Exploring the Science of Wind

Wind varies from gentle breezes to powerful hurricanes, caused by air moving from high to low pressure areas. Factors like the sun and Earth's rotation influence wind patterns. Air composition affects pressure, with warmer, moist air rising and creating low pressure, often leading to bad weather. High pressure brings clear skies. The sun's energy and Earth's spin contribute to wind, with the Coriolis effect altering wind direction. Extreme wind speeds have been recorded, such as on Mount Washington and during Cyclone Olivia. The video concludes with viewer engagement prompts.
