摘　　要：利用国家级的气象预报产品质量客观检验评价系统,对辽宁中尺度模式预报MM5和T213数值预报的结果分别进行检验分析。检验类型分为历史资料检验和实时资料检验,检验要素包括地面降水、气温和高空500 hPa环流。检验结果显示,对于降水、气温的预报MM5模式预报检验结果优于T213数值预报,而对于500 hPa环流的检验结果T213更可信。Using the weather forecasting product evaluation system, the results of MM5 and T213 numerical prediction are verified and analyzed, respectively. The verification is conducted based on historical and current data, with verified elements including precipitation, temperature, and circulation patterns at 500 hPa. The results show that MM5 is better than T213 in precipitation and temperature prediction, but T213 is more trustworthy in circulation pattern prediction.
