Reviewing long-term temperature, precipitation, and humidity trends across twelve months
Annual atmospheric patterns for Allegheny National Forest are defined by these twelve-month climate normals based on 1991 to 2020 NASA POWER data. These values represent long-term averages at a single representative coordinate, providing insight into monthly mean temperatures, daily precipitation rates, wind speeds, and daylight hours. Observe how these environmental metrics shift systematically from winter through summer at this specific elevation point.
