I hear all the arguments one explains to a flat earther as to why the earth is Spherical and not flat. I am not a meteorologist, but I know enough Meteorology for me to fly safely as a pilot. Getting deeper, doesn't Meteorology rely on a spherical model? If yes, then why? I don't think a flat earth could maintain such an incredible, intricate system on a disc anyways.
I point out only disc because we have people who believe in a flat earth. I've never heard anyone explain to a flat earther why or how important meteorlogy relies on a spherical model for weather to work. I, myself, is interested in the nitty-gritty of the very mechanism that runs our weather which happens to involve the shape of our world.
