| Summary: | The analysis of fog distribution over Switzerland consists of
two different studies:<br>
The first deals with the spatial determination of fog frequencies
and fog types for the early morning. It was realized by
using the daily observations of 320 stations. This point by
point information was spatially interpolated with the aid ofthe
information (mean fog cover frequency) of 94 typical fog distributions
detected from NOAA satellite data. The derived fog
map of Switzerland includes four different fog zones: ground
fog zone, fog-free intermediary and high fog (stratus) zone,
fog-free slope zone, lower up-slope fog zone.<br>
The result of the second study consists of four maps showing
the fog cover frequency of the important weather types with
fog layers over the Swiss Alpine foreland. They were traced
out by using the above mentioned satellite data. The four
maps indicate clearly that the fog and cold air distribution
during anticyclonic weather situations is strongly determined
by the sub-synoptic pressure and wind field. |
