摘要
本文进一步对旋转正压大气中的包络Rossby孤立波进行了研究,结果发现当Rossby波的波数m(m为纬向波数)满足1<m<2时,旋转正压大气中才存在包络Rossby孤立波,并且只有m=2的包络Rossby孤立波才具有阻塞高压的结构。我们还对这种m=2的包络Rossby孤立波随纬度变化的持续性进行了计算,得到了许多结果。
This paper is the second part of the author's papers, in the present paper, envelope solitary Rossby waves in the rotating barotropic atmosphere were deeply investigated, it is found that when Rossby wavenumber m(m is the zonal wavenumber) satisfies 1<m< 2 the envelope solitary Rossby waves exist in the rotating barotropic atmosphere, and only when m=2, the envelope solitary Rossby wave exhibits blocking high structure. Furthermore, the persistent time of envelope solitary Rossby wave with latitude for m=2 is also computed , and some results are obtained.
