Midnight Friday according to the model run on the linked site as of: Forecast for 06:00 UTC on Tuesday 4 December 2012 promises to begin a massive storm. It begins with an injection of precipitate from South America on the evening that spell starts. Which ocean I can't say. |

According to: http://www.tropicalstormrisk.com/ Three is only going to be a TS and then dissipate after 72 hours. But isn't that how Bophar started? |

The Japanese quakes may have takes the sting out of the storm but according to: http://www.bom.gov.au/australia/char...Refresh+ View ....the storm continues unabated until midnight Sunday/Monday the 9th. Just like the weather charts say. Except that there is a drastic change on this one: http://www.weatheroffice.gc.ca/ensem...me=00&Type=pnm It has been corrected (one way or another) for the seismic activity we have had of late. I have no way of knowing what the Australian stuff is running on. Memories perhaps? |

It has been corrected (one way or another) for the seismic activity we have had of late. I have no way of knowing what the Australian stuff is running on. Memories perhaps? This signal series went: Virgin Islands, California, Hawaii and Japan I must try to remember that. It's a blooming nice day here. The snowbirds will be posting their silly heads off in uk.sci.weather, probably wondering what's going on. It will be revealing, if not quite as interesting as it was. Meanwhile things in Antarctica are just like the old days. An exceptional input of blue on that chart turning into a dark disc presages a large earthquake. I believe the chief difficulty in the region is that the harmonic changes drastically with the seasons. In summer when the sea ice is extensive, the cyclonic weather can reach an acreage that exactly matches the surface of the sea still liquid enough to support cyclones. Weather stations along the south coasts of Africa, Australia and South America need to be supplied with sound monitoring equipment. I dare say that there is suitable research into sub Antarctic ice already. Unfortunately, this will all be in the secret repositories of agencies that want £30 and more for the privilege of not being able to understand what they will let you read. Coupled with the winter ice melt, the Polar Low is diminished from November on. None the less, Anticyclonic weather still has difficulty traversing the constriction at 50 West. And that is where this signal appeared. So why do all the signal precipitation anomalies fail to reach the continent? Obviously in Winter, despite all the ice having melted in the sea, the continent is still a formidable barrier to the Low Pressure areas. This despite the fact that at "Sea Level" the Anticyclone called the Polar High is only 1000 millibars or so (1010 mb at most.) |

Issue day 8 Forecast day 9:
http://www.weatheroffice.gc.ca/ensem.../cartes_e.html It looks like another one to me but it may have just been this: 2012/12/08 5.1 M. @ 19:00. 7.2 S. 144.0 W. S. P.N.G. 5.7 M. @ 16:35. 7.2 S. 143.9 W. S. P.N.G. Pairs and triples like this occur with the demise of a large storm. But this aftrnoon before the sky filled with lower cloud I saw some pretty extensive "Mares' Tail". Cold snaps, frosts, heavy dews and Mares' Tail (high ice cloud in a blue sky that looks like whisps) all indicate tropical storms. Mares' Tail clouds, the most severe of them. This was a pretty large example of that phenomenon. http://www.bom.gov.au/australia/char...Refresh+ View is still running true to it's earlier form. And it doesn't even break cleanly. Sunday/Monday at midnight it comes apart. In the North Atlantic it will look like a pretty divisive break up of whatever is in it at the moment. But I think the chart tomorrow for the North Atlantic will be full of pink mice. Occluded fronts that mean lots and lots of quakes. It beats me what the hell they mean with this thing: http://www.metoffice.gov.uk/public/w...ime=1354816800 Just playing with the new web pages probably. There have been lots of complaints with the Met Office's output over the last few months. For some reason they always seem to generate problems when they set about fixing things that ain't broke. Talking about breakages I just cobbled an old drive and got back a collection of their tropical storm data which they deleted from their online site some time ago. So that was an unexpected gift. Not that it exceeds what is available on the Unisys site. So... On with the game. |

This still looks like it has potential for another 7.5 or so: 036h sea level pressure forecast valid on Dec 10, 2012 12 UTC. http://www.weatheroffice.gc.ca/ensem...me=00&Type=pnm Breaking by: 036h sea level pressure forecast valid on Dec 11, 2012 00 UTC. What we need now is model turpitude and no more Mag 5s or greater. The tropical storm fronts seem to be up for it, though the North Atlantic is showing signs of duality. Pity that. Still; never mind eh? |

Only a 7.1 but nobody's perfect. And like I said elsewhere, I don't enjoy the references others have to work with. Set levy! Well I'm blowed the North Atlantic Chart from the Mess OfThis has an analysis chart out showing the likelihood of a severe earthquake sometime before publication. Well done the British Government. And well done the boys in the back room for at least preparing the useless article. Not easy for you I am sure. Surface pressure chart - Analysis Issued at: 0600 on Mon 10 Dec 2012 Forecast chart (T+18) Valid 3000 UTC Mon 08 Dec 2012 That's what it says. The third chart is a forecast: (T+12). Yet the legend on it states that is is: "Valid 0000 UTC Tue 11 Dec 2012. I'm better at forecasting earthquakes than I am at maths and I am not exactly brilliant at forecasting earthquakes but even I can spot a discrepancy. I suppose it comes with having an eye for anomalies. Which kind of takes the wind out of my sails for the last chart in the series today at the location linked. It does indeed show another and yet more significant bout of severe weather on its way. And this is how it works: As previously stated elsewhere frosty weather; snow; mists; etc.; etc., all betoken the likelihood of tropical disturbances, nee storms. And with frost on the slates and car roofs here in sunny Stoke this morning, I was expecting something promising but discarded it as the present storm was still a Cat 3. When a large cyclonic system appears in the North Atlantic it generally indicates a Tropical Storm which then goes on according to the situation and extent shown in the North Atlantic, to be an hurricane. Usually. As seismic disturbances follow along storm front lines, the chances of a large earthquake occurring are likely where two or more such fronts meet and "end". The charts on the above link were still showing the preposterous 3000 UTC Fri 06 Dec 2012 chart at 5 am this morning ( 10 December 2012) so I had stopped looking at the damned thing. (Fortunately they still publish the sensible one he http://www.metoffice.gov.uk/weather/..._pressure.html 7 hours late and 30 hours short as usual but at least as accurate as the best of them.) Anyway it is now showing a large marked Tropical Storm gathering in the same place as for Bophar at T+60 after coming apart as stated (also in another thread.) (I'm not speculating on the Latitude and Longitude; not even on the ocean.) I actually got that from the BOM charts which, incidentally, don't show a new storm budding -although they might be showing a resurgence in the present situation. |

Three in a row across Canada again but they are wobbly and there is an anticyclone on the west of it. And it isn't as straight as it might be. http://www.weatheroffice.gc.ca/ensem.../cartes_e.html It all depends on how many Mag fives we get between now and tomorrow evening. |

What I saw filled the sky, or rather, most of the part of it in the direction I was looking. I believe that behind me it was that stark, cold blue of anticyclones in Winter in Britain. What I was looking at was just the front edge of one of these striations: http://www.woksat.info/etcul09/ul09-1300-b-uk.html And this is what it looks like to a demi-god: http://www.woksat.info/etcul09m/ul09-msg-1200-uk.html How small we are and how infinite is the majesty of its creator. And yet, little as we are, what we see is what we get. It works beautifully for man and beast. And thanks too to Bernard Burton who will provide these images on disc for a very small fee. How hastily we thank men when we owe so much to the one we hesitate to praise. |
