Dispersive Alfvén Waves Observed by Cluster at the Magnetopause

Khotyaintsev, Y.; Stasiewicz, K.; Grzesiak, M.

We have analyzed ELF turbulence ∼0.03 - 10 Hz) observed by Cluster at the magnetopause layer during 120 multiple magnetopause crossings on a single event, December 31, 2000, 09-16 UT. Multiple crossings are produced by nonlinear, large amplitude surface waves at the magnetopause. Waves below the proton gyrofrequency fci ≈ 0.3 Hz) are identified as…
