On a certain planet, the sole continent of land is a large circumspecting ring about the equatorial regions, with a width averaging 500 miles. Rotational north and south are entirely pelagic. Mass is roughly 1.5 times that of the Earth, and atmosphere is of mostly the same as here on Earth. Diurnal period, or rotation about its internal axis, is roughly 36 chronal hours with our SI units. Photosynthesis uses chlorophyll and soils are mostly the same as Earth also. In short, it is like a larger copy of the Earth with a different arrangement of oceans and land.

The planet is tectonically inactive, in that the mantle is unperforated and unbroken, and I suspect that it would be quite stable, barring some cataclysm.

Its sole satellite, which is approximately one-third its mass and at slightly more twice the distance between Earth and Luna, orbit each other with nearly parallel axes.

Their axial tilt with respect to solar plane is approximately 28° arc. The parameters of their solar orbit is almost the same as that of the Earth.

The sun is Main Sequence, and lies somewhere between the G and K spectral classes.

Obviously my numbers are not precise yet.

Anyway, I expect that the large oceans would produce strong wind currents which would shift direction twice during the solar orbit, with the moist air causing seasonal variations of arid and soggy in some places as a result of the rain shadow. Otherwise, however, the climes should be mostly temperate.

What would be the climate equilibrium state, if any?

On a certain planet, the sole continent of land is a large circumspecting ring about the equatorial regions, with a width averaging 500 miles. Rotational north and south are entirely pelagic. Various shallow seas exist on this continental stripe; some of these seas could join the surface layers of the two oceans.
