How Does Fog Form – Dew Point, Relative Humidity, Types of Fog and Visibility Explained

How does fog form and why does it often appear at night or near water? This detailed evergreen educational video explains the physics of fog formation, including the role of dew point temperature, relative humidity, condensation, and atmospheric stability. Learn how water vapor transitions into microscopic droplets, why condensation nuclei are necessary, and how cooling of air leads to saturation. The video compares radiation fog, advection fog, orographic fog, and evaporation fog, explaining how each type develops under different weather conditions. It also explores why fog reduces visibility, how light scattering works, and how fog dissipates when temperature or humidity changes. Ideal for students, weather enthusiasts, and anyone interested in meteorology and atmospheric science. #fog #howdoesfogform #meteorology #dewpoint #humidity #atmosphericscience #weatherexplained #condensation #climate #evergreen
