(a), (b) Parameters of solution defined by Eqs. ( 20 )–( 25 ) shown along propagation direction; (c) self-similar propagation dynamics of the vortex with loss g 0 = −0.01 for the fluctuation of the fiber parameter. The initial values are given by Eq. ( 12 ) with an added 5% white noise. Other parameters are the same as Fig.  1 .
