Temperature: Isotherms & Hot/Cold Spots - Worldbuilder’s Log 34

[@rossbaygeo]

Thank you for the shout out @artifexian; I've had such a great time contributing to the worldbuilder's log! If any viewers have questions or clarifications about the guide, please respond here so for a response and if necessary it can be updated.

[@Lilas.Duveteux]

Won't the large chain of mountains create a cold spot ?

[@rossbaygeo]

Hi @@Lilas.Duveteux , altering temperature for altitude is the very last step and will use the elevation map viewers would have made while following along with @artifexian.

[@dylaneverett4586]

My marine biology professors described the shape of the warm equatorial ocean waters as the “warm tongue that sticks out towards the east during el niños and retracts back to the west during la niñas.” I think i prefer the nozzle idea lmao

[@kie927]

Bro 😭😭

[@alpal4245]

I like the professor's vocabulary. We can only be doing real science when we start licking things

[@Lilas.Duveteux]

If this was a high fantasy verse, here I would put the agricultural zone, based on all the information about this world: Buckwheat and rice in the sea of Jannar, Oats, barley and prune near the South East Coast of Erzi. Oats, cedarnuts and nothern wild rice (perhaps domesticated) North West coast of Erzi, Wheat, West coast of Erzi, more Southward Rice, breadplant and coconut on the equatorial East Coast of Erzi Shortgrained rice and Wheat, very tip of the South-East of Erzi Wheat and millet, Degra

[@allankokkonen5722]

Nice indeed! My contribution: the tropical mountainous regions of Southeast Ezri or Western Jannar or the Northeastern highlands in Picard seems like ideal hotspots for corn and potatoes. Rainforests in the Southmost parts of Jannar might be the birthplace of bananas and tropical spices. Also, I can see some meditarrean-esque region in the smaller 'arm' of Picard, which might be suitable for horticultural crops, such as lettuce, brassicas, olive and citrus.

[@Lilas.Duveteux]

@@allankokkonen5722 As high fantasy, so many cuisines. I imagine that the sea of Jannar would probably have a single-pot based cuisine of rice and buckwheat, with plenty of fruit (fuiting trees protect crops from winds and make bees necessary for buckwheat cultivation healthier by varing their diet). A hotbed for apiculture, similar to what is found around the black sea. Mushrooms would be quite the condiment, especially in more northern regions, as it prefers cool, wet climates and complements flavor-wise buckwheat. Smaller quantities of fish, mollusks, shellfish, kelp and seaweed would complement the diet perfectly for proteine and vitamines. The basic meal preperation would be a variation of pilaf or kasha mixes, perhaps with some pickeled and steamed vegetables or fruits as side. Closer to the ocean, they might enjoy more seafood. South-East coast of Erzi (with the mountains going west to east) would have a slightly cooler climate and quite plenty of fish available. A diet of oats and barley would mostly be eaten as bread (baked or steamed) with a side of salted prunes, but also cherries, raspberries and blueberries could be consummed. Most proteine would be consummed in the form of conniferous nuts and sealife. The basic meal structure would be a slice of bread baked or steamed on which various foods would be added on top. Lactic fermentation and smocking would be the prefered preservation methods. Most meals would be eaten cold. NorthEast of Erzi would have a diet of stewing, often times single-pot recipies of toasted cedar nuts, oats or rice as the main grain. When meat and fish is available, it'll also be cooked in this manner. Flatbreads would be a popular dish, as it is easy to transport and store. Oats would be the food stable, cooked into stews and breads, while rice would be a purely summer treat, often cooked with berries and nuts.

[@wilhelmseleorningcniht9410]

@@Lilas.Duveteux ooh are bees particular associated with buckwheat? I know traditionally at at least among the Pa Dutch in the US, historically speaking poorer folks would usually grow buckwheat and keep bees but I'd not heard about one being necessary for the other (except in so much as bees need flowers of course)

[@Lilas.Duveteux]

@@wilhelmseleorningcniht9410 Yes. You need polinators for all those flowers, plus more flowering plants tend to be planted around buckwheat fields to protect crops.

[@funwithmadness]

I might be confusing this with a different software package, but doesn't Illustrator have some sort of "morph" tool that extrapolates shapes based on a start and end shape? Could you use that to create your isotherms?

[@Jpteryx]

You don't even need that tool. Just click and drag the shape vertically to make it flatter the closer it is to the pole. This will make the isotherms more like perfect circles the closer they are to the pole.

[@CuriosityCore101]

This is so interesting!

[@idle_speculation]

It’d be interesting if you tried using clima-sim to generate isotherms and compare them to the by-hand method. It’d also be a good way to talk about the strengths and failings of popular softwares for climate stuff.

[@ldelgg]

HECK YEAH

[@martiansky923]

Make an addon for SpaceEngine, it's easy. It allows us to see your star system in 3d. It allows to apply premade maps, but also supports procedural generations for secondary planets, that are not likely to have own map.

[@Beeontree]

I don’t see the temperature chart in this planet section, how do I access it?

[@GrayderFox]

Ah...not sure I quite get what hot and cold spots are meant to be. Interesting, though! This seems like it's all going to come together in a super-interesting way. :3

[@rossbaygeo]

Hi @GrayderFox, the Hot and Cold Spots in the guide are abstractions of different phenomena that cause relative increases and decreases in temperature from what one would expect based on latitude.

[@GrumpyKaiju]

Why every 6 degrees and not every 5?

[@rossbaygeo]

Hi @GrumpKaiju, 6°C is both manageable with the number of isotherms to manipulate, and useful for eventually modelling climate. We also have some later steps that are built around the 6°C isotherms. After you complete the guide, you can use whichever scale of isotherms that you prefer.

[@fernandorevilla3518]

"simplicity"

[@grahammacklin1457]

Thank you for a great series, it is such a cool way to learn about how our planet works (and how others might as well)! One thing I am a little confused about, though, is your labeling of all "hypercontinental regions" as cold spots, not just winter ones. I understand why continental areas are extra cold in the winter (land surface temperature changes much more rapidly than ocean surface temperature), but I am confused about why they are also extra cold in the summer. Can you provide any intuition for this?

[@rossbaygeo]

Hi @grahammacklin1457! For completeness to illustrate where Cold and Hot spots are placed, @artifexian demonstrated where the Continental and Hypercontinental Cold Spots are located on Cretak. When we move to the last video, Continental and Hypercontinental Cold Spots are only 'activated' in the winter. Edit: the effect we are trying to model for the winter in Continental and Hypercontinental zones is a concentrated drop in temperature at the centre of the zone. The summer effect is much more generalized across the entire Continental or Hypercontinental zone.

[@garlikbred6474]

Unrelated to the video but- Is it harder to find Artifexian on your feed? I havent been recommended him as much, even though im subbed. And people seem to be finding his videos more slowly (As in, views and comments are increasing slower). Im just curious if anyone else has noticed this?

[@Ratchet4647]

He hasn't been messing with the shorts cash cow, so KZbin is sending less traffic his way. A lot of channels have seen similar issues. Additionally, some previous viewers weren't into the new series and have fallen off over time. That can affect engagement and, therefore, the algorithm.

[@Asterrrtjee]

The fact that I'm watching this at 13 years old knowing I'm gonna be at least 15 when the series is done is crazy!

[@Rowbotftw]

so exited for the next episode

[@AaronGeo]

[@wednes3day]

for the waviness of the isotherms in relation to the poles (~8:13) .. it feels like that should also be doable in 2D if you transform or average the isotherm closest to the poles into a more or less straight line, remember how much you transformed it by and squish the others proportional to that

[@ATOM-vv3xu]

I hope sometime in the near future I can finish my heightmap so that I can catch up

[@triplecheeseburger6468]

Do you have any plans for making a discord server or something for this project at some point?

[@garlikbred6474]

A discord server would be so fun!

[@Ratchet4647]

There was a subreddit for the channel back before this series. I figure it still exists.

[@madelinejameswrites]

Absolutely fantastic. I love this method.

[@bergels9408]

I've been waiting since the last one!

[@baptistemulton7728]

It's been a few months since I started building a world using this series, and I'm finally up to date! Now I can't wait for next video and the following ones, climates mapping feels so close!

[@kadenvanciel9335]

What’s next in line for this series?

[@AaronGeo]

Climate, I presume

[@Jpteryx]

Just as a note for viewers, a cold, low-axial-tilt, fast-spinning, and/or large planet will have a greater equator/pole temperature difference; while a hot, high-axial-tilt, slow-spinning, and/or small planet will have a lesser equator/pole temperature difference.

[@kie927]

What causes that? I would think that a slow spinning planet has less even heating between the day and night side.

[@Jpteryx]

@@kie927 Correct, but it will also have more even heating between the equator and the poles. That's because there's less of a Coriolis effect and winds will be more easily able to travel straight from the poles to the equator.

[@kie927]

@@Jpteryx Ohh that makes more sense, hadn't considered the Coriolis effect

[@wurfelumdiewelt5301]

Awesome and informative video as always! :) Thank you for your hard work! Whats the current midterm plan/todo list for this project? What topics can be expected?

[@Diesalot-sc9qz]

I think he read out his intended plan in the first episode

[@theoriginaldrdust]

perchance

[@morgan0]

8:15 another way you could think about this (speaking as a casual observer), is that as you get near the poles, there is less air in any ring around the polar axis, and even if the temperature could change the same amount from place to place at that scale, there's simply less space for it to have equally significant large scale variations

[@lumiauroras6741]

Is the latitudes/temps table in the Worldsmith document? I can't find it!

[@oddscomedy7128]

What about planets with a higher axial tilt than 40 degrees? Does the itcz replace the 40th pararell? Does another isotherm replace the 40th pararell? Or does the avg temperature stay on the 40th pararell?

[@davidbornemeier856]

Thank you for the video!

[@daniel_rossy_explica]

I am so far behind that I think that I have abandoned my project entirely. The continental drift broke me, I was able to keep up with the videos until then.

[@Pharry_]

guys i wonder if hot and cold spots is a formal term

[@Dracos_Productions]

absolutely love all of your videos on how to do this, i finally got to the stage where im starting my simulation, however ive found an issue with gplates where my mouse is offset from where im actually clicking, ive no idea on how to fix that though or why its doing it

[@ATOM-vv3xu]

Will you go into el niño events and such?

[@rossbaygeo]

The temperatures, precipitation and therefore climate models in this series focus on averages. When geographers make climate maps we tend to use climate normals, which average temperature and total precipitation over 30 years. Within that timeframe, climate phenomena like the El Niño tend to be averaged out-depending on the frequency and intensity.
