Don't know what any of the symbols mean. I do think that the equation should be reconstructible to some degree with basic vector transformations; so I guess I'll be using those to figure out how this works. It would be helpful if someone with a greater understanding of physics was able to guide me through the equation. I don't understand how our oceans have basically only 1 Hadley cell if water is significantly slower than air. Shouldn't there be more water cells than air cells?
I don't know about this specific equation. What are you looking for, exactly? When I was working on Scosya, I found two very useful things that helped me figure out the circulation patterns. This article on Hadley cell dynamics, and for oceanic circulation - Ekman transport (look it up on Wikipedia.)

Didn't accomplish much. I revamped my phonology (there are a lot of phonemes I'm torn over, such as /v/ vs /w/ and /h/ vs /x/. I'm also debating whether or not to include voiced plosives.)

I also decided to make my language have a topic comment structure, so it'll probably be SVO or SOV, even though the language still follows the VSO habit of placing the noun before the adjective.)

Started a language with this phonology:

/p t t͡ʃ~ʃ k kʷ/ <p t c k kw>
/θ s x xʷ/ <θ s h hw>
/ɾ w/ <r w>

/i a ɯ ɔ iː aː ɯː ɔː/ <i a u o ii aa uu oo>
/ɪ̯a ɪ̯ɔ ɪ̯ɯ aɪ̯ ɔɪ̯ ɯɪ̯ ɯ̯a/ <ia io iu ai oi ui ua>

Syllable structure is (C)V(V)(C), where all consonants bar <kw hw> may appear in the coda and vowel sequences are limited to those given in the list of diphthongs shown above: all other vowel combinations syncopate in some way.

There's also a pitch accent (indicated by an acute) which is fairly simple in its realisation, but is also subject to some interesting morphopho, and on verbs is one of the indicaters of perfective vs. imperfective aspect.

I'm thinking with this one I'll go in for concrete verbal prefixes which look like incorporated nouns but aren't, with the language otherwise lacking noun-incorporation but still being at least near-polysynthetic. There are also three person-marking prefix series, à la Choctaw, and quite a bit of freedom to switch between nominal and verbal classes.

Examples.

saísok
sa-is-ok
1A-walk-IMPF
I'm walking

saisí
sa-is-i
1A-walk-PRF
I walked

wuúθwa
wa-úθw-a
1B-dog-STAT
I am a dog

wokúθwa
wok-úθw-a
1C-dog-STAT
I have a dog

wokkacipθírai
wok-ka-cipθ-i-rai
1C-2B-see-PRF-NEG
I didn't see you

That looks not too different from a definition of the Rossby number

Ro = v/(d⋅2ΩsinΘ)

as a function of latitude Θ on a rotating sphere (e.g. a planet). Here the other variables are the characteristic flow velocity v, the characteristic length scale d of the flow structures, and the angular velocity Ω of the body. The number is simply a measure of the convection and Coriolis forces in a rotating body of fluid. If the number is small, your flow pattern will be governed by Coriolis forces, while if it's large, rotation looses its relevance to the flow. Ro = 1 signifies that the convection and Coriolis forces are roughly equal in magnitude1.

You can get from this particular form of the Rossby number to your equation if you can assume that Ro = 1 in your system and then solve for d. However, I don't know how justified this is. I've studied astrophysical convection myself so I can't tell you what kind of assuptions are commonly made in atmospheric physics.

[1] I say "roughly equal" here since people actually use a couple of different definition of Ro in the literature. In observational stellar astrophysics the most common definition is Ro = Protc, where Prot is the rotation period and τc the convective turnover time scale. This measures the same physics as the definition of Ro given above but there is a 4π factor between their values. This definition also tries to characterise the whole interior of the rotating body and so discards the latitude factor sinΘ.

I worked a bit on Mesak kinship. I started from the premise of a Matrilocal society and then tried to figure out what that would mean for kinship terminology, and derived a kinship system that is similar but not identical to Crow kinship (making up roots as I type this out). Words are presented in the absolutive singular (the ending of which being -o-s)

taros [ˈtaɹɔs] Father, husband of maternal aunt
sáños [ˈsəŋɔs] Mother, maternal aunt

kindos [ˈkeⁿdɔs] Older brother, maternal parallel cousin♂
níȿoȿ [ˈɳiʂɔʂ] Older sister, maternal parallel cousin♀

kinddijos [ˈkeⁿdːejɔs] Younger brother, maternal parallel cousin♂
níȿȿioȿ [ˈɳiʂːjɔʂ] Younger sister, maternal parallel cousin♀
(these two are grammaticalized diminutives, formed by appending -ːi to the root. The vowel of that suffix acts differently in the two words because of the whole vowel harmony thingy)

humos [ˈʁ̞omɔs] Paternal relative♂ (includes cousins, uncles, grandfather…)
toɀoȿ [ˈʈɔɻɔʂ] Paternal relative♀ (includes cousins, aunts, grandmother…)

ɀípos [ˈɻipɔs] Son
támbos [ˈtəᵐbɔs] Daughter

kepos [ˈkɛpɔs] Maternal uncle
kepɀípos [ˈkɛpɻipɔs] Maternal cross cousin♂
keptámbos [ˈkɛptəᵐbɔs] Maternal cross cousin♀
(those last two are obvious compounds)

Among sáños (mother/aunt), the oldest (who will inherit the household once her parents die) and her husband are referred to with a honorific suffix -kun "first" (transparently derived from the number one) to the root, yielding sáñgunos [ˈsəᵑgunɔs] "first mother" and tarkunos [ˈtaɹkonɔs] "first father". Sometimes the same suffix may also be applied to their children, especially after the household has been taken over by their family. It is also (a fossilized) part of the stems for grandparents:

túñggunos [ˈtuᵑgːunɔs] Maternal grandfather
bikkunos [ˈɓekːonɔs] Maternal grandmother

Made a chart too:

At kveldi skal dag lęyfa,
Konu es bręnnd es,
Mæki es ręyndr es,
Męy es gefin es,
Ís es yfir kømr,

I'm still a little bit unsure of how this works; How are you to determine the flow velocity and the characteristic length? At least, what are those variables on Earth?

The Wikipedia article gives some illustrative examples (from tornadoes to ordinary low-pressure systems). Different flow phenomena work in different scales and so they have different Rossby numbers. When calculating this, you need to select the characteristic values accordingly. In the atmospheric context the characteristic velocity would be the typical wind speed in the system you are looking at and the characteristic length scale the size of the relevant circulatory flows, such as convection cells or the diameters of tornaroes or low-pressure systems.

Do I understand correctly that you'd want to solve for the characteristic length d in the equation, provided that you know the rest of the variables? In principle you can try this and get some useful ballpark estimates for your circulation cell sizes. I'd be quite cautious in doing this, though. First of all, I don't know if there are any good arguments for assuming the value of the Rossby number for using in the calculations. At least provide us some citation that you can safely assume a certain value for a given atmospheric phenomenon. Secondly, the Rossby number, like other similar dimensionless numbers, is not exactly geared towards getting you decimal points worth of accuracy when actually used in calculations. Remember that the characteristic scales are exactly what they sound like, good representative values given to some parameterss that can in reality have a quite considerable ranges of variation. So just be careful and don't overinterpret your result.

For background, what the dimensionless numbers, like the Rossby number, are really good for, is comparing the terms of complex equations with each other and checking which of them might dominate over the other ones. If such a dimensionless number has a sufficiently large or small value, it can mean that you can safely forget some terms when solving difficult equations and hence significantly simplify them. As a result, dimensionless numbers are also useful for pointing important changes in the behaviour of various physical systems. A classical example is how the value of the Reynolds number relates to how fluid flow transitions between laminar and turbulent.

I've got a name for that Algonquian language I'm making. The people are going to call themselves the Akatanišono, if they don't refer to themselves by the name of their band, while the language will be called Aθošaašó "We speak thus". There's also an exonym, which is currently Les Acharnés "the Fierce Ones".

Been working some on a grammar of Tirina. I keep going through this cycle of sitting down to write a section, thinking I need some inspiration so I go pick a few grammars at random out of the Grammar Pile, getting depressed because MAN real-life grammars are SO IMPRESSIVE compared to the piddly amount I've written about Tirina [:'(] [:'(], and finally managing to scratch out a few sentences. Finally making some progress, though! [xD]

At some point I probably will post some of it, but at this point I'm just trying to get a basic sketch down, and flesh it out later. Started working on personal pronouns today, though.

Have you posted anything about this language here on the CBB? If not, I'll have to read about it over on the other board. What's the etymology/meaning of Akatanišono?

No I have not posted here about this before except in an earlier post on this thread a couple of pages back to say that I had restarted it. I should get round to putting more stuff on it up here, but there's already so much on the ZBB that it would be a simple copy and paste jod for the first few sections.

Akatanišono, as it says in the thread, simply translates as "Our (incl.) people". EDIT: it is derived from the PA *keterenyiwenawa

Well, I decided to settle with a three vowel system: /a e o/, so I have some sound changes to do. I might make it a six vowel system (Spanish vowels plus schwa) and have vowel harmony based on height.

As for /a e o/, I'd imagine there'd be some allophony with them.

Thoughts?

I had the idea of having a gradual introduction of Dark Magic/Dark Arts™ to students of the Arcane Arts at Zerzhém university:
Bachelors: Only Defence Against Dark Magic (to not lead the students into temptations at a young age*)
Masters: Selected Dark Attacks and Curses (experienced users of magic get access to a select bibliography of the Arcane Library's Dark Arts section)
Doctorates: These professionals get full access to the Dark Arts section for their Doctor's Thesis and for research later on.

The typical entry date to University in the medieval society of the Urland is about 16 years of age (17 in the West-Cheruscan Kingdom on an island further west [;)] )
The Bachelor's degree is not finished before the age of 20.
Languages of Rodentèrra: Buonavallese, Saselvan Argemontese; Wīlandisċ Taulkeisch; More on the road.

Ah, I see. To be fair, though, it looks like it says that relatively far down in the thread, and I haven't had a chance to read through it yet.
