What phenomenon is responsible for cooler temperatures during the fall in Mississippi?

The phenomenon responsible for cooler temperatures during the fall in Mississippi is the decrease in sunlight and angle of the sun. As fall progresses, the Earth’s tilt relative to the sun causes the sunlight to hit the surface at a lower angle. This results in shorter days and less direct sunlight, which leads to a reduction in overall temperatures. The combination of these factors is significant in transitioning from the warmer temperatures experienced during the summer months to the cooler conditions typical of fall.

As autumn advances, not only does the intensity of sunlight decrease, but the overall energy received by the Earth diminishes, contributing to the gradual cooling of the atmosphere. Understanding this principle is essential when studying seasonal climate variations, particularly in regions like Mississippi, which experience distinctly warm summers and cooler falls.
