Maybe I'm just a natural pessimist but for any of the charts I look at for
the next week or so the most consistent feature seems to be the Azores High. This seems quite large, quite strong at 1032mb and ridging into the Bay of Biscay. Surely a decent cold spell is unlikely while this feature persists, as it usually does. While folks are looking to the North and East are they possibly overlooking "the bleeding obvious" ! Hope I'm wrong. Dave. |

No doubt the reason for lack of cold winters for us these days is the ever
strong high pressure(S, SW), and\or lack of low pressure to the South. Of course the two go hand in hand. The point is, the warmer waters to our SW obviously encourage\ invigorate the Azores High. I really think its as simple as this. I bet ya, as a layman, I'm right ;=). Of course, there are other areas of water which also come into play, but this is the main player, along with the poles (ice etc.). This is why any inland areas in Europe (Continent= Greece etc.) still have the potential of cold weather, and still do\will, but we won't. ;=( . Yes, we all know this, but do we? If we do, why do we still think the UK can have cold, snowy spells like the past?? It is all so glaringly obvious. SST's rule all, and they ain't gonna get cooler ;=( . ------------------------------------------------------------- "Dave.C" wrote in message k...

Hi Danny, Keep your eye on this link, as I am sure you do - https://www.fnmoc.navy.mil/products/...sstanomaly.gif The area to SW of UK and Bay of Biscay has been below average for some time now, however, it is coming towards normal now. Certainly not warmer as you seem to make out. As an aside, the area all around New Zealand looks a lot cooler than average, any ideas from those who follow these every day, Martin R ? Also a large negative anomoly around Dubai. TIA, Joe |

It is all so glaringly obvious. SST's rule all, and they ain't gonna get
cooler ;=( . There's a bit more to it than that. It's SST anomalies that are important, not simply the actual temperature. Although SST anomalies tend to be quite persistent they don't live for ever, changes being brought about by atmospheric warming or cooling and by dynamic effects in the ocean. And you have to ask what brings about SST anomalies in the first place. The atmosphere, largely. It's chicken-and-egg. Tudor Hughes, Warlingham, Surrey. |

Well I still managed to get a covering of snow on Nov 18th, a time of the year when SST's are still relatively high. Now if it can snow in mid November then it most certainly can still snow in January/February, even December! I don't think there has ever been a time when November has been particularly snowy in this country so if even today November can produce snow then there is hope for the 'proper' winter months.

Also a large negative anomoly around Dubai. .... no expert on these areas please note: the only thing about NZ I can come up with atm is that one of my relations lives there and this is what he sent me a few days ago:- " Our Spring has been a bit of a mixed bag, and in fact we are going through a bit of a cold spell at the moment. There is a lot of new snow on the mountains. We do get this sort of thing mast years, and there is little doubt that Winter is having its last fling. I crewed for a friend on Lake Te Anau for a four day cruise. We had a great time, and a lot of good sailing, but on the last day the snow came right down to the lake level, which is not common. " This might suggest that there is a lot of snow-melt coming off the land and/or recent storminess has stirred up the water from lower down & advected colder waters from higher latitudes as the depressions pass away. It does seem a rather large area for snowmelt to affect, so I would go with an enhanced storminess period. As to "Dubai" (actually more like Qatar/Bahrain etc.), that cold patch wasn't there a few weeks ago - the waters IIRC are relatively shallow in the Gulf and recent storms may have again turned up colder water - there have been reports of flooding etc., on the Iranian side of the Gulf. If this theory is correct, it should sort itself out provided the situation remains quiet. Best I can do. Martin. |

All I can do in return is clarify the SST off SW Sri Lanka, I'm off there on Thursday. ATB, Joe |

Danny.
I thought it was colder water that highs formed over, not warmer. Could you explain the reasons. Regards. Len. "danny(west kent)" wrote in message ...

Good to have you back Danny,it must be nearly a year since your last
offering concerning warm waters and cold weather was issued. Your new theory about the Azores High and warm water over the south west must be a meteorological first,and worthy of further studies among the educated elite of this group. I look forward to their findings.... RonB "danny(west kent)" wrote in message ...
