TOWARDS A METHOD FOR ESTIMATING THE RISK OF WET SNOW ICING IN A MOUNTAINOUS REGION

Abstract: By the use of high-resolution numerical modeling, the potential for wet snow icing is mapped in a mountainous region in North-Iceland.

Description
Summary:Abstract: By the use of high-resolution numerical modeling, the potential for wet snow icing is mapped in a mountainous region in North-Iceland. The process of mapping the wet snow icing potential is as follows: a) the relative frequency of wind directions when there is risk of wet snow icing is established from observations, b) winds and precipitation patterns are simulated for typical values of static stability in strong winds from 16 directions, c) the wet snow icing potential is calculated for each wind direction, based on b), d) the mean wet snow icing potential is calculated based on a weighted average from a) and c). Next step in developing the method should be based on a comparison between the calculated wet snow icing potential and icing observations where they are available.
