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.
