Earth with 0 obliquity and 4-hour days (Patreon)

Thought I'd run this quickly between a couple other models just as a fun aside; it was not quick. Exoplasim really doesn't like running with such fast rotation. Even this result isn't fully to balance, but it's about 60 years in so it's probably not far off.

Anyway, I was just curious how steep of a temperature gradient I could get by combining these factors, and as it turns out...steep. The temperate band here is something like 500 km wide along much of its length. This is just the regular climate zone logic (which I have my system set up to make automatically), not seasonless, but that only seems to make a difference at a couple points.

I've had a few commissions by people for various particular combinations of parameters like this that they've said I was free to share with people, so I might wrap them all up in a mini-exploration at some point, but at the moment I'm focused on trying to finally hammer out my final terrain map; I've actually found a decent large-scale glacier model to use in the process, so you can expect a tutorial for that at some point. For climate models, I'll be going back to combinations of obliquity and eccentricity, though for the 90-degree obliquity ones I'm trying a new approach to automatically find the warmest stable ice belt climate and I'm still working out some of the kinks.
