Compressive Energy Fluctuations in Solar Wind Turbulence

Study on identifying compressive fluctuations in solar wind's inertial range. Correlation analysis suggests slow waves dominate compressive energy. Lack of fast waves may impact dissipation. Data comparison indicates connection between density and magnetic fluctuations.

  1. Identifying Compressive Fluctuations In Inertial Range Solar Wind K.G. Klein1, G.G. Howes1, S.D. Bale2, C.H.K. Chen2, C.S. Salem2,J.M. TenBarge1 1University of Iowa 2University of California, Berkeley SHINE session: The Dissipation of Solar Wind Turbulence • C(δn, δB||) from ~1.2x105 WIND data intervals is ~-1 • Correlation implies that a preponderance of the compressive energy is due to slow waves • Lack of fast waves may have implications for in dissipation range Correlation of density and parallel magnetic fluctuations: Points from WIND data, Lines from synthetic data model.
