摘要
文章利用ERA Interim的0.25°×0.25°再分析资料和常规探空资料,对2013年7月21日内蒙古巴彦淖尔市一次强降雹过程进行物理量诊断分析,考察了再分析资料在此次冰雹天气过程分析中的适用性。结果表明,高分辨率的再分析资料能够较为合理的给出此次冰雹过程发生的不稳定条件、水汽条件、动力条件等环境特征。而实况探空资料由于不满足"临(邻)近"原则,并没有反映出冰雹发生的环境条件。因此,在业务及科研工作中,可以利用ERA Interim再分析资料对某些强对流天气进行诊断分析。
In order to investigate the applicability of reanalysis data in the analysis of hall weather process ,the physical quantity of a strong hail process in Bayannu in 2013 was investigated by the ERA Interim data and the radiosonde data. The results showed that： The high resolution reanalysis data can give a reasonable analysis of the environmental characteristics, such as the unstable condition, water vapor condition, dynamic condition and so on. The radiosonde data does not reflect the environmental conditions of hail. Therefore, in the business and research work, we can use the ERA Interim data for the diagnosis and analysis of some strong convective weather.
