This document discusses various types of clouds and precipitation. It describes cloud formation processes like orographic lifting, fronts, convergence, and localized lifting. It explains cloud types like cirrus, cumulus, and stratus clouds. The document also covers precipitation formation theories like Bergeron process and collision coalescence. Finally, it defines different types of precipitation including rain, snow, sleet, glaze, and hail.

Cloud types and Precipitation
• Cirrus- high up, white, and are thin.
Look like wispy feathery cloudy
• Cumulus- big fluffy clouds that have a
flat bottom
• Stratus- cover much and often most of
the sky. No distinctive individual clouds
13. High Clouds
• Bases reside between 16000 and 45000
feet
• Because of the altitude they are
mainly composed of ice crystals
• Clouds in the region would be cirrus,
cirrocumulus, and cirrostratus
14. Middle Clouds
• Bases found at 6,500 to 23,000 feet
• Main clouds here are altostratus, alto
nimbus, and nimbostratus clouds
• Their height depends on the region
they form
16. Rain and Snow
• Forms when water droplets in clouds
size up one million times
• Depending on the weather in the
region, the water droplets may freeze
into crystals and become snow
