摘要/Abstract

摘要： 为了在同一平台查阅不同渠道获得的气象观测资料，并生成中尺度数值模式的初始场，贵州省气象局引进LAPS（局地分析预报系统）并进行初步本地化。对2015年6月贵州省内2次大范围降水过程进行诊断分析。结果表明，融合了多种本地观测资料后，LAPS系统所输出的分析场可以较好地显示因为站点分布不均等原因而不易观测到的中尺度天气系统。但是，在反映基本反射率时，数值偏大，目前仅用于预报员参考其最大值所处的位置，暂时不能用于雷达定量降水估测（简称QPE），还需要进一步的研究和订正。

Abstract: In order to consult meteorological observation data from different sources in the same platform, and supply better initial fields to mesoscale numerical models, the Local Analysis and Prediction System (LAPS) was introduced and localized by Guizhou meteorological bureau. Two large-scale precipitation processes in Guizhou in June 2015 were diagnosed and analyzed. The results indicated that: the LAPS analysis field had more detailed description of mesoscale weather system after being fused with multiple local observation data. But in the output of the basic reflectivity factor, the value was too large, it was only used by forecasters referring to the position of the maximum value at present, and could not be used for the quantitative precipitation estimation (abbreviated QPE), further research and revision were also required.
