official US winter forecasts.
