  1. Thank you John for your explanation, though the maths are far beyond me.

    In the winter of 62/63 I was a humble scientific assistant at Heathrow when we had the situation on a number of times when the warmer Atlantic airs made an approach but beyond getting as far as the far SW peninsula of the UK they were really unable to penetrate to any great extent. I think we had one occasion where a warm front approached from the SW to be preceeded by snow and the precipitation to remain as snow behind it. This appears to have been a rare occurance and brought some gasps of amazement.

    If my memory serves correct the final break through came from the north west. For most of the time North West Scotland (Stornaway logged up quite a few +4C's) was pretty mild in comparison to SE England and it seemed to me at the time that the attack was coming from the weakest point and a bit like using low gear to drive a car up a hill, whereas in high gear the engine would stall.

    I also get the impression that it must take a terrific amount of energy to dislodge a well established "cold pool" and it really does become a battle of the air masses, the energy of the warm fighting against the inertia of the cold.

    It is interesting to note that over the past few days the timing of the warmer incursion has steadily been moved from just before Christmas until after.

    So despite what Joe B is saying I am watching this space with interest, though I am not putting any money on it either way.

    Interesting. Makes sense to me. I notice that the models often underestimate the stubbornness of cold. This last week has been a great example. 3 day forecasts constantly predicting breakdowns of cold - as they are now - that never materializes. watch this space!
