I don't get it.
Uh... that's more than a little obvious my friend.
Is that supposed to prove a round-earth? If the programmer put it on a cube would it prove a cube-earth?
We're
not talking about proving a round earth. We're talking about the cause of surface winds, and why they're different north and south of the equator. Have you not heard of the Coriolis effect?
These wind patterns are caused
by the geometry of the earth; the shape of the earth wasn't caused by
the winds LOL. Your powers of logic are a tad shaky I'm afraid; you're transposing cause and effect.
And no; the programmer couldn't have modelled this on a cube—for more than obvious geometrical limitations apparent to anybody vaguely familiar with topology and/or geophysics.
At any rate
Pongo, please feel free to post
your flat earth representation of the wind patterns on your flat earth model. I'd be interested to see how they work in comparison to the established round earth model.
