CISK影响下的线性和非线性惯性重力波

THE LINEAR AND NONLINEAR INERTIAL-GRAVITATIONAL WAVES INFLUENCED BY CISK

利用板对称的大气动力学方程组，考虑线性和非线性两种ＣＩＳＫ加热过程，由行波法和非线性常微分方程定性理论，讨论了ＣＩＳＫ影响下的线性和非线性惯性重力波的稳定性，以及ＣＩＳＫ对惯性重力孤波强度和宽度的影响．结果指出，线性ＣＩＳＫ既影响孤立波的强度，又影响孤立波的宽度，而非线性ＣＩＳＫ只影响孤立波的强度．

By using the equations of atmospheric dynamics with polar symmetry, the linear and nonlinear CISK heating processes are investigated. Using travelling wave method and theory of qualitative analysis of ordinary differential equation, the stability of the linear and nonlinear inertial-gravitational waves with CISK process and the influence of CISK process on the intensity and width of soliton of inertial-gravitational waves are discussed. The results show that linear CISK process affects not only the intensity of soliton, but also the width of the soliton, while nonlinear CISK process only affects intensity of the soliton.
