The tornadoes and earthquakes of the spell starting 25 April, 2013

It's almost over by now but then it was always going to be over one day, wasn't it?

I will add the pictures at another date, my time is running out on here today. …

The small Low off Newfoundland on the MetOffice’s North Atlantic chart as of Sunday, 27 April, slips between two large Anticyclones (Highs) in the west of the North Atlantic by late Monday the 28th.
On Tuesday everything changes.
The large cyclone (Low) over Iceland moves ashore at Norway. There is a lot of occluded frontage on the charts for T+72; which, along with the making and breaking of set-ups portends seismic activity.
The North American EFS shows a set of Lows spread across Canada on the 27th April chart for the 28th. There is an almost unfailing connection with a line of Lows there and large seismic event elsewhere. The set up on the 28th however, is not a straight line on the chart. And there is a noteworthy relationship between earthquakes and tornado cells, where one seems to displace the other from time to time.

The following day the same model run shows there are just two Lows on the continent. This generally means that there will be a medium sized quake, something like a 6 to 6.5 Magnitude one. But again, there is a caveat. Out in the Pacific just off the chart, there appears to be another Low and this one makes it three in a line.
I am not familiar enough with the chart source to be more definite about the behaviour of the things yet.

The southern hemisphere pictured by the computers at BOM, Australia shows a not very convincing forecast for tropical storms. The cartouche is when a streamline around Antarctica forms with the 1016 millibar line running most of the way around the continent more or less following the outline of the place.
What throws it out is that the isobars hold two or three large weather systems that cause elongation. In fact I don’t think it ever really gets going, thanks to a mid Indian Ocean storm from T+36 on and another storm to the east of Australia over Santa Cruz.
This “nearly” storm (shown as a Medium threat in the Joint Typhoon Warning Centre’s image: ABPWSAIR (27/060 0Z)) follows a similar pattern (through the anticyclone in the Pacific Ocean) quite clearly seen from T+120 on.

After that, things go quite pear shaped with the rotation of storms around the Antarctic continent resembling the coils on the stator plate of an electricity generator (from T+150 on.) It will be interesting to see if this state of things is from where the development of tropical storms in the Northern Hemisphere can be said to occur. I have a feeling it is a semi annual condition. I can’t remember how long it lasts though.

  1. Oh Ye of little faith.I will never doubt the charts given by the Australian Meteorological Office again -until the next time.This is what they said to me about Zane:From a long time before it occurred: the following was typical of the isobars around Antarctica. This is the chart from 06:00 on Saturday the 20th April 2013.As you can see the outlines of the 1016 millibar isobar is all over the place. The biblical term is “ruptured”, you can call it flatulence if you like.Things look somewhat more smooth by T+84: The 23rd is the likely date for the next tropical storm -if the 1012 mb line is anything to go by.It actually looks quite cohesive on the T+126 chart: If it wasn’t for the dark masses of precipitation in there I’d say it with certainty. But that stretch from 80 Eat to 120 West looks far to eruptive and full of earthquakes. And I don’t know, there is just something too leading for me to be convinced. IIRC I was looking for the channel south of Africa to get blocked and wondering what the situation would be with the first of the Northern Hemisphere storms.(Would you believe I had no idea what was happening along the full length of the Mississippi at that time?)Now take a look at the dark masses between 100 and 160 East: For a tropical storm the incidence of large earthquakes is low. Of course there are plenty of medium sized ones all the time, taking up the slack in the sun’s energy transmissions. (Earth is a really nicely balanced machine if you take the time to throw out all the guff from climatologists, evolutionists and other ne’er do-nothing-useful, berserk, doom sayers.)Obviously the pattern holds good for storms in general seeing as there were still some pretty awesome fireworks going on in the parts of the planet not normally considered tropical. Can we have topical storms?And even more; extra topical storms? The term LOW in this picture refers to probabilities not cyclones per se. Zane just the day before was called an “HIGH”. Here is the first indication it would come: It’s as smooth as any and I was convinced there would be something going on in the Northern Hemisphere by now. The only fly in the ointment is the very large cyclone between Australia and Antarctica. I had been caught by that sort of thing before. It was large enough to hide a large earthquake in. Something like this one perhaps:2013/04/266.2 M. at 06:53 in the Kermadec Islands.But that was shown up on here somewhere: I don’t know where; geomancy is not a forte of mine. 60 or 120 east obviously. The one at Kerguelan Island is about 80 degrees or so from the epicentre. (The nearer on is some 50 degrees away.) I don’t know what else I might be missing it (I love the logic of that statement) but it seems to me that earthquakes redound in the opposite spin to those of storms. While most storms seem to track in, on an equatorward trajectory, making an angle of 120 degrees from their line of precipitation, earthquakes may be travelling in a polewards direction, forming an angle of what? Is it too much to say 120 degrees of deposition or havoc? Something unseen then: Leviathan.I think Britain’s coming experiences with Gas Fracking will be able to tell us an awful lot. (Probably to our detriment initially. But it will be nice to see how the Tories will spin bad news in a proletariat that is nominally socialist (though not inclined to vote for anyone.))To be continued.This is what Unisys has or had to say about Zane:“Tropical Storm ZANE 30-30 APR 60” (Knots) From their legend:“Tropical Storm TS —– 34-63 39-73 Yellow”(A) Tropical Storm (is categorised as) TS (and has wind speeds between) 34-63 (knots) 39-73 (miles per hour and is indicated on their charts with a) Yellow (line.)

  2. From Midnight Sunday to T+84 Noon Wednesday the 1st May there is a pretty much non stop active tornado cell flowing west to east.There was nothing on the NWS chart at noon Sunday the 28th April but that might have been a fresh chart. There was certainly activity on the chart from the previous day.If my aching back is anything more than too much sugar and a generally poor choice of food over the last few days, then there is little else to go on for the above. Greenland maintains an anticyclone and the one in the middle of the ocean moves over to allow that cyclone free passage.It flows from North America to the North Sea in a straight line, virtually unimpeded by anything. No hesitation, nor nothing over the Mid Atlantic Ridge. At T+84 on the BOM chart for the southern hemisphere there is a three point Low on the coast of Antarctica south of Africa that fits the triple weather front on the North Atlantic chart. The latter does not look like providing a great deal of seismic activity though. Three adjacent earthquakes; who knows where, so close to one another chronologically speaking that they count as a swarm.I don’t even know if it is earthquakes or something taking place in a volcano. At T+126 they hold a black mass, with all that that entails.Don’t even ask. At this time of year the Antarctic charts become a little obscure to me. Fair play, it isn’t as if I can interpolate them from any previous charts in the same week.Can I!29 April 2013.Abpw10 pgtw 290600 msgid/genadmin/joint typhoon wrncen Pearl Harbor HawaiiSignificant tropical weather advisory for the western and /south pacific oceans/290600z-300600zapr2013// ref/a/msg/joint typhoon wrncen pearl harbor hi/282221zapr2013// ampn/ref a is a tropical cyclone formation alert.// rmks/1. Western north pacific area (180 to malay peninsula):A. Tropical cyclone summary: none. B. Tropical disturbance summary: none. 2. South pacific area (west coast of south america to 135 east): A. Tropical cyclone summary: none. B. Tropical disturbance summary: (1) the area of convection previously located near 12.6s 153.6e, is now located near 12.6s 153.3e, approximately 505 nm east- northeast of Cairns, Australia and is the subject of a tropical cyclone formation alert. Recent animated multispectral satellite imagery shows the system has maintained overall organization although the central dense overcast feature has become shallower. A 290513z ssmi-s microwave image shows formative banding albeit with fragmented convection. Upper-level analysis indicates the system is under a narrow ridge axis in an area of low to moderate (10-20 knot) vertical wind shear and good radial outflow. However, just 05 degrees to the south are strong westerly winds with shear values greater than 25 knots. Sea surface temperatures (29-30 celsius) remain favorable for development. Maximum sustained surface winds are estimated at 25 to 30 knots. Minimum sea level pressure is estimated to be near 1000 mb. See ref a (wtps21 pgtw 282230) pgtw for further details. Due to the favourable net effect of the environment, the potential for the development of a significant tropical cyclone within the next 24 hours remains high. (2) no other suspect areas. //

  3. That last post was full of pictures but I suppose I could have put them in all the others too. I will do it later.There is another spell due tomorrow it is much the same if not more intense for Britain. Of course there are so many ways that can all go wrong:
