Description :
Recent research for the Swedish Road Weather Information System (VVIS) is discussed along with a method for determining temperature variations attributable to topography during different weather situations. Topographical areas are classified according to factors determining temperature differences. The investigation concentrates on areas where great temperature differences occur during different weather situations, producing a risk of local road slipperiness. Geographical factors analyzed and discussed include valleys, height difference, shadow areas, bridges, and regional climate. The different factors are integrated into a local climatological model.
