| Abstract: | 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. |
