Snow Accretion Prediction Method Using WRF Calculation Results

North part of Japan is one of the heaviest snowfall regions in winter. In a certain case, wet snow accretes to civil engineering structure such as power lines. There is a demand for the prediction that when the snow accretion will occur. General weather forecast is not enough resolution and meteorological variable for estimating snow accretion. By calculating weather condition on our own account, we can extract related information about snow accretion, and use for prediction. In this study, we consider about the snow accretion prediction method using numerical weather prediction model WRF.
