Title: Forecasting of winter precipitation phase state in Northeast China based on WRF mesoscale model
Abstract: The forecasting of winter precipitation phase state in the Northeast China was attempted with a mesoscale numerical weather prediction model(WRFV3.1.1).According to the percentage of frozen fraction of precipitation mixing proportion in atmosphere near the ground in water vapor mixing proportion that may condense into precipitation,the rain snow boundary line,sleet area,the transition zone of rain snow were determined.The results indicate that this method could forecast the distribution areas of rain,snow and sleet and the evolution of precipitation phase state during precipitation process with a relatively good accuracy.The application of these numerical forecast products could significantly improve the accuracy of weather forecast.
