经验预报 meaning in English
experimental forecast
Examples
- The main research contents of the physical design include : presenting the domestic and international status of space weather and expanding on the need and the importance about the space weather forecast ; sorting the disastrous space weather and discussing their effects and adapted prediction methods ; analyzing the solar disturbing resources of space weather and the precursor or concomitant phenomena of solar eruption based on the newest observational results ; probing into the radiation principle of solar short - wave ray and presenting the computing methods about solar continuum and line spectrum radiation ; extrapolating physical methods of reconstructing the temperature and the emission measure of coronal plasma ; argumenting the effective observing spectrum for space weather empirical forecast and space weather numerical forecast
物理设计的主要研究内容包括：分析目前国内国际空间天气预报的发展现状及开展空间天气预报的必要性和重要性；分类讨论了灾害性空间天气的种类、影响及目前国际上的预报方法：分析了空间天气太阳扰动源及扰动源爆发的先兆现象或者伴生现象；讨论了太阳短波辐射线谱和连续谱辐射强度的计算方法：推导了利用望远镜多波段的观测结果反演日冕等离子体温度、发射量等参数的物理方法：论证了开展空间天气经验预报和发展数值预报有效的成像谱段。 - 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。
