Based on the 1 shitty course in applied mathematics I nearly flunked, I imagine the velocity of wind is a solution to some kind of differential equation induced by the temperature, and since the sun’s heat is moderately spread around (like you don’t get a hyper-heated cmxcm square or something) these solutions are continuous, so that with ‘one step to the right’ you can feel slightly less wind, but not a huge difference. Maybe five thousand of these can take you from strong wind to no wind at all.
