The propagation of Alfvén waves in spherically symmetric, isothermal solar wind models with two different temperatures T₀=2.85×10⁶ K and T₀=8.2×10⁵ K is considered. The steady-state Alfvén wave equations are solved numerically and the resulting reflection coefficient and non-WKB effects are calculated. The obtained results show that the reflection coefficient is practically zero in the high-temperature wind model, where wave reflection and non-WKB effects are essentially absent, and that it can also be zero in the low-temperature model, where wave reflection and non-WKB effects are present. A physical explanation of these results is given.
