Abstract:
We will discuss the observational and theoretical parts of interplanetary Alfvén wave properties: 1) their phase steepening, forming Alfvénic turbulence, 2) their dissipation, creating magnetic compressibility and leading to the growth of secondary wave instabilities, and 3) the maintenance of interplanetary helicity. Some new ideas on the source of Alfvén waves will be discussed.
