Consider a Banks Orbital, a space station three million kilometers in diameter, rotating once per day for 1g artificial gravity, intermediate in size between a Bishop Ring and a Niven Ring: https://www.orionsarm.com/eg-article/4845ef5c4ca7c
I'm trying to figure out what conditions would be like if you were living on such a structure. That is, what the conditions would tend to be like, generated by the physics of the system, in absence of further deliberate modification.
The main factors driving weather on a planet are uneven solar heating by latitude, and Coriolis force. On an orbital, these factors are absent and much weaker respectively.
The accepted answer to this question points out that there will be uneven solar heating between a flat floor and steeply climbing sides: Prevailing winds on a rotating space habitat
And the answer to this question discusses the effect of solar tides: Weather on a mini-ringworld/Banks Orbital
In summary, apparently the solar tide would drive a high-altitude wind to match the apparent motion of the sun.
I'm now wondering about the tidal effect on the ocean. Suppose there is a single connected ocean running the full circumference of the Orbital. My first guess would be by analogy with a planet, a tidal bulge would be created in the directions toward and away from the sun, producing two high tides per day, just like on a planet.
But is that correct? This object is much larger than a planet. Would six hours be enough time for water to slosh a significant fraction of the circumference?
Conversely, if solar tide produces a steady wind following the apparent motion of the Sun – I don't know what mechanism produces that – but if so, would the same mechanism apply to the ocean, and produce a steady current? If not, why not?
