Issued 0523, 7th December 2007 A change is on the way, with pressure rising markedly over the UK and, more notably, over Scandinavia. Tuesday is the transition day, as pressure builds strongly across the UK. Actually, the transition starts tomorrow if not today as the spell for the next phase is introduced. There's likely to be some rain for northern and western areas and that applies for the rest of the week too, as frontal systems attempt to move in from the west. There's considerable disagreement about the positioning and intensity of the high to the east or NE, with SE'lies or easterlies more likely than NE'lies. Despite the possible southerly component, it won't be as warm as it has been recently for the bulk of the UK, with the possible exception of the NW of Scotland. Anticyclonic to the west, probably the wrong side of the Mid Atlantic Ridge, leaving conditions in Europe to dominate: 9th December 17:40.http://sunearth.gsfc.nasa.gov/eclips...se2001gmt.html Dominate discussions and the hopeful fretting, that is. It is a confused spell -or one that condemns me to perdition, for now. BTW, there is a quake due when this catalysis ends. I don't know why I put off looking at the North American surface pressure maps for so long. I did make an attempt to understand the el Nino phenomenon once on a private weather forum. But that was before I realised the way they decide a call is based on statistics and involved a temperature gradient in the sea (FFS!) And that temperature difference was a matter of some half a degree centigrade. According to a three day glimpse of this: http://weather.unisys.com/ The standard model for a phase whose time is about 5 o'clock is a stream of Low pressure crossing the States from the Pacific at Baja to the Atlantic at Labrador. The corridor for this low is a stream running NE from LA to the shores of Hudson Bay and Tucson to Philadelphia. (Shouldn't that be Philodelphia?) There are two regions of High pressure bracketing this stream. One from the NE seaboard of the USA through the middle of Texas. And one from the Hudson Bay to Southern California. As a guess I'd say that the alternative (when the time of the lunar phase is about 7 o'clock) is a Low pressure system over Florida and Georgia in an arc down the banks of the Ohio and the seismic events are similarly settled at some 5.5 Mag max. I suppose it would be too obvious to suppose that arc continues on from Cincinnati to Baltimore. Makes a nice elliptical pattern though. I have no idea where the rest of the air systems would lie. |

Just as when the time of the phase tends to produce severe storms (as opposed to the usual suspects) when that time of phase is near 7 o'clock. Correction: Just as when the time of the phase tends to produce severe storms (as opposed to the usual suspects) in the northern North Atlantic, when the time of phase is near 7 o'clock. Since the latitude of the storm is most likely dependent on the declination of the moon and sun rather than the time of the phases, that one hour difference is interesting. That is, in the North Atlantic: Tropical storms are produced with a lunar phase at or near 6 o'clock. And with a lunar phase at or near 7 o'clock, tend to flow from Canada to Scotland/Norway. Or do they? |

A very strong counter current runs just north of the equator and probably explains why tropical storms don't get mush further south of 5 degrees on the equator in the North Atlantic. Both gyres in the Atlantic Basin flow west at the tropics. This probably allows a thermo-haline vortex to form causing the eastward flow between them. There must be a simple explanation for such a remarkable anomaly. The physics of oceanography indicate that the bottoms of the oceans must be full of cold water and the relatively hot water filled with more salt than anything the polar climes supply. So when dense warm salt water drops into it some sort of circulation must take place. Rather like the escapement of water in a plug hole. Given time and scope, it will evolve a unified current. Something must explain why these waters don't have hurricanes. But I digress, the focus of today's diatribe was the tracks of said storms. They seem peculiarly straight and strongly oriented westward. So what stops the majority of them moving west in the manner of storms in the higher latitudes? I wonder if it is something to do with the polarity of the North Atlantic? When the NAO is negative, there is an higher incidence of volcanic activity and the Low pressures tend to move north. Is it as simple as that? When the NOA is strongly positive, the storms move west? Is that all there is to it? So why does it induce volcanic activity instead of larger, more random earthquakes? Or have I got the cart before the horse? Do the larger earthquakes cause the gyres? |

Anyone here have a bad attack of leg cramp yesterday about 7 pm British time, maybe noon to early afternoon US/Canookistime? I had a bad attack in my left calf that is still feeling bruised. I am wondering if there is something in the earth when these things happen, as I am sure the weather is involved. Classic mid west USA one too. Nothing on here though.http://www.spc.noaa.gov/products/wwa It turned out to be Australian: An apparent tornado that whipped through open paddocks near Tungamah last Monday evening was "like something from a movie" a woman who witnessed it said. "It was just beautiful; it was pure white and this tunnel of cloud stretched from the sky right down to the ground." Bureau of Meteorology senior meteorologist Kevin Parkyn said it was entirely possible the Lawrences did indeed witness a tornado in action. "They're probably a lot more common than many people realise," Mr Parkyn said. They will go to Tungamah this week to learn more about the Lawrence family's sighting. Chris Lawrence said he had never seen anything like it, despite living in the Tungamah area for his entire life. Mr Lawrence said the twister "snaked" along the ground for about 30 seconds before dissipating into the clouds. Mrs Lawrence said Zoe managed to snap a picture on her father's camera phone just as the twister disappeared. "It was swirling towards us and then it was like someone just popped a balloon," Zoe said. http://www.countrynews.com.au/story....00712108872438 Although the time and date give it as Monday, that was the same time I had the cramp. Aus is 10 hours ahead of us. |

Aus is 10 hours ahead of us. My leg felt bruised for a day or two afterwards so if that was the storm then it will turn out to have been an F2 or something pretty close. Maybe F3. |

So do I turn the heating on again? Looks like it is going to be sunny.

In which case it might well be possible to focus this phenomena on predicting Mag. 6 earthquakes. Note to my many fans. Please trouble yourselves to read the whole shebang before you post comments on the thread. It just might make you look silly if you post derogatory comments and I turn out to be correct. But don't let me stop you. |
