摘要
介绍了美国天气预报技术的发展现状。指出在大气探测技术、数值预报及可视化技术发展的推动下美国传统的天气预报向定量与定时方向发展。定量降水预报的实现是天气预报由定性走向定量的重要标志。在充分利用数值模式产品的基础上综合应用卫星与雷达资料建立客观预报工具在暴雨和强对流天气预报中取得较好效果；中尺度分析业务系统的不断改进使降水预报的技巧有明显提高。作者还介绍了美国数值预报产品释用及预报业务系统的概况。最后提出了对我国天气预报技术发展的启示。
The current development of weather forecast technigue in the United States was presented. It is suggested that it is the technological development of the atmospheric probing,the numerical weather forecast and the visualization that impels the conventional weather forecast in the United States toward quantization and timing. The realization of quantitative precipitation forecast is an important mark of qualitative toward the quantitative weather forecast. On the basis of making the best use of the numerical model products, composing satellite and radar data, the method of the objective forecast is established. It makes a good effect on the forecasts of heavy rain and severe convective weather. The advancing of mesoanalysis of operational forecast system improves obviously the forecasting skill of precipitation. The interpretation of numerical weather forecast product and the operational forecast system in the United States are presented. Finally, the inspirations drawn for China's weather forecasts have been put forward.
