# How hard is it to read a weather chart?

I would have thought a reasonably well educated child could do it. …

Just look at, for example, this one:

The above is drawn from actual data from all the weather stations that report to Britain’s Met Office.
The following one is a computed model (C_O_M_P_U_T_E_D – M_O_D_E_L) run based on the data given for the above:

Is it difficult to make out the centres of fine weather or storms?

Hint:
They are indicated by a system of concentric rings.
Both Lows or storms and Highs or calms are denoted in the same way.

Can you find them on these charts?
Look carefully (keh-foo-lee, C_A_R_E_F_U_L_L_Y)

Now look at the central ring some distance down from Greenland (2 blocks -or map squares, to the left of the one Britain is in.)

For the analysis chart (the t-o-p- -o-n-e… (woh oh nh)) the concentric circles go up (U-P uh-ppuh, UP) in pressure. That means it is an H-I-G-H say it after me: Hi. Hah-ee!

The rings in that region on the next chart go down (DAH UH OON) in pressure as the rings get smaller. That makes it a L_O_W. Lo. L-Oh!

How hard is that to learn?

***

That was the hard bit. Once you get over the problem of having to look at things, you can recognise (REH-COH GNAIZE) similar set-ups all over the charts. Some of them have different degrees of difficulty with them (WIH UH THU, THU UH EMMM.) They may have a different background that puzzles you (Y_O_U, EE-OO. Say it children.) They may have other information in them. Maybe words like “High” or “Low” or even letters like “X” in them.

But even they are comparatively easy with practice. Practice children. Look at them now. GO!

***

The next thing you need to learn (LURN, L-UH-NNN) is that the centres of these systems move across the charts. You can work this out by following a sequence of them. It works best if you use the sequence given by the Model Run. M_O_D_E_L – R_U_N. Say it out loud. It doesn’t even need phoenetics to help you.

If you get hold of the entire output for that shift, you will be able to see them marching across the pages like a cartoon.

***

This is the easy bit:

When that doesn’t happen, we call it an A_N_O_M_A_L_Y. (Ann-ohm-ah-lee. Say it: ahnohmahlee.)
And when that happens children, you find that a great big nasty old earthquake has struck.
(Earthquake. Uh rr th kw ay ck.) That IS a difficult word isn’t it?
Never mind, practice makes perfect.

Look, here comes a nice long list to practice on:

Now then kiddie-winks. This is where you need to put your thinking caps on. Are you ready?Then I will start.When we have an anomaly (ah-noh-mah-lee) we have a BIG earthquake (ur-th-kw-ayke.) And so it was, just like we were warned:See: 7.1 Magnitude at Mindanao, Philippine Islands.There! Wasn't that easy?And just in case you don't realise what a bunch of gonks you all are, here is part of that list again:

Now then munchkins; which of us can see any large quakes that occurred an WHOLE DAY (D_A_Y) before it?That's right, children.NONE OF US!!Isn't that interesting (I_N_T_E_R_E_S_T_I_N_G) ?Now clap your hands, you idiots.

I can't believe that that is the only typhoon or hurricane that will be winning our attention then, so hang on children, Wednesday's child has far to go.2013/10/16 12:46. 6.4 S. 154.9 E. 5.3 Mb. BOUGAINVILLE REGION, P.N.G10:31. 6.5 S. 154.9 E. 7.1 Mw. BOUGAINVILLE REGION, P.N.G.Sometimes you get the bear, sometimes the bear gets you.When a large storm dies a large quake tends to occur. I've been looking at bow wave shock with bullets running through water. It appears that the production of cavitation is responsible for an harmonic distribution of this bow wave phenomena.Now I am wondering if an acoustic wave itself could produce such a phenomenon. If it could that would explain solitons called: "Swell" as well as the convergence we call large and super-quakes.I am pretty certain that that is the way research must go if anything is to succeed my efforts with this stuff. Large earthquakes will follow large typhoons only if the large typhoon is in a central part of the ocean.This is because the acoustics formed or forming it all will be filling the ocean basin involved. The physics is that of the Tunnel Effect that is studied as Doppler Effect at present. The mistake made with current explanation is that the carrier wave has to be set up before the so called shift in sound can take place.In other words the acoustics have to have filled the basin before the next change of phase takes place.

4. Weatherlawyer says:

It would appear that the three lows in a row effect are only caused when the acoustics of the basin concerned reach the equivalent of 666 in the change of state phase.Another way of looking at it is from the point of view of a mass dropped into a reservoir. If the drop takes place in the centre, the vibrations are thrown out equally in all directions.The next disturbance will take place wherever the dynamics are interrupted. This is taken to be an obstruction such as a solid dam of some sort. But it might just as easily be an acoustic obstruction or whatever the opposite of an obstruction might be… an enhancement?Two Lows in a row produce a medium magnitude earthquake. Three lows in a row produce a large earthquake and presumably 4 lows produce a super-quake.There are 4 Lows coming up on the NA EFS charts. From the forecast given on thew 16th October 2013 the super-quake will take place on Saturday IIRC. I will go and look it up. And of course post it on where the hell ever I feel like posting it on you bunch of dummies.

5. Weatherlawyer says:

It had already occurred to me that the International Convergence Zone (the meteorological equator) was rapidly approachingf the gfeographical one and that soon, the harmonic that causes tropical storms would be most effective in the southern hemisphere.So now I am wondering just how much the Hitler's Bunker Effect there is involved with the acoustics of oceans. There is something related with lunar phases and the reproductionof coral or some such annual cycle too.The mating relies on a certain phase of the moon and it has to be in October, that means that it takes place a week later each yer then returns to the first week in October every 5th year. (Or however the cycle of phases runs.)(Generally speaking a month that starts with a new moon one year, will stat with a first quarter a year later. Full moon will be the start of the month in the next and last quarter the next. This is a generality that applies to all months because a month is 30 days long but the time between phases isn't.)(But it isn't that simple either.)

6. Weatherlawyer says:

So as a recap we have the bullet passing through water causing a stream of cavitation.And this leads me to believe that cavitation can cause cavitation.Meanwhile the time limit for the duration of an acoustic background large enough to cause convergence of all the sound in a place where cavitation can occur is running out or… hitting a sweet spot. All of which is signalled in the various weather charts. It's all quite simple really once you can see it. Until then…Not.
