The Effect of Meteorological Parameters on Rime Formation in Finland,
Abstract
It can be stated that of the routinely observed meteorological parameters only wind speed seems to be useful in predicting the intensity of rime formation. Air temperature, however, can be used in determining the conditions where glaze is formed instead of rime. The mean wind speed multiplied by the duration of in-cloud conditions seems to be the best available predictor of the ice load. This parameter should be useful in estimating ice loads on power lines, masts, trees etc., using, say, climatological data. The accuracy of this method is, however, limited by the large variations in the liquid water content of air and droplet size distribution. Estimation methods of these factors should be developed in order to improve the reliability of ice load calculations.
