Weather is the state of the atmosphere, especially the [https://en.wikipedia.org/wiki/Troposphere troposphere], at a given time for a given place. Calculating the complete atmosphere or even a small part of it is extremely demanding in computing power. Hence, FlightGear calculates the state of the atmosphere only for a vertical line beginning at earth's center straight through your aircraft up to an appropriate altitude. For every point along this line, the following fundamental parameters are calculated: | Weather is the state of the atmosphere, especially the [https://en.wikipedia.org/wiki/Troposphere troposphere], at a given time for a given place.
