And climates: it is very complicated to do something realistic because it requires to consider a lot of variables at the same time.
Pixie's model is flawed in some places. The biggest problem is probably the approximation factor. Each steps error stacks with the others. And I find that the resulting climates of Palamb are not that realistic.
While Pixie's method is not without merit, (I admit that his maps look really professional) I would rather use it as an indicator rather than a definitive climate map.
If the planet is similar to Earth, I would recommend to use a simplified and standardized classification of the climates that uses precise criteria. Some are based of temperature, altitude, latitude (ex: cold desert are too cold to form between the tropics), precipitation, and geographic location (east vs west). Yes, some climates are almost exclusively found either on the east or west coasts.
You can have a look here at my answer on Worldbuilding SE:

The first part is a general explanation on the climate. The forth part is actually about the different climates and how to place them.
I tried to include all the main factors and to be as concise as possible.
I'm not 100% sure but I think tweaked some numbers about the temperatures here and there to be sure climates would not overlap. The original classification is a bit more complex : the difference between Cwb and Cwc is the number of months with a temperature below 10. (3 vs 4 or more). They still overlap but that is why they need to be painted on the map instead of just generating them with a automatic method.
