How much influence did the atmosphere and wind have on bows and arrows in ancient times?

That's great. To understand the influence of wind on shooting objects, whether bullets or bows and arrows, we must understand the meaning of muzzle velocity. The greater the initial velocity, the smaller the influence. Of course, the initial velocity of bows and arrows is not as good as that of bullets, and the wind speed of snipers during World War II can not be underestimated, not to mention ancient bows and arrows. At the same time, although bows and arrows are generally streamlined, they are large in size and have a much larger stress area than bullets. Unless it is a super crossbow, the influence of wind must be considered.
