It wouldn't be such a bad thing if the steppes extended further north in Canada, since I think that is the case in real world Köppen maps. I think the error comes because we only use data from extreme months: the continental climates tend to have too low Tann values because of this.Originally Posted by Azélor
Maybe a little more arid yea.
I don't think using the extreme month has a big impact. The temperature follow a bell curve. Temperatures changes more quickly in spring and fall but more slowly in summer and winter. Overall, I don't think the yearly average would be very different.

I'd say there definitely is some difference, because if there wasn't we should be able to sort out the Db/Dc boundary. It would be interesting to compile an "annual mean temperature" map using the categories we use and compare it with an actual map of annual mean temps.
The Updated 6-step Script
Ok, I've now updated the script.
Here's the output:
Note:
I made the slight modification of including the [200+ / 100-50] precipitation combo with Af instead of Am, since that was the case in the prior version as well (and overall the combo is closer to Af prec pattern, I think).
Overall it does match real-world Köppen maps better than the previous version: Australia is more arid, and the cold steppes extend further north in North America and Central Asia. The updated script is in the attachments, as usual.
Installation:
Overwrite the older version of the script if you're using it. Otherwise, follow the instructions in this post.

Yes I think this is an improvement from the previous version.
Next?

Trying to figure out a simple way to map precipitations (July).
So ideally, each colour represent if an area is wet or dry and the reason why. Sometimes a darker colour is used to represent a wet yet drier area.
I'm not sure where this is going.

I guess we could work on adding the 10-13 °C temp category. That should eliminate the awkward Cc-Db transitions that are very common right now and largely sort out the Cc distribution. I feel after that we could consider the main tutorial largely finished, unless you want to develop the 8-step precipitation version further?
Although I guess the development focus could be shifted towards refining the instructions, since I think we're in a pretty good spot with the climate generation even with just the 6 precipitation levels, now that the aridity thresholds have been sorted out (that really did fix a lot of the most problematic regions like Australia).

Maybe.
No, we don't really need 8 categories.
Improving the instructions for the precipitations is a good idea.Although I guess the development focus could be shifted towards refining the instructions, since I think we're in a pretty good spot with the climate generation even with just the 6 precipitation levels, now that the aridity thresholds have been sorted out (that really did fix a lot of the most problematic regions like Australia).

I think it's definitely worth pursuing that improvement, since the Cc distribution is the biggest flaw with the climate generation. Here's the 10x10 temp table where I've highlighted the "bad transition" from Cc to Db:
And the 11x11 table, where the transition is now from Cc to Dc (as it should be):
How do you put it on the map?
Select about 30% of the area?
