本文考虑海洋流体动力学中一类约化重力二层半方程组解的适定性，通过构造适当的近似解，利用弱收敛方法，得到了当初始值较大且球对称时，二维外空间区域弱解的整体存在性.
In this paper, we consider the well-posedness of solutions to a reduced gravity two-and-a-half layer system in oceanic fluid dynamics.By constructing suitable approximate solutions and using the method of weak convergence, we obtain the global existence of weak solutions in two-dimensional exterior spatial domain, when the initial data are large and spherically symmetric.
