The Appalachian Mountains primarily experience a humid subtropical climate, particularly in the lower elevations. This climate type is characterized by hot, humid summers and mild, wet winters. The southern parts of the range, such as areas in North Carolina, Tennessee, and Georgia, experience this climate more strongly, influenced by warm, moisture-laden air from the Gulf of Mexico. While the higher elevations of the Appalachians may have cooler temperatures and snowfall, the overall climate in the foothills and valleys is typical of a humid subtropical environment, fostering diverse vegetation and wildlife in these regions.
