Upwind → It is formed from "up" (meaning in a higher position or direction) and "wind" (from Old English "wind", meaning air in motion). The word "upwind" refers to the direction from which the wind is blowing, indicating a position relative to the wind's source.
Think of being in a higher position ('up') relative to the direction the 'wind' is coming from — that's what upwind means.
