Hello guys, sorry for not answering, but I had some troubles.

So, if you both agree that the boundaries between one climate and another aren't well defined, I'll take the Charerg's Koppen Map as the final, without any modification.

Now I would like to indicate an approximated maximum and minimum annual temperature, as well as an approximated purcentage of annual rainfall. I'll calculate the average temperature and precipitation of real world cities with one or another climate.

For biomes I will do the same. What do you think? I know that the different wind currents in my world affect the biomes in a different form than the real cities, but just to get an estimate.
Thank you very much!
