Classification by Height
Clouds form at three main atmospheric levels. Low-level clouds (0-6,500 feet) include stratus and cumulus, often appearing dark and dense. Mid-level clouds (6,500-23,000 feet) like altocumulus and altostratus appear as gray or white sheets. High-level clouds (above 23,000 feet) such as cirrus consist mainly of ice crystals, appearing thin and wispy.
Formation Mechanics
Cloud formation occurs when water vapor condenses around tiny particles in rising air. As warm air rises, it cools and reaches its dew point, where water vapor transforms into visible water droplets or ice crystals. Different atmospheric conditions create distinct cloud types. Temperature, humidity, atmospheric stability, and available condensation nuclei influence cloud development.
Weather Indication
Cloud types help predict weather conditions. Cumulus clouds often indicate fair weather, while cumulonimbus signals potential storms. Stratus clouds typically bring steady precipitation. High cirrus clouds may indicate approaching weather systems. Understanding cloud formations aids weather forecasting and aviation planning.Shutdown123
