A very, very preliminary sketch of Yih. It doesn't really say anything I haven't made known already. Yih has an axial tilt of exactly 30 degrees, and a ring that casts a shadow on the subtropics and mid latitudes in the winter. Yih is slightly larger than Earth, but is a little less dense, giving at surface gravity of 0.88g.

I have to figure out how the ring affects the climate. With two years of meteorology classes under my belt, I have a passing understanding of relevant topics like the three-cell model, the interplay of wind and ocean currents, semi-permanent and seasonal (anti)cyclones, etc. With less insolation in the mid latitudes, I regret to say that Yih likely doesn't have the massive twisters I'd hope for.

Edit:

I might be wrong on that. The decreased insolation only happens in winter. So maybe I can give Yih a tornado alley after all, or as I shall call it, the Suck Zone™.
