Thanks for your time, Azelor. You've pointed out some important stuff, namely, that I am ignoring the interaction between temperature and "wetness" when considering how dry is a climate. I think the desert/steppe/continental "gradient" will have to be a little reviewed.
The point of this whole system, however, is to skip numbers - this is not because of laziness, but because there are so many "educated guesses" and approximations when it comes to a fictional planet-system that the uncertainty of any number is absurd. I mean, what's the point of saying a given place has a mean temperature of 25 şC if the margin for such figure is.. say.. 30%. So, that's the rationale behind a fully graphical method, just to explain myself. Of course, you can throw a guess about what exactly "Very Hot", "Hot" or whatever means. I can agree with your guess without second thoughts.
I also want to make this tutorial easy enough for those without a science background - as much as that is possible - and that is why I am trying to define clear and easy to follow rules. Even to the point where some accuracy is lost. I'm not sure how this balance will work out.
Now, as for your valuable comments.
So, I will probably have to review some of the combinations. Say, if a region is Very Hot/Hot in a season and Low in wetness, that roughly equates to "Dry" - and it would still be desert. Do you agree with this generalization?
Altitude is already factored in as one determines wetness maps and temperature maps, so Cold Steppes should appear naturally when a Hot Steppe region is in altitude (and it does in my tests). As for the numbers, I am aware of those, but as I explained I don't think I can bring formulas to this system (Geoff's Cookbook avoided it too).
As I said, I'll review where some of the combinations fall into, namely between cold steppe and continental (C's and D's) and between hot steppe and mediterranean.
Thanks for these details. I didn't know BWn classification. As for the detail about the BSh, if we don't mention it in "the rules", a piece of hot steppe will be classified as cold steppe, if we mention it, the rule gets more complicated... a choice affecting balance between accuracy and friendliness...
This was definitely a choice I made towards friendliness. Merging Csb and Csc allowed for Cold winters. In my tests this covered highlands close to Mediterranean proper (Csa) more than areas immediately poleward of Csa, but it might be a peculiarity of the continent I used. That's why I will have to try this system in different continents.
I get your point but, the thing is, how would you classify a region with Hot summers (over 22) and Cold winters, with sufficient wetness (that's "moderate" or above in the current rules). However, I see Hot+VeryWet Summers with Cold/LowRain Winters falling a bit awkwardly into Cwb - can you find a better fit?
So, the consequence of this is that all regions with an Extreme Cold temperature should strictly be Taiga or Tundra?
Thanks... fixed! (wish all fixes were these simple
As I said, thank you for the help. There's a few questions in the middle of my replies, did you spot them? As for temperature and rain charts, you can see them in a previous post, I have the four side by side when explaining how to "find climate zones".
