Indexes Analysis Method for Ice-Run and Freeze-Up Forecasting in Inner Mongolia Reach of the Yellow River
Taking the cumulative negative air temperature from ice runs presence to freeze-up as the key index factor for the prediction of freeze-up in Inner Mongolia reach,the cumulative negative temperature index required for the formation of freeze-up under different dynamic,thermal and river channel conditions was clarified,and a prediction model for freeze-up index was established.The index analysis method for freeze-up forecasting could greatly improve the accuracy and the forecasting period of freeze-up forecasting.
