【摘要】 为使船舶驾驶人员对西北太平洋海域热带气旋的生成和活动规律有所了解,利用2010年中国、日本发布的该海域热带气旋实况资料和气候资料进行统计和分析。分析结果表明2010年该海域热带气旋具有个数少,源地集中,位置偏西;登陆个数少,登陆比例大;登陆时间集中,登陆位置偏南等特点。2010年西北太平洋副热带高压异常强大、西伸脊点异常偏西、脊线位置偏南,赤道太平洋地区的海温、垂直风切变异常的这些因素直接影响着该海域台风的生成及移动路径。结论可为该海域航行的船舶提供预防和避离热带气旋的重要参考依据。更多还原

【Abstract】 In order to enable the navigators to know generation and movement pattern of tropical storm which happened at western north Pacific(WNP) Ocean,Tropical cyclones and climate has been statistically analyzed by making use of the data from China and Japan in 2010.The results show that the number of TC over WNP in 2010 was less than average,the forming locations were more concentrated and further west;The number of landing TC was less than the normal but landing ratio was more than normal;the landing position of TC was further south and landing happened in shorter interval.The characteristics of the subtropical high,including the area,strength,ridge position etc,were abnormal during the active period of TC.And the anomaly distribution of important factors,such as the vertical wind shear,sea surface temperature,affects TC generation and moving path directly.The conclusions of this paper can provide important information for ships to keep away from tropical cyclones.更多还原
