| 摘 要： | 从强迫耗散无辐散正压涡度方程出发，用不同方案模拟试验得到它的数值解，它与方程解析解的特征较为一致，结果表明非绝热加热强迫强“Kelvin”猫眼强度，冷却则相反，耗散则缓和流场演变，模拟所得“猫眼”强度，移动及形状变化及涡度场等特征与副高实际演变有相似之处。

| Abstract: | Using the forced dissipative nondivergent nonlinear barotropic vorticity equation and by means of various schemes,we get its numerical solution,which accords with the attribute of its analytical solution.The results show that diabtic heating strengthens Kelvin cat's eyes,and cooling weakens cat's eyes.The dissipative effect slows down the evolution of stream function field.The strength,movement,shape and vorticity field attribute of simulated cat's eyes possesses some similarity to the evolution of actual subtropical high. |
