OK, that makes sense. Are there any changes you'd make to my latest climate diagram, going by your winds and ocean currents?
No, I think you've got it. I think an important topic now that you've got climate is weather. And once you have that, then you need to attend to hydrography (rivers,watersheds, seasonal flows), and finally vegetation, and I suppose fauna. Then you'll have most bases covered to start evolving cultures.
I note that Stewarta is quite hilly everywhere except North Valley and Bight. Your desert and savannah areas seem pretty rugged. Might want to think about some plains in some places. Places that have a lot of water flow in the last 1/2million years or so probably are pretty eroded, with canyons (the sides of which are mountains). Places that have had a lot of water flow for longer periods tend to fill up with silt and become plains, which, when the water source is no longer available, could become desert-like. Think about South America's mountains, very young, very steep, very canyony. The Himalayas and the Alps are also young. Australia is OLD. Canada has been planed smooth by ice ages. The Grand Canyon of the Colorado has eroded itself through the plateau, not by starting as a stream on top, but as a river that cut its canyon, while the plateau around it was being raised. The Colorado River is, in Arizona, about at the same altitude as it was several million years ago; the plateau has risen up as it has delved down, the original delta is likely the Mojave or something.
Blah, blah, I could go on forever. The story of Earth's geology and geography is vast and complex and there are examples of neat things to try everywhere you look.
And the other continents at least need outlines, and probably terrains, mountains and rivers, and climactic things..Then the currents can be completed. Having an entire Earth-sized planet with North America and Australia on it leaves a LOT of ocean; I expect planetary-wide oceans can develop some extreme conditions. The Earth is 2/3 or 3/4 ocean, but it seems like yours is probably 4/5s. Just guessing here. But there is a lot of empty ocean. Cyclones could conceivably traverse the entire globe, depending on ocean temps and other weather; there is little to stand in their way on stewarta-world. (I forget whether you've named the planet).
