| 摘 要： | 全国多普勒雷达网的建立，使我国气象观测网的监测手段和监测能力大步提高，对监视强对流天气和强降水天气以及短时临近天气预报起到了不可替代的作用，而如何将这一先进技术应用到地面气象观测中，目前还很少有人尝试。作者在地面气象观测中就多普勒雷达反射率因子图对积雨云和雷暴等对流天气的监视作用作了一些大胆的探索。应用雷达反射率因子图上各种信息，结合云天实况指导对“积雨云”和“雷暴”系统的观测，帮助更及时、准确地判定其生成、方位、强度、范围、距离等。

| Abstract: | It improves the monitoring capability and means that the National Doppler radar network was established. It plays an irreplaceable role in monitoring severe convective weather and rainstorm as well as short-term weather forecasting. There is few application of this advanced technology in surface meteorological observation. The monitoring of the cumulonimbus and thunderstorms by Doppler radar reflectivity factor graph in surface meteorological observation was explored. Based on the information from the graph of Doppler radar reflectivity factor and combined with the surface meteorological observation, the generation, position, strength, range of the cumulonimbus and thunderstorms are determined more timely and accurately. |
