We compute properties of Alfv¿nic fluctuations within a wide frequency range (i.e., 10-6 s-1≲f≲10-2 s-1) in both high- and low-speed magnetized radial solar winds. In particular, the radial and frequency variations of the normalized cross helicity &sgr;c, the Alfv¿n ratio A, and other relevant quantities associated with Alfv¿nic fluctuations are presented and analyzed. Because of the existence of the Alfv¿n critical radius rA and a characteristic frequency fc for a given magnetized solar wind profile, continuous reflection effects are clearly manifest at frequencies lower than several times fc. Since outward propagating fluctuations which many authors consider Alfv¿nic fluctuations have been detected in the high-latitude solar wind (which is fast and steady), such continuous reflection effects in the low-frequency end of the fluctuation spectrum may be found in the Ulysses data. In order to strengthen our case, comparisons are carried out between our theoretical results and previous data analyses of observations from the Helios 1 and 2 spacecraft in the radial range of 0.29 AU≲r≲1.0 AU. Stronger evidence for continuous reflection effects of low-frequency Alfv¿nic fluctuations is found in the high-speed solar wind close to the Sun than in the low-speed solar wind in general.¿ 1997 American Geophysical Union
