摘　　要：回顾了近 5年欧美等国实施的 4次外场试验 ,这些试验大都针对灾害性天气 ,例如暴雨、洪水和强风等的预报问题而设计。外场试验期间 ,建立了“目标观测”的概念并在试验中进行了实际应用。来自不同观测平台具有高时间和空间分辨率的传感器给出了大量大气运动实况的详细记录 ,对其中包含的 ,或许我们目前还不能完全理解的大气运动规律的认识 ,是改进预报的重要途径。这些外场试验所收集的所有资料 ,几乎都可通过 Internet得到。Four field programmes conducted in recent 5 years were reviewed.These field experiments were selected since they were designed to address the prediction problems of severe weather systems,such as torrential rain/flooding and strong winds. The concept of targeted or adaptive observation was established and tested operationally during the field experiments. The important improvement could be expected in the disaster weather prediction as the results of these field experiment, during which advanced sensors from different platforms with high spatial and temporal resolution recorded a lot of details of the truths in atmospheric movements that may not be properly understood yet. And even more, almost all these details collected in these field programmes could be shared through Internet.
