Why Is Snow White?
from The Curious World
The episode explain the fascinating optical science behind snow's white appearance and examine the complexities of measuring historic winter weather events. Although individual ice crystals are clear and translucent, they scatter and reflect light in various directions so that all visible light frequencies are combined and reflected back as white. When evaluating massive winter storms, determining the greatest snowstorm depends entirely on whether analysts measure fresh snowfall accumulation, existing snowpack depth, geographic scale, or human impact. Furthermore, geographical factors like orographic lift in mountain ranges and lake-effect conditions heavily influence regional precipitation patterns. Ultimately, evaluating weather extremes requires looking closely at standardized measuring intervals, observation locations, and the specific hazards that transform a standard blizzard into a historic disaster.
