I could swear I knew the answer in grade 5 and no longer remember but like at what point is it one step to the right and no wind and suddenly wind a step further. Like rain starts from the clouds (and I assume thunder too) but what about wind.

    “Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.” source

    There are neither beginnings nor endings to the turning of the Wheel of Time. But it was a beginning. Born below the ever cloud-capped peaks that gave the mountains their name, the wind blew east, out across the Sand Hills, once the shore of a great ocean, before the Breaking of the World.

      I don’t care what anyone says about the show I’m pumped to watch s2e6 tonight.

            I thought season 1 was okay. Weird Perrin had a wife… don’t know how that will play out later. Did they use matches at the beginning? I guess that plot is gone but it was minor enough I guess. Additional romance stuff was typical to gain a broader audience I suppose. Overall I was relatively happy. Much better than Sword of Truth’s show adaptation.

            Didn’t know season 2 had started, is it further from the books?

              They didn’t have matches in the books prior to Mat traveling with the Illuminator who invented the cannons. She also invented the matches.

    To add to others, wind also is generated when a rain “microburst” occurs.This happens frequently in the southwest U.S.

    A microburst is when a very large amount of water is dropped out of the clouds. The gaining rain speed pushes the air below it out of the way. The air is pushed outward horizontal to the ground, which in essence is a massive wall of wind.

    Often in the Sonoron desert a microburst causes the wind to push a lot of dirt from the ground surface to be blown out with the wind. When this happens it’s called a haboob. The wall of thick dust and particles can be up to a mile high and as wide as a city.

    Below is a link to an image of a haboob over Phoenix, Arizona.

    It’s easier to think about it in terms of where is the wind going.

    Air moves into adjacent regions that have lower pressure. It begins everywhere but is moving towards these areas of lower pressure.

    Where does an ocean wave start?

    All currents are circular when you zoom out far enough, and are driven by inequalities in energy. Inequalities in thermal energy, for wind, and wind energy, for waves. Inequalities in voltage drive electrical current, which is remarkable fluid like, in its behavior.

    Terry Pratchett taught me that wind is caused by all of the trees waving about.

    The Coriolis force contributes to large-scale wind movements such as hurricanes.

      I don’t think it’s relevant to the creation of the wind. Just its direction.

    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 have reasonable continuity properties, 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.

    Wind has many sources from a meteorological/climatological standpoint. Breaking wind, however, is a biiiiit more specific.
