Clouds are formed in Earth's atmosphere when water evaporates into vapor from oceans, lakes, ponds, and even streams and rivers; or by evapotranspiration 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. The water vapor attaches itself to condensation nuclei which could be anything from dust to microscopic particles of salt and debris. Once the vapor has been cooled to saturation, the cloud becomes visible. All weather-producing clouds form in the troposphere, the lowest major layer of the atmosphere. However very small amounts of water vapor can be found higher up in the stratosphere and mesosphere and may condense into very thin clouds if the air temperatures are sufficiently cold. One branch of meteorology is focused on the study of nephology or cloud physics.

The study of meteorology is important to a pilot as weather is an issue that affects not only aircraft performance but also flight safety. In this CD we will examine basic met theory enabling you to develop an understanding of the principles involved and how weather can affect your flying activities. A sound knowledge of the theories behind meteorology will help you, as a pilot, to make good decisions based on the forecasts and reports available.
