Microscopic particles in the atmosphere that enable the formation of cloud droplets Cloud condensation nuclei (CCN) are tiny airborne particles in the atmosphere that serve as surfaces on which water vapor condenses to form cloud droplets. Without these microscopic particles, the formation of clouds in Earth’s atmosphere would be extremely inefficient because pure water vapor […]

Humidity is the concentration of water vapor in the air. It is a fundamental concept in meteorology, climatology, and environmental science, influencing weather, human comfort, and ecological processes. Humidity is typically expressed as absolute, relative, or specific humidity, depending on the measurement and application. 🔬 Types of Humidity 🌡️ Absolute Humidity Absolute humidity measures the
Fog is a meteorological phenomenon consisting of suspended water droplets or ice crystals near the Earth’s surface that reduce horizontal visibility to less than 1 kilometer (0.62 miles). It is, in physical terms, a cloud in contact with the ground. Fog forms when air becomes saturated—meaning it holds as much water vapor as it can
