THE BLOB Has Dissipated

Guest Post by Bob Tisdale


Animation 1 – Sea Surface Temperature Anomaly Maps from the CMC Environment Canada (September 17, 2016 and October 27, 2016)

The Blob was the name given to the area of elevated sea surface temperature anomalies in the eastern extratropical North Pacific. It formed in 2013, coupling with a ridge of high pressure that impacted weather patterns across North America into 2015.  The Blob was the primary contributor to the reported record high global sea surface temperature anomalies in 2014, and contributed to the record highs in 2015 along with the 2015 portion of the 2014/15/16 El Niño. (See General Discussions 2 and 3 of my free ebook On Global Warming and the Illusion of Control – Part 1.  Also see the series of posts about The Blob for additional general information.)

After a noticeable drop in the sea surface temperature anomalies for that region of the eastern extratropical North Pacific that lasted from late-2015 through mid-2016, the Blob reemerged in August, with the sea surface temperature anomalies peaking in September for 2016.  See Animation 2, which includes daily sea surface temperature anomaly maps running from June 1, 2016 through today. (Depending on your browser, you may need to click on the animation.)


Animation 2 – Daily Sea Surface Temperature Anomaly Maps from the CMC Environment Canada (June 1, 2016 through October 27, 2016)

As shown, The Blob began to decay noticeably in early-to-mid October and has, now, basically disappeared from its normal location, though there are still elevated sea surface temperature anomalies in the eastern and central extratropical North Pacific.

We should expect a noticeable decline in the sea surface temperature anomalies this month in The Blob region, and in the North Pacific as a whole, when the monthly sea surface temperature data for October are published early next month.

Will The Blob disappear for good in the future or will it reappear annually during the boreal summer months as part of a new seasonal cycle?  Only time will tell.

As someone who used to live in California, the offshore oceanic conditions do greatly influence weather in California. Whether the fronts go into Washington and BC, or dip down enough to hit California, seem determined by standing highs offshore.

Living in California I can note that the “Blob” did cause a bit of consternation that the spring rains did not materialize as strongly as “El Nino” usually delivers. Now that the “Blob” has moved on we have received some welcome showers recently. Enough so it seems that the news was reporting “unprecedented” (“they keep using that word. I don’t think it means what they think it means”) rain. Well at least unprecedented since the last time it happened.

I heard that the precipitation for our area (S.E. Washington State) thus far into the month of October places it among the top 10 wettest Octobers since 1885.

Wow, all of us have become accustomed to the The Blob. I’m really going to miss it. It’s become part of my family and now … My son was going to dress up as it for Halloween and now it would seem it would be a cruel gesture.
Maybe they can reduce the “normal” by 3 deg C and have it come back to life.

It looks like the path that hurricane Matthew took is also colder after the event. So it would seem that a followup hurricane in that region is less likely.

Today is the third day of rain with the forecast for the next 10 days also showing continuing rain here in No California. Currently there are two atmospheric rivers which could further impact the PNW, if they move into the region. The AR to the south is the closer stream, while the other stream is further out to the west but at the right latitude to eventually reach into Oregon/California.. ..,36.44,497

Actually, most of Eastern Washington was very wet last winter, one of the wettest ever recorded. Kennewick in 2015 was only about an inc below normal in precip, after being about 2 inches below normal in 2014 and 2015. 2016 should end up with an above average rainfall for Kennewick.

No it was not unusually wet in the Tri-City area where I live,the 2016 Summer was very DRY. This October is the first time in THREE years that a month of above average precipitation shows up.
In Kennewick,where I reside,the yearly rainfall average is around 7.25 inches in a year. It is NORMALLY a dry place.

Apparently the SOI hasn’t met the criteria for a La Niña. In fact, Weather Bell was saying Saturday that the SOI hasn’t reached the threshold and that changes going on around Australia and the Indian Ocean may cause the La Niña to dissipate. Joe Bastardi said, also, that we could possibly have another El Niño next year.

Depending on how the elections go on 8 NOV, environmental measurements such as SST may not really matter anymore as far as US of A policy go.
One way, CO2 caused environmental Armageddon is a foregone conclusion, carbon dioxide emission taxation will be imposed across the nation, among other not-so-nice outcomes. Measurements (adjusted or otherwise) become less science and more of a hammer to pound home the ideological advance toward a More Perfect Global Union.
The other way, while science should (one hopes) become more realistic/based upon empirical measurement and scientific methodology, utilized to assist in more realistic policy choices for daily use of our surroundings/resources (air, soil, water use) – and the CO2 scare becomes the shrill scream of the losing side (to be ignored, completely at least for four years) – an all-of-the-above approach to energy production would be a ‘breath of fresh air’.
Just sayin’.

“Just sayin'”
Your sayin is politically simplistic. Hillary, if elected, will almost certainly face a Republican congress and will have no more success advancing an agw agenda than her predecessor. Trump, in the extremely unlikely event of his election, does not have the political smarts or mandate to dismantle existing climate change policy.
Climate change is a fringe election issue at best. Neither candidate will risk political capital to attempt more than minor changes to policy.

Is that what has caused the record low in Arctic ice, for the end of October?

October 27, 2016 8:48 am

Thanks Bob,
The scale of the blob, watching it move easterly, and the speed with which it dissipated, about two weeks, suggests it is of very shallow depth, perhaps just a few MM of water depth involved in that SST. If it were deeper, it would take longer to dissipate, because water cools far more slowly than air.
It also suggests that it might be related to sea surface roughness and incoming solar, i.e. wind and clouds.
It all says “weather pattern” to me. Just look at the waves of the La Niña on the Equator, moving west, wind driven. They arrive and dissipate with similar speed.
Too bad we can’t get a retroactive view of winds there from the web page. Might be interesting to see what was going on.

“It also suggests that it might be related to sea surface roughness and incoming solar, i.e. wind and clouds.”
I followed the blob a bit at Nullschool. It dissipated when there was a strong low pressure area over there. Strong winds and mixing of the upper layers, evaporation, clouds and no incoming solar seemed to make the blob disappear. Unfortunately it was not visible what was happening below the surface: which subsurface water with what temperature was coming in?
I suppose high pressure area’s (a few wind, incoming solar) help to sustain blobs.
It would be interesting to know how deep the warm water layer was. I myself think it will at least have been a 5-10 meter, perhaps a 25 meter. Otherwise it would have disappeared after the first strong mixing winds. And it couldn’t have had such a high influence on the air temperatures last year as well.

Well……, but it moved the jet streams path over the continent, and that changed the weather.

My guess would be the high pressure system is the main cause of the Blob. Things get hot underneath high pressure systems. The longer they sit in one position, the hotter it gets underneath them.

Yup, it was pretty shallow. This article from Scott Sistek of KOMO in Seattle ( ) mentioned that the blog was only 25 meters deep, much more shallow than the blob of a couple of years ago, according to Washington State Climatologist Nick Bond. The article, posted on September 30th, said “Bond says the shallow nature of this Blob means if we get a really stormy autumn, it can help dissipate the blob over a month or so”
And that is what has happened.

Just a simple farmer here. so could someone please tell me exactly where the ridiculously resilient ridge was/is that contributed to this thing? Is it an upper level ridge or what? I can’t seem to find much info but then I’m not to internet savvy either. A neighbor asked me why the harvest weather up here in Saskatchewan has been so terrible (one system right after another, cold with 8 inches of snow on Oct. 5th we never recovered from). I’ll be the first to say it’s weather not climate, but beyond blaming the “blob”, what is the weather phenomenon that seems to be persistently driving the jet stream and storm tracks right across us in Sask? It’s looking like this will be the first time we will have ever had crop out over winter. Any more of this “warming” and we might have to seed it all back to grass and raise livestock.

Dear Farmer Olson,
Until a more well-informed commenter answers your excellent question, here is some information from Weather Bell for you to consider:

La Niña conditions in the tropical Pacific mean a drier water year for the U.S. West Coast due to a blocking high pressure ridge:

comment image
(Source: )
2. This info., while dated October 17, 2016, may ALSO describe what had ALREADY happened farther north, as you guys are about a 45 (?) days ahead of us in the onset of autumn/winter conditions up there:
A strong El Niño came to an end in June, putting forecasters on watch for a La Niña to develop over the fall and winter. La Niña strengthens the northern jet stream and causes the southern jet stream to weaken, guiding moisture in the northern tier of the country. …
The cooler-than-average waters will still influence the late fall and winter season. Even if the waters miss the needed criteria, borderline conditions can still affect weather patterns and resemble a weak La Niña.
With a fast northern jet stream, there will be occasional cold shots in the eastern U.S. {and, daresay, (smile), into Canada} …

(Source: )
3. Note the “blue blob” in Bob Tisdale’s (boy, was I afraid I would type “Blob Tisdale”!!) animation of SST data above. At the “Start” of the animation, it appears to zoom east, into the warmer (thus, lower pressure) warm “blob” area and you can see the warm blob shoved down and over toward the southwest. Then, around July, 2016, the blue blob looks like a big ocean liner docking at Long Beach, California. That cooler air, given the prevailing winds, may have had an impact on your late summer/early autumn in Canada (sure hope someone confirms or denies this guess!).
Okay. Hope at least part of that information is useful to you! (if even just as a starting point for your own research)
Your U.S. Ally for Truth,

Huh, according to WeatherBell, “La Niña conditions in the tropical Pacific mean a drier water year for the U.S. West Coast” And then it shows Oregon and Washington wetter than normal (correctly) And to think my whole life I thought Oregon and Washington were on the U.S West Coast. No wonder why JB thinks we will be warm and dry (typically the NW is wetter and cooler during a Nina, especially wetter during a weak nina)

Brian, good for you to stick up for Washington and Oregon. 🙂
I wonder if it has to do with the western coast of Washington (and of northern OR, too?) being in a unique climate zone called “Marine West Coast.” The “West Coast” may just be the westernmost edge of the “Continental” climate zone? Short-hand talk from a quick-minded, busy, man? (just fun to guess)

See that orange blob of warmth hovering over Oklahoma; I’ll take the 10-20 degrees above average anytime over the blizzards a few years ago when heavy horizontal snow blocked out house visibility 300 feet away. Of course, this winter has yet to arrive, so who knows?

Below is a link to the site. Once there go up to the top and click the “Premium” tab and the video for that day and the last Saturday summary will pop up. Don’t worry, it’s free content. Won’t cost you a dime but I have found in an invaluable source for learning about weather.

So glad someone better informed bothered to help O. (I’ll bet it’s “Ole” — and he would, if I’m right, respond, “Ya, shure, you betcha” (just from my encounters with local Swedish heritage people). 🙂
Q for you (for Ole): Is there a way on Weather Bell for Ole to look at historical data analysis to see what they were saying (around June, 2016) what was expected to happen, given how things were shaping up in the Pacific, in Sept. – Oct. up north? That would give Ole the answer he is seeking, I think. He was more asking, “Why the blazes did we have such terrible weather this fall?”
Good to know how to look ahead, too.

The remnant of a typhoon tracked eastward across the pacific and approached Seattle with (rumored high) winds and rain, diverting just to the north just before landfall. I think intense storms over the ocean peel the heat away from the sea surface, like what was also observed for Matthew and the western pacific typhoons recently. Anomalies there have cooled Noticeably out west…

October 27, 2016 9:49 am

Judging by the animation it looks like it’s been moved into the Bering St.

This perfectly shows the source of the Blob, it’s a void between wind currents, so the airflow stalls, and the ocean water warms in the Sun. Which becomes a high pressure zone and the air goes around it.
Think of it as a thumbprint that sticks around for a while.

I think the 97 step in temp is the same sort of thumb print, the temperature changed in the 20 to 30 North Latitude band, the other non-tropical zones continued to do the same thing after as they did before.
The response is in degrees F for 1 W/m^2, the Whr (/m^2) listed is the same value, just expressed differently, to a watt of Sun light. Since I don’t adjust for clouds or anything else, this is the effective sensitivity.

Interesting ramifications for this winter if The Blob is gone and the LaNina weakens. These were the two major factors that In the past gave us higher pressures over Greenland and lower pressures under Alaska. Those pressure patterns gave us a negative arctic oscillication index that made the polar vortex visit US east of Mississippi River that resulted in cold winters. Will the AO index still go negitive under LaNada condition? Early winter? Late Spring? More snow?

October 27, 2016 10:40 am

The Blob should have been tested for a possible geochemical signature to eliminate the possibility that it was the result of volcanic activity on the sea bed.
