中文摘要:

      本文利用两层斜压准地转模式,讨论了波-流相互作用问题,得到以下结论:(1)当大气中基本流切变较大时,波流间能量交换明显。切变较小时,波幅变化较小;(2)在较小的基本流切变下,波动可出现稳定的平衡态,此平衡态多为相当正压状态;(3)斜压波在发展过程中,温度场和流场之间具有制约关系。

英文摘要:

      Using a two-lager baro clinic quasi-geostrophic model,a nonlinear system including the interaction between the wave and zonal flowis studied.It is shows:(1)The stronger the vertical shearing flow is.the obvio user the energy between wave and flowis.(2)Under the litter vertical shearing flow,the wave may appearequivalent barotropicity.(3)It has restrict relation between the flow field and temperature field on the process of development.
