I thought you said you've looked into flat Earth. The Sun and moon on a flat earth model are the same size, orbiting locally in LEO around the central axis in the North pole. The orbit path expands and contracts with the seasons, wind works the same as the Sun still emits radiation and still disperses that heat unevenly. The circumference of the Earth on a globe model is the circumference of our "Solar spot" on a Flat Earth model which is surrounded by Ice on the fringes of the Localized Suns Orbit and its calculation would be the same based on the position and relative output (reduced distance and size from globe model) of the Sun. Instead of contributing events to "gravity" it is rather attributed to the Aether and the electromagnetic effect that an enclosed system would produce under such circumstances. https://earth.nullschool.net/#current/wind/surface/level/conic_equidistant=294.81,-13.03,131 This tool ten years ago utilized a Flat Earth/ UN style projection, If you wanted to bring up something worthwhile it should have been a lunar eclipse. Which could be a localized phenomena of the moon itself or a result of the Mythical Black sun or Binary companion star nemesis.
