    Winter Forecast Now Online

    in Spring Weather Discussion

    Posted · Edited by eyeofthestorm

    The Gulf Stream hasn't moved south, but it has been greatly weakened over the past several months according to NOAA and US Navy ocean models.

    http://polar.ncep.no...-rundate=latest

    Here are two comparisons from August and September last year which show several ocean currents including the Brazil Current, the Caribbean current, the NAD, the Canary current and the Norway current which now either cease to exist or have been greatly weakened

    I by no means believe BP could cause this, people tend to put the blame on somebody because it is convenient. Besides the Loop current is one current which still appears to be working when it is clear the damage appears to be done elsewhere some several thousand miles from the Gulf of Mexico. I am actually quite mystified that nobody is factoring this into their winter forecasts since the gulf stream/NAD is the UK's central heating system. I also believe the SST data from the models is wrong, there is no way they could remain at the norm with this apparent disruption to the ocean circulation, and NASA satellite data confirms this below which is very similar to the Data on Netweather Extra.

    As usual with anything weather related the media and the Met Office wont say anything until the effects are imminently felt.

    I dont see how people can deny these facts, but it does make things difficult when we have people all over the internet bent on blaming BP for something of this scale which makes no sense whatsoever.

    Gulf Stream still very weak. Not only that but many other ocean currents have either vanished or are greatly weakened. I am sure there are short term variations in the speed of the stream but surely nothing of this magnitude.

    We need a new thread on this which focuses on just facts without linking to people like the Earl of Sterling!!

    Well there's data from loads of buoys around the British Isles here - although being an NOAA site the temps are all in old money!

    http://www.ndbc.noaa...d_Kingdom.shtml

    No sign of any cooling that I can see!

    Actually, even if the Gulf Stream/NADC switched off completely for 100 years, why would the SSTs in the English Channel be 7c below normal? :(

    Thanks for the link, bookmarked it. This kind of proves my point though. The ones in yellow are Met Office owned and the ones in red are privately owned by industry. The private data isn't available for free I dont think, but all the above appear to be fed into Netweather Extra which I pay monthly for. The Private data was showing the colder temperatures whilst the Met office owned ones were not. Which kind of leads me to think is the Met Office playing with its data? The only way to settle this is to go swimming in the sea because its all too confusing with different sources showing different data. :)

    its totally wrong see Essan post above or even the wetterzale sea temps on here..sea temps are mostly above or around average across the North Atlantic and around the British Isles :winky:

    Well if it is correct we are in trouble this winter. Probably is wrong and there is some error in the data. But I am surprised no one has fixed it yet.

    I can't believe those figures, Brighton, Yarmouth and Skegness appear to be the only ones about right - there shouldn't be anywhere around our coasts lower than 14C at this time of year and the south coast should be about 16 to 17C. Even if the buoy were in line with an outflow from a river, there should not be any rivers with a temp below 10C at the moment.

    I know what your saying, but I cant help think though it is indeed correct. There are large parts of the North Atlantic well below normal too as shown by the NOAA satellites, and it is just too much of a coincidence to me that with the gulf stream losing over 90% of its strength. It has shown the same thing for weeks, and by now you would of thought it would of been corrected.

    How can the sea temp at Brighton be 6.7c higher than at Bournemouth?!

    I dont know, but that is according to NetWeather Extra. Some of these Buoys are maintained by private industry and I am not going to put the blame on the Met Office for playing with figures. However one can see from the ocean forecast models that the gulf stream has almost vanished in the past 12 months, so maybe this information is been sat upon.

    Surely the biggest concern for this and future winters is the gulf stream situation?

    Here is the latest SST Buoy data from Netweather Extra, as I said on an earlier page it appears some of this data is maintained by private indistry and some by the Met Office. Also NOAA polar orbiting satellites and not the model data confirm the well below average North Atlantic SST.

    Looks like it is weakening further.

    http://i82.photobuck...urr20090820.png A reminder of how things looked last year

    As someone else pointed out, the 200m charts are irrelevant. It is the surface velocitys which carries the warm waters towards the UK. It is not until it heads back down from the arctic regions does it begin to sink

    Type latest in the box for the current run

    People who blame BP seem to add the loop current is broken, but if I am reading it right the loop current seems to be functioning fine. It is further up the stream the chaos begins, and of course further down the stream too. It would be good idea to keep a daily eye on the ocean models to see how things play out.

    Ok guys i know that the gulf stream may or may not be running but in the winter if the gulf stream runs slowly will we have cold winters like moscow or places like that because we are the same lattidute as them? :)

    In theory yes, the North Atlantic current is what keeps the UK in a temperate climate and gives us milder winters than most places on out latitude. Currently the Gulf Stream seems to of almost fragmented, and the surface velocity's are well down, even down by the gulf they are well down on what they should be. I am no expert and we will have to see how things play out over the coming months. :drinks:

    Somehow I just cant see how BP fits into all of this. The Internet abuzz with people putting blame on BP. To me it is technically impossible for BP to somehow stop almost the entire gulf stream, and severely disrupting the rest of the currents.

    I think this needs a separate thread which just focuses on hard data, not some blog which claims it is going to wipe us all out!! Been a fascinating debate tonight anyway.

    From Wikipedia http://en.wikipedia.org/wiki/Gulf_Stream

    "Typically, the Gulf Stream is 100 kilometres (62 mi) wide and 800 metres (2,600 ft) to 1,200 metres (3,900 ft) deep. The current velocity is fastest near the surface, with the maximum speed typically about 2.5 metres per second (5.6 mph).[20] As it travels north, the warm water transported by the Gulf Stream undergoes evaporative cooling. The cooling is wind driven: wind moving over the water cools it and also causes evaporation, leaving a saltier brine. In this process, the water increases in salinity and density, and decreases in temperature. Once sea ice forms, salts are left out of the ice, a process known as brine exclusion.[21] These two processes produce water that is denser and colder (or, more precisely, water that is still liquid at a lower temperature). In the North Atlantic Ocean, the water becomes so dense that it begins to sink down through less salty and less dense water. (The convective action is not unlike that of a lava lamp.) This downdraft of heavy, cold and dense water becomes a part of the North Atlantic Deep Water, a southgoing stream.[22] Very little seaweed lies within the current, although seaweed lies in clusters to its east"

    Unless I am reading it wrong the link below seems to establish the North Atlantic current has indeed stopped. There is virtually nothing impacting the UK and Norway.

    http://polar.ncep.noaa.gov/ofs/viewer.shtml?-natl-cur-0-large-rundate=latest

    Now compare this to august 20th last year and you will see the huge contrast.

    Adding to that, the SST temperatures I posted yesterday from NetWeather extra after doing some searching on the net, some are I think maintained by private industry and some by the met office. Now either the Private sector has it wrong, Or the Met Office is manipulating data... Surely Not!!! :lol:

    Is this down to the BP Oil spill? Probably not, the Gulf Stream has been weakening for years, and now appears to of taken a major step further

    Has anyone noticed the cold SST around much of the UK? Many places in single figures according to Netweather extra. According to the actual observed temperatures as opposed to the model projections they are some 7c lower than the model is predicting. Anyone seeing the same thing?

    Could do with some more snow here in Hexham was very disappointed on Monday night, the snow was a wintry mix initially before turning to rain.

    Hardly anything left here just a few cm and nothing in the town :wub:

    BBC mentioned some persistent snow showers over Northumberland Tomorrow.

    But Sunday probably my best hope for seeing anymore snow :lol:

    Lets hope the full effects of the Stratospheric Warming are felt soon, some incredible potential in FI on the ECM 12z tonight
