These coastal lows are most common in North America from late fall thru early spring. They are often not present at all during the summer when the primary jet stream is far to the north. It is fairly unusual for an active Low off the east coast of the USA to reach the UK as a significant feature. *Some ex-hurricanes may do it but they are re-invigorated over the Atlantic by the inclusion of cold air from the north. *Our most active Lows usually form to the southeast of Newfoundland or in mid-Atlantic. *We can get Lows from anywhere and at any time of year, even occasionally the northeast. *They are flabby but can be very wet. Incidentally, low pressure is the one meteorological element in which the UK trumps the US (except perhaps Florida with its hurricanes) and every other country except Iceland. The UK record is 925 mb and my personal best is 951 mb, and that in relatively tranquil south east England. We have more tornadoes per square mile than any other country. There are a number of other unique features to UK meteorology too. Not least the temperate climate. Though I dare say Oregon could argue that. The path for Lows generally is a spiral (in the right lunar phases perfectly so) that brings Lows in from Mexico and California diagonally across the USA and shunts them off into the Atlantic via Labrador and Newfoundland. Although this was a trend for much of this winter from the end of November until that last spell, I confess I have forgotten the effect that super typhoons have on the system. When an high is involved it is a little more complicated and Lows tend to come in from the North East Pacific, Seattle -Oregon and British Columbia, though I have not followed the path in Canada when that happens. They do seem to migrate south but overall it is a pall that covers the continent I think. This recent disaster mirrored in South America was an odd situation where a series of Highs did much the same thing as expected of Lows. Again it was in the absence of severe tropical storms that allowed the energy free reign. Not sure how of course. If I were to dare a theory it would be something along the lines that whilst the O/A pattern is a spiral that girds the earth almost twice in a cycle from the tropic to the Arctic Circle, the actual weather induced is following lines of least resistance. (Lack of suitable data from Russia and China precludes any follow-up from me.) Most interesting is that the pattern is seen reproduced in the obverse on the surface of the sun. Perhaps in that case we are observing only the upper atmosphere and must suspect the activity to be anticyclonic. But I feel it is more likely the result induced by the cause being focussed on another plane. If our weather is induced by luni-solar behaviour, it stands to reason the same effect is visible on the sun, induced by the planets. And since they all rotate in the same direction as one another.... I dunno.- Hide quoted text - - Show quoted text - I googled a bit and saw a diagram/map showing what you wrote about lows tracking across the North American continent from the Pacific. Though there is a meterological explanation for all that happens in weather, I still find this to be amazing. Bob |

Though you may have more tornadoes per square mile than any other country, they are puny in comparison to those in the central and southern USA (this is good thing of course, unless you enjoy death, chaos and mayhem).

They took the roof off a chapel just up the road from where I used to live and deposited it on the car of the landlord of a pub across the road a few minutes after he parked it after a lockin about 2 or 3 am one night. The town is nestled under an hill about 2 miles from the sea. Not much room to build up an head of steam. Quite enough to bowl a baby across a football field though. How much do you think we need? http://meteonet.nl/aktueel/brackall.htm is showing a potential difference of 90 millibars actually more like a hundred on the board at the moment. Quite a dart board. I'd say that's a positive anomaly, wouldn't you? Yet the Met Office have it tracking into the Arctic. If it does, there must be a good reason for that off the map. Quake or supercyclone or something. Personally I think it will cross N Scotland or broach at Norway. Vee schall zee ya? Meanwhile the smaller cyclone over the Hebrides is responsible (or coincident as usual, so to speak) for nice weather further down the country. Been nice here. Now let me ask those experts that are too stupid to have me blocked, why, with a low and a high approaching each other with a difference of 950mb to 1042mb, why don't they run toward each other? What on earth is that magic antielectropotential or whatever like/ unlike thing that is keeping them apart? Coriolis effect? Feckwits! |

What on earth is that magic antielectropotential or whatever like/ unlike thing that is keeping them apart? Coriolis effect? .....But unbowed In fact I may have something to redeem myself that might prove useful - if somewhat subject to permutation, nothing that needs a supercomputer though. The course being steered is some 15 degrees from that region of the Hebrides that, should it receive a low (gale warning in sea areas SE Iceland/Rockall) provides some nice weather for non haggis eaters. (Gentlemen in frocks seem to enjoy different tastes in weather to the rest of us.) But the point is that should deep lows track around that region by some 15 degrees the same seems to be true, Britain (or the bits with people in) tends to get nice weather on such occasions. I suppose I am being a little previous as the situation may require super-cyclones to initiate. Worth watching though. |
