Weather patterns look much more sensible on a Flat Earth map, such as in this photo.
Rather than swirling around randomly, as it does on the Globe model, the symmetry of wind and weather appears to be exactly correlated to its location on the flat AE map.
As for the cause, I would say that the Bible gives us that answer: God, who made the heaven and the earth --
"He scattereth his bright cloud: And it is turned round about by his counsels."
