冰情预报 meaning in English
ice condition forecast
Examples
- Based on the data of ice flood from 1957 to 1983 , the method of topological forecasting of grey theory was applied to study the law of ice condition of inner mongolia reaches of the yellow river , and topological models of ice flood were built , and the freeze - up date and break - up date of the yellow river from 1984 to 2005 were calculated
摘要本文应用灰色拓扑预测方法，根据1957年- 1983年的实测资料，探讨黄河内蒙古段冰情预报的规律，并建立了冰情预测模型，对1984 ~ 2005年的开河、封河情况进行了预测。 - Taking ningxia - inner mongolia reach of yellow river as a study case , a ice regime forecast data warehouse is established for the datamining concerned on the basis of the analysis on the ice regime changing law and its influencing factor of the reach , and then the conceptual mathematic model and artificial neural network model for the parameter calibration of ice regime forecast are built up with gis in combination of the relevant empirical forecast models based on the principles of the hydrological flow muting , thermodynamics and ice hydraulics etc . , with which the design and development of the decision support system for the ice regime forecast with the integrated functions of information inquiry , model parameter calibration , temperature forecast and ice regime forecast are preliminarily discussed
摘要以黄河宁蒙河段为例，在对河段历史冰情变化规律及其影响因素分析的基础上，建立冰情预报数据库，进行数据挖掘，并以地理信息系统( gis )为平台，以水文学流量演算、热力学、冰水力学等原理为基础，结合相关经验预报模型，建立用实测资料进行参数率定的冰情预报概念性数学模型和人工神经网络模型，初步探讨了集信息查询、模型参数率定、气温预报、冰情预报等功能为一体的冰情预报决策支持系统的设计与开发。
