摘　　要：利用日本东京JMH台发布的地面24 h、48 h预报图,对温带气旋预报准确率进行了统计分析.结果表明:24 h温带气旋强度预报准确率达到88%,位置预报准确率为84%;48 h温带气旋强度预报准确率为69%,位置预报准确率为71%.对在西北太平洋海域航行的船舶有重要的参考和使用价值.Forecast accurate rate of the extratropical cyclone was analyzed by using the Japanese meteorological facsimile chart. The results show that 24 h forecast accurate rate of the extratropical cyclone on intensity was 88 %, accurate rate on place was 84 %. 48 h forecast accurate rate of the extratropical cyclone on intensity was 69 %, accurate rate on place was 71%. The research results is very valuable for the ships at northwest Pacific Ocean.
