The Köppen–Geiger climate classification made simpler (I hope so)

Actually I'd say the southern Andes having such a drastic effect is the abnormal case here. Normally you'd expect cyclonic rainfall to not be so heavily affected. It's maybe a slight error in perception to view the regions that are affected by the westerlies as being constantly swept with moisture-laden westerly winds. In reality they are a belt of localised low pressure centers that circle the globe on a west-to-east vector (more-or-less), so the winds tend to be predominantly westerly when viewed globally, but not necessarily locally.

I suspect Patagonia has an unusual local wind pattern which for some reason favours constant westerly winds, though admittedly this is just a guess on my part.

South America is rather narrow at the southern end. That there is not much in the way of terrain features in the area may reduce some of the variation in wind patterns compared to wider continental areas with a variety of terrains over larger expanses? There is also very little land that far south globally. Air can pretty much just keep circling the globe without hitting much of anything until it reaches the Andes.

Hey all

After further tinkering with my world to be, I once again request your criticism of my mapped currents.
I am most unsure about the ocean between the southern continents and the north-eastern coast of the north-eastern continent.
Thank you in advance.

Picturing things like that makes a lot of sense and actually helps clarify some other questions I had. Thanks!

Why does Asia not get rains from the extratropical storm path? Or Africa and Australia, for that matter?

Erm, they do get rains? It's just that for some reason the guide puts the Australian extratropical cyclone rains under the westerlies, and the Asian and African ones under "winter monsoon" (and partially under the westerlies as well).

So, I went through the guide and did the initial precipitation map for January. However I'm unsure about some of the instructions with the transition map, as well as how far I should have certain zones go inland, so I haven't done any orographic lift effects or added in the penalty areas yet; would someone kindly be able to let me know if I'm roughly in the right direction? Much appreciated.

My apologies for doubleposting, but I think I might've run into an error with the new script; whenever I try to run it, it gives me the following error message:

"Plug-in 'Climate Generator' left image undo in inconsistent state, closing open undo groups."

Running it in the python console only gives the following error:
Traceback (most recent call last):
File "<input>", line 1, in <module>
RuntimeError: execution error

Is there any way to figure out what line of code the script crashed on?

I've tried reinstalling GIMP and installing Python, but to no avail. I have, however, been able to successfully run an older version of the script that's on post 334 of the thread. It can be seen as follows, with an added legend:

Going off of intuition, it seems odd that the tundra would go so far south on the coast right continent's top "finger". I'm also guessing that any internal tundra zones are due to mountains.

The forum seems to have eaten the attachment (Attachment 125632) from your previous post, as it is not visible. Just to clarify, which version of GIMP are you running, and which version of the script you have an error with, the one posted in post #555?

[Coggleton]

I replaced the attachment with a text description of the error.

My GIMP version is 2.10.22, and it's the script in post #555 that I'm having issues with.

Can you post your source maps, so I can try to reproduce the error?
