Cloud Types: common cloud classifications Cloud Types
List of cloud types Clouds are formed in the Earth's atmosphere when water evaporates into vapor from oceans, lakes, ponds, and even streams and rivers; and by evaporation or transpiration over moist areas of Earth's land surface. The vapor rises up into colder areas of the atmosphere due to convective, orographic, or frontal lifting. This subjects the rising air to a process called adiabatic cooling. The water vapor attaches itself to condensation nuclei which can be anything from dust to microscopic particles of salt and debris.
