Weather for Pilots. A work created for anyone who wants to learn all the fundamental theoretical concepts about aeronautical meteorology. From basic knowledge about the atmosphere, to the most advanced knowledge about adverse weather. Everything, absolutely everything a pilot must learn about this fascinating topic The atmosphere, pressure, temperature and dew point, humidity, wind, darkening phenomena such as fog, clouds, storms, the main meteorological factors that affect aviation. All these topics explained in detail and with examples that will make it easy to understand. Predicting meteorological changes in the short term is not impossible, only the necessary tools are required, such as reports, maps and statistics. Here you will find the right way to interpret all this information, to make the right decision when making a flight, or during its development. A complete work, which meets all the requirements to offer, not only to pilots, but to all readers, a generalized knowledge of the climate, its behavior and its possible predictions.

This topical volume of the Journal of Pure and Applied Geophysics utilizes new information not previously accessible for fog related research. It focuses on surface and remote sensing observations of fog, various numerical model applications using new parameterizations, fog climatology, and new statistical methods. The results presented in this special issue come from research efforts in North America and Europe.
