| 摘 要： | 用一个β平面准地转正压模式积分１２个模式日，研究涡旋相互作用问题。初始场上有一个台风涡旋和一对涡旋偶极子，它们的等值线均为光滑、规则的分布。规则分布的涡旋之间的相互作用，可以激发出一个非规则的貌似混乱的涡度分布区域。随着时间的演化，在这个非规则分布的区域，一个相对有序的反气旋环流又逐渐显示出来。

| Abstract: | By using a beta plane barotropic quasigeostrophic vorticity equation,two experiments whose integration times equal to 12 model days are performed to study the interaction between vortices.In the inetial fields,there are a tropical cyclone and a dipole which consists of a cyclonic and a anticyclonic vortex.They all have smooth,regular contours.The interaction between these vortices can creat a seemingly disorder and irregular vorticity distribution region.On the contrary,in the temporal process,in the region,an anticyclonic vortex can also exhibit gradually. |
