摘要
2004年8月12日,"云娜"台风在浙江温岭登陆,在周围地区造成暴雨大风天气。将客观分离方法(Objective Synoptic Analysis Technique:OSAT)及其改进方案分离得到的台风降水与主观分析得到的台风降水资料进行对比分析。总的来说,两者的分离效果大体一致。对于识别较远距离的台风降水,客观方法比主观方法更加客观、合理,体现出较强的识别能力。此外,还对OSAT中的参数进行调试,对比不同的分离效果。
The heavy rainfall and storm occurring in Wenling City and vicinity in Zhejiang Province on August 12,2004 was caused by typhoon'Rananin'.The precipitation partitioned by the Objective Synoptic Analysis Technique(OSAT) and its improvement programs were compared with that partitioned by subjective analysis technique.Generally,they were consistent.The OSTA was more objective and reasonable than subjective analysis technique in distinguishing long-distance precipitation from tropical cyclones(TCs).Besides,we tuned the parameters in the OSAT and compared the different results.
