A reductive perturbation analysis is carried out to obtain expressions for the local speed, amplitude and width of the soliton. The peak value of the soliton amplitude increases and the soliton width decreases with increasing ion temperature. An equation describing the dependence of the reflected-wave amplitude on ion temperature is obtained. The amplitude of the reflected wave is observed to decrease with increasing ion temperature on account of Landau damping.
