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