本文计算了分数阶耗散下准地转方程和Boussinesq模式的IVP解的时间衰减率。此外，我们明确确定的渐近配置文件，内核的稳定过程，这是类似的Oseen涡。
We compute the sharp time decay rates of the solutions of the IVP for quasi-geostrophic equation and the Boussinesq model, subject to fractional dissipation. Moreover, we explicitly identify the asymptotic profiles, the kernel of thestable processes, which are analogues of the Oseen vortices.
