[WIP] World of Aeion

The ITCZ-rainfall should fall over a sufficiently broad area to cover the equator, that is more-or-less what happens on Earth. Alternatively you could fill in those areas afterwards. The extreme high latitudes should certainly be cold (below 0° C in winter). I guess you could have milder temps if you have unglaciated polar areas (the Canadian arctic islands, as an example), but the elevation of the glaciers alone would push temperatures below 0 °C.

For generating the Köppen climates, all you need is to change your precipitation and temperature maps into a format compatible with one of the scipts available in the tutorial thread, then run the script. I wouldn't recommend manually creating either the biomes or the climates, as its both more practical and more accurate to simply generate them from the temp and precipitation data.

Here's an example for your world using my latest gimp script. I somewhat modified the temp and precipitation maps in the process of making them compatible with the script (btw, I recommend using .png format when posting these kinds of images, that way you don't get blurred pixels like with .jpg).

Note that you often get a number of weird transitions from the script due to the limited amount of data used to generate the climates. There should generally be Aw/As climates surrounding the Af areas (and more Am). Similarly tundra climate (ET) should transition to Cc/Dc -> Cb/Db (the script often produces ET->Db transitions in certain areas). So even these maps require some manual cleanup.

Thanks for the link and suggestions! They were very helpful.

I used your script to generate climate map after I made changes to precipitation maps, mostly adding more rain to the equatorial area.

But how could I get from climates to vegetation? I tried to use mbartelsm method on the maps prepared for your script, but the results were... strange. Especially the prevalence of charpal biome that covered about 1/3 of all lands and spanned over very diverse climates - Cfa, Cfb, Bsh, Bsk, Bwh, Bwk and more. As well as steppe/forest patch on the equator.

I decided to postpone the work on global affairs for now, instead I made a map of the area that interest me the most - The Inner Islands of Elmera - the heartlands of an old Kentran Empire. Now, after 150 years of political struggles and epidemics, the Empire is crumbling. Large areas either broken off or lay waste, while new powers rise. In the north, Most Serene Republic of Zetau is the dominant trade power in the region. In the East, Battomanori dynasty unified Hurkanian tribes and established powerful kingdom. And to the south, raiders from the Torkat Alliance grow more and more secure, crossing the seas in swift xebecks hunting for plunder and people for their bloodthirsty gods.

And preliminary political map with the major factions.
