The video explores the phenomenon of howling wind, often depicted in stories, and explains how sound is created by air vibrations. It delves into how wind interacts with obstacles like trees and buildings, creating Von Karman vortices that produce audible howling. The presence of leaves can dampen these sounds, while leafless trees allow the howling to travel further. Additionally, wind can howl in open spaces due to pressure differences, contributing to the eerie sounds heard in nature.
