摘　　要：该文讨论了大连、青岛、上海、福州、厦门和广州６个沿海城市的气块长距离后向输送轨迹。输送层假设在１５００ｍ上。计算了１９８５年１、４、７、１０月份的轨迹。轨迹分析得出：①气块后向轨迹与天气形势和季节有关，且南北方有差异；②北方沿海城市的７２小时气块后向轨迹输送距离要比南方沿海城市远些。Air parcel backward trajectories of long-range transport at six coastal cities, Dalian, Qingdao,Shanghai, Fuzhou,Xiamen and Guangzhou,are discussed.The transport layer is assumed to be 1500 m high, the trajectories during January, April, July and October 1985,are computed. The trajectory analysis shows that: (1 )The backward trajectories of air parcel are related to weather situations and seasons,and however the backward trajectories between the coastal cities in the North and in the South are different.(2)The transport-distances (the backward trajectory of 72 h) of the coastal cities in the North are farther than that in the South.
