Compressive fluctuations in high-latitude solar wind

Bavassano, B.; Pietropaolo, E.; Bruno, R.

. Solar wind compressive fluctuations at MHD scales have been extensively studied in the past using data from spacecraft on the ecliptic plane. In the present study, based on plasma and magnetic field measurements by Ulysses, a statistical analysis of the compressive fluctuations observed in the high-latitude solar wind is performed. Data are from…

Solar wind velocity at solar maximum: A search for latitudinal effects

Bavassano, B.; Bruno, R.; D'Amicis, R.

Observations by Ulysses during its second out-of-ecliptic orbit have shown that near the solar activity maximum the solar wind appears as a highly variable flow at all heliolatitudes. In the present study Ulysses data from polar latitudes are compared to contemporary ACE data in the ecliptic plane to search for the presence of latitudinal effects …
