Weather's Influence. The process of tree leaves changing color in the autumn, prior to falling, is temperature-dependent. As the temperatures fall, chlorophyll -- the green pigment in the leaves -- breaks down, revealing other pigments present in the leaves. The display depends on the weather as well.
The Science of Color in Autumn Leaves. As the days get cooler and frost is in the air, deciduous trees and shrubs put on an autumn show in all shades of red, yellow, purple, and brown. The splendor of crisp fall days and vibrant leaves brings to mind memories for nearly everyone who lives in an area where deciduous forests are the dominant vegetation. In many parts of the country, autumn leaves are an important factor in tourism. Many think that cool weather or frost cause the leaves to change color. While temperature may dictate the color and its intensity, it is only one of many environmental factors that play a part in painting deciduous woodlands in glorious fall colors.
