The results show that, the development and evolution of initial perturbation errors have a close relationship with the regions of the convective instability and the horizontal wind fields.

This paper focuses on the perturbation which takes the sine form. The effect of amplitude, frequency, wave number, and initial phase difference on the propagation of optical soliton is investigated.

The singular perturbation of the initial boundary-value problem for a kind weakly coupled reaction-diffusion equation system is discussed.
