• In our previous report (O. Saka, Adv. Polar Upper Atmos. Res., 19, 80, 2005), the steady-state flow characteristics in converging field line geometry has been examined by incorporating double adiabatic equations of state. In this report, we extend our previous analysis to examine how the penetration depth of plasma flow varies with a Mach number of the flow. The results obtained here suggest that the penetration depth became deeper than that of the mirror height of the single particle motion in all range of pressure anisotropy when a Mach number increased above 3.0. For a lower flow velocity, however, the flow could not penetrate below the mirror height of the single particle motion.
