Fog and low stratus phenomena can occur at many different places on the globe and at different times of year and day. It's a difficult measure not only to forecast but also to monitor and can have a determining influence on our daily life. During this fog simulator you will have to advise the pilot of a small airplane during his flight across the Alps. It is however not specifically developed for aviation meteorologists. It is made for anyone who wants to practice a common fog situation with basic data (forecast and nowcast), a meteorological background is helpful but not mandatory. The forecast area is Austria but the simulator can be used by all kind of nationalities.
