摘要： 利用1949—2010年热带气旋年鉴资料和常规气象观测资料，对62a来登陆辽宁热带气旋的生成源地、移动路径、登陆地点、登陆强度、登陆后影响时间等进行统计分析，揭示登陆辽宁热带气旋活动特征。结果表明：1949—2010年共有18个热带气旋登陆影响辽宁，66℅以热带低压（TD）的强度登陆，61℅在08—20时之间登陆，78℅在辽宁境内活动时间为6—12h，89℅是在其他地区登陆进入黄渤海后在辽宁再次登陆，大连是登陆次数最多的地区，33℅登陆辽宁后减弱消失，登陆后移动路径主要有向东北向、偏北向、西北向3种移动路径。在此基础上，根据业务需求建立了基于副热带高压、气旋源地和热带气旋前期路径等因子，预报登陆辽宁热带气旋后期走向[0]的预报关键区，为热带气旋预报工作提供参考。

Abstract: Based on the data from Tropical Cyclone Annual and the conventionally meteorological data from 1949 to 2010, source region, moving path, landing sites and strength of the Tropical Cyclone (TC), the impact time after landing in Liaoning province were analyzed. The results indicate that there are 18 tropical cyclones landing in Liaoning province in recent 62 years. 66% of them lands with tropical depression (TD); 61% of them lands between 08:00 to 20:00 o’clock; 78% of the landing TC last about 6-12 hours in Liaoning province; 89% of them made landfall at other places and moved into the Yellow Sea or Bohai Sea before making landfall again in Liaoning province, mostly landing in Dalian; 33% of them weakens and disappears after landing in Liaoning province. The moving paths of TCs are mainly northeastward, northward and northwestward after landing. Based on these analysis and operational needs, the key areas of forecasting are established in terms of the subtropical high, source region and path of tropical cyclones and so on, which could provide the reference for forecasting of tropical cyclones landfall in Liaoning province in future.
