Because wind is caused by the gases of the Earth’s atmosphere moving about in an attempt to equalize pressure, it seems natural to assume that wind would blow outward from areas of high pressure, towards areas of lower pressure. In a perfect world, free from other influences, this would indeed be the case. However, sometimes other factors can cause wind to blow differently than this expected pattern.
Three important factors affect the direction that wind blows. These factors are pressure gradient, the coriolis effect, and friction.
