Time evolution of (a) the perturbed magnetic field and (﹩{\beta }_{\parallel }-{\beta }_{\perp }﹩), (b) the best-fitted thermodynamic parameters, ﹩{\gamma }_{\perp }﹩ and ﹩{\gamma }_{\parallel }﹩, and (c)–(f) correlation coefficients and compressibility of density/perpendicular pressure/temperature and magnetic field for the initial parameter values of ﹩{\beta }_{\parallel }=4﹩, ﹩{\beta }_{\perp }=1﹩, and ﹩\theta =20^\circ ﹩. (g) Linear growth rate versus ﹩\theta ﹩ for the initial parameter values of ﹩{\beta }_{\parallel }=4﹩ and ﹩{\beta }_{\perp }=1﹩. (h) Linear growth rate versus (﹩{\beta }_{\parallel }-{\beta }_{\perp }﹩) for the initial parameter values of ﹩{\beta }_{\perp }=1﹩, ﹩{\beta }_{\parallel }=2.6\sim 4﹩, and ﹩\theta =25^\circ ﹩.
