【摘要】 选取2004年8月27~29日发生在辽宁的一次区域性暴雨过程个例,应用常规天气图资料并结合多普勒雷达回波资料进行诊断分析,确立了辽宁区域性暴雨模式,并揭示了多普勒雷达的基本反射率、基本径向速度等产品在短时强对流性天气预报中的指导意义。更多还原

【Abstract】 Based on the observation data of regional heavy rain process in Liaoning province from August 27 to August 29,2004 and Doppler radar echo data as well as the conventional synoptic chart data,the applicability of Doppler radar echo in diagnosing heavy rain process was analyzed.A regional heavy rain model for Liaoning province based on Doppler radar echo was developed,and the indicative functions of the products from Doppler radar such as radar reflectivity,radial velocity,were expounded in forecasting short-time convective weather.更多还原
