The TSR has revised their forecast down for the Atlantic Hurricane
season. We will now see what difference the use of statistics for hard data is in supercomputers and be able to make a comparison with a slightly improved weatherlore model. Some old stuff: Tropical storms do not have to be deep or intense to drop a lot of rain. It just happens that the good old days when they were first identified as circular winds, wind power was the be all and end all of navigation. Today the main problem with them is still the amount of damage the wind can do. But in developed countries civilised ones where colonials have left a legacy that ends up in stripping the ground of its cover, the rainfall when tropical storms come ashore is more damaging. Satellites can measure heat, windspeed and sea levels. How much water they contain is pretty much a mark of the area they cover. How much water they drop is still a matter for god to determine, at the moment. And though Masak isn't (so far) an intense storm, it not only can go anywhere it can do anything when it gets there. At the moment we are in the middle of a very wet period. That is those regions of the earth that tend to get rain are recieving it in abundance this year. (Drier climes are enjoying extra sunny weather to make up for it.) So however much the storm drops, it will be too much. The water table (the height of water in the ground -how deep you have to dig to find it) is high. Wells are full, springs are torrents and there is standing water everywhere. (Odd there haven't been more forest fires reported.) When Maysak goes ashore there will be damage on a large scale. The same is true for Paloma which is heading straight for Cuba. Cuba has been hit by 2 hurricanes so far this year. I wonder how their economy is standing up to it. Last time I looked, Maysac was 120 degrees from Newfoundland and the Azores. Now here is the thing, when a sever storm goes ashore it tends to peter out. All that power disappears. But we know that there is a conservation of energy factor in there somewhere. A lot of it is tied up in adiabatics so that part is a closed loop. But some of it will go into the ground somehow. And we will have either a pair of earthquakes of some 5.5 M in the same place consecutively or a larger quake something in the region of 7 M. or higher. But not necessarily in that region. More likely it will occur some 120 degrees from wherever the storm goes ashore. We'll see. Give it a few days. It won't occur in Newfoundland a that region sparks storms not quakes. But the 120 arc runs through Baja at the moment. And that region might quake. Not that forecasting a couple of quakes on the west coast of North America is ground breaking science, to coin a phrase. But I find it interesting I think I wrote that in January of the year it refers to, whatever.. The point is since then I settled on 80 degrees as the separation required to link storms and quakes. It seemd more in keeping with planetary waves (search Rossby Waves.) Then there was this: It is about 60 degrees from Antofagasta to New York, roughly the same distance to Unimak Island from Cape Hatteras. Roughly is good enough, in that the southern reaches of the Appalachians could be given as Alabama -which is 60 degrees from Hilo, more or less. Sixty degrees is something like 1/8 of a day if you are not Esquimaux; 3 hours, 3 time zones; an interesting harmonic. If you are quick you will see that there is an High stepping off the shelf at Cape Hatteras. A series of them have run up the coast of the USA along the Appalachians (2 wide and ?14? long.) These are the remains of a standing wave that was situated over the mid west for several days this week. Appropos of nothing better to do let's have a look at these places: 24thJanuary 2008. Mag Day Place 1. M 5.8 EASTERN NEW GUINEA REG, PAPUA NEW GUINEA 2. M 5.2 MOLUCCA SEA 3. M 5.3 SOUTHERN SUMATRA, INDONESIA 4. M 5.8 SOUTH OF PANAMA 5. M 5.0 IZU ISLANDS, JAPAN REGION 6. M 5.2 STATE OF YAP, FED. STATES OF MICRONESIA These places are all pretty close to 60 degrees from: 1. Calcutta; Hilo; Petropavlovsk; Lake Qinghai. 2. Tonga; Midway Island; Petropavlovsk; Karachi; Central NZ. 3. Where the Madagasgar hurricane is; Vanuatu; Hoaria; 4. 5. 6. This was an attempt to join the dots using information from a book based on a Lunarist of the late Victorian era and the fact that the arcs of the Rockies coincide with the weather centres of the North Atlantic and are some 60 degrees or so. (I went into more detail about that in my blog but I don't have a link, sorry. The Blog is on Opera's servers and is called Quirks.) It turns out I'd made the classic mistake of confusing measurement. Distances in arc on a sphere do not translate directly as distances in unit measurements on a flat surface. So when I was attempting to make a cardboard cut-out to get a quick look see over the globe, I opened out a pair of dividers to 60 degrees, measured the distance between the points, halved it and drew a circle with that radius. You can guess what happened next. But by great good fortune I happened on the arc that described so much of North America, I kept the cut outs. I've lost them now, thrown out most likely. But I can gauge the distance. It is: 62 degrees. I suppose I could work it all out again but I can't be bothered. It's near enough. And it doesn't seem to have a great deal of bearing on the weather with regard to earthquakes. Except of course it is half way to the middle of the shadow zone. OOOH! Let's have another look at that list: High off the shelf at Cape Hatteras. A series of them have run up the coast of the USA along the Appalachians (2 degrees? wide and ?14? long.) These are the remains of a standing wave that was situated over the mid west for several days this week. 5. M 5.0 IZU ISLANDS, JAPAN REGION Micronesia also get a hammering when the Aleutians and Japanese arc is disturbed. But I can't be expected to go running after all these quakes can I? I wonder where the Izu Islands are. About 10 degrees south of Honshu I expect. |

I wonder where the Izu Islands are. About 10 degrees south of Honshu I expect. Drat. Forgot to crosspost. And splet the wrod Japanese wrog. So now a change of harmonic: I realise now the problem in finding a suitable magnitude of earthquakes is that they all relate to different areas on the planet. It has only just occurred to me that there could be more than one Rossby wave going through a region. I have always believed that storms are made up of collections of smaller fronts or waves. It is the exact same physics for wave trains and super-waves in the sea. And the physics for that has always been known. And so it is with quakes -as in fact it is with storm systems on the other side of the planet showing up with their figerprints all over the Atlantic chart, the reason for a super quake is that they all come together at once. The statistics or laws of statistics/probability all point to that conclusion too. Oh boy, I'm too good for this place. even both of them too neither. Nowall I have to do is traipse down to Exit door and humbly ask entrance to the MetO library and check it out. Yes, as if... But still. All one would have to do is check it out. Lows too as well as Highs. I'm not expecting miracles. I know it is far far easier to forecast earthquakes than to persuade an idiot he is misguided. And what's mor eif he has friends he'd rather keep and a mortgage he'd rather pay... Ah well, twas ever thus. Or not as the case might just be, one day, before I die I hope. |

![]() Weather forecast for our part of the North Atlantic 2011 Including tentative spells for hurricanes in the same ocean. Here are the phases, taken from the stuff produced by Fred Espenak at NASA: 2011. 4. Jan. 09:03 T 12. Jan. 11:31 F 19. Jan. 21:21 T 26. Jan. 12:57 W 3. Feb. 02:31 11. Feb. 07:18 W 18. Feb. 08:36 24. Feb. 23:26 F 4. Mar. 20:46 F 12. Mar. 23:45 M 19. Mar. 18:10 M 26. Mar. 12:07 M 3. Apr. 14:32 11. Apr. 12:05 M 18. Apr. 02:44 25. Apr. 02:47 early start? TS. 3. May. 06:51 W possible TS 10. May. 20:33 17. May. 11:09 F Do these or don't they. I forget. Hurricane? 24. May. 18:52 W Hurricane 1. Jun. 21:03 Hurricane 9. Jun. 02:11 15. Jun. 20:13 23. Jun. 11:48 M Hurricane 1. Jul. 08:54 T Hurricane 8. Jul. 06:29 M Hurricane 15. Jul. 06:40 Mw Hurricane 23. Jul. 05:02 F Hurricane? 30. Jul. 18:40 Mw Hurricane 6. Aug. 11:08 F Hurricane? 13. Aug. 18:58 W possible TS or SS 21. Aug. 21:55 29. Aug. 03:04 T Hurricane 4. Sept. 17:39 Fm Hurricane 12. Sept. 09:27 T= Hurricane 20. Sept. 13:39 W- TS 27. Sept. 11:09 F Hurricane 4. Oct. 03:15 T Hurricane 12. Oct. 02:06 20. Oct. 03:30 T= Hurricane though it's late in the season, so maybe a TS? 26. Oct. 19:56 2. Nov. 16:38 -w TS? 10. Nov. 20:16 18. Nov. 15:09 T TS? 25. Nov. 06:10 M TS? 2. Dec. 09:52 TS 10. Dec. 14:36 18. Dec. 00:48 W TS? 4. Dec. 18:06 M TS 5. Batten down the hatches boys, it's going to be another record breaker. ******* A lot of the above spells will be subject to the Greenland High. The ones to watch out for are the times that fall on or near the half hour if they are dry spells. And the ones that fall on twenty to or twenty past the hour are also just a dificult to get right. (But who wants to do easy jig-saws?) Allied to theawkward ones above are the hours 2 till 4:30 inclusive. I think these ones are where the Pacific storms and anticyclones dominate. I don't know much about these as I don't study their charts much. Maybe if I moved to Leeds or Devon or learned to speak Germans, things would be different. I've always had a yen to go to Canada or nowadays Russia if I could find a place in Siberia that would give me access to decent weather records. The Canadian stuff is excellent but I can't find archives. They'd send me the data if I had the shekels but god forbid I get a spare penny for things like that. I should have done it before the thieves at the banks robbed us all blind. Serves me right. http://www.weatheroffice.gc.ca/ensemble/index_e.html You can get the link of the SSPs to go back 20 days. Too much to ask them for the full 9 yards. Still, never mine. Be that as it may, what matters more than me calling the shots correctly, is that the phases run in matched sets and cause whatever natural phenomena accordingly. I've written T to indicate thunderstorms, M for misty or low overcast with some chance of slight drizzle. In the hurricane season, the M spells will have an hurricane or tropical storm. A lot -as I said, depends on Blocking -especially over Greenland. I have an idea these blocks form in a relationship to weather in the North Pacific. That ocean after all, is the supply of half the storms that eventually cross the North Atlantic. W is for wet and small letters indicate the spell could go that way, seeing as the time of the phase concerned is on the above stated cusps. (20 minutes past and to the relevant hour.) Along that line of thought, the hyphens and the = sign mean the spell could go west, .....thataway. Those spells approaching -or at- W in the season, will probably have either Super-Cyclones or just Tropical Storms. I am only guessing. But wouldn't you rather be alerted than not? 2 to 2:30 (and multiples/ factors/ ratios/ highest common whatevers of said time) tends to produce tornadic events which, in the unblocked Atlantic, is an High over Greenland with an Azores High displaced to the east. A Low from North America will travel through these corridors the day before the tornadic event. Thus it is evidence of a negative NAO. These times too in a blocked situation tend to produce tropical storms in the Indian Ocean. But I am far from certain about that at the moment. 4 to 4:30 tends to be the remit of volcanic activity on certain occasions. Blocking Highs perhaps? I don't know. I lost a lot of confidence after 2006 when nothing I said came out right. It was a few years before I got back into it with the realisation that the Greenland High was the lynch-pin. ******* Points to look for when my code goes wrong -as it will from time to time: Tropical storms will show up on the Atlantic SSP. Different oceans and different basins of the oceans have different signatures. And I have yet to put my finger on all of that stuff. When more mainstream weather forecasts go wrong or seem uncertain, it means that the excess energy in the system is being subverted subterranically. The reptiles have it.Unless wit-man speak with forced tongue. I dare say that now that I have shown the way, better people than I could take over but it seems to me that science has dug a niche it doesn't want to change -or is too scared to be seen doing actual research to do actual research. (How can you want to preserve the status quo and engage in research?) So until then, you'll just have to put up with me pottering along from one insight to the next, when and if I can. It seems terribly simple to me, no more difficult than doing a jig-saw puzzle. And I get fed up with it too easily for your own good. You've been warned. |

Anyone know where I can find online archives of these?
