| 摘 要： | 利用ECMWF15天平均资料计算了定常波的EP通量以及波动动能和有效位能的三维分布。发现了大气中某些新的遥相关型,特别是从中纬度传播到热带地区的波列在那里发生路径转向和透射的现象。指出对流层低层向上传播的有效位能可能对维持高空定常波有一定作用。同时讨论了大气中的三维遥相关特征。

| Abstract: | To investigate three-uimensional propagations of planetary waves in the atmosphere, 15-day averaged ECMWF Climate Data was used to calculate threedimensional F-Flux and distributions of kinetic energy and avilable potential energy. Some new teleconnection patterns of the planetary wave propagations were discovered, especially the reute turnings and transmissions of eqatorward propagating Rossby waves in the tropics. It is pointed out thet upward propagations of avilable potential energy from the lower troposphere seem to make some contributions to the maintainences of the upper troposphere and stratosphere stationary waves. Meanwhilc, three-dimensional teleconnection patterns in the atmosphere were discussed. |
