Propagation of Alfvén waves in the magnetotail during substorms
Recent observations from the THEMIS mission have focused attention on the timing of events in the magnetotail during magnetospheric substorms and other periods of geomagnetic activity. Standard models of substorms have generally emphasized convective flows as the major source of energy and momentum transport; however, Alfvén wave propagation can also be an important transport mechanism. The pro...
متن کاملMESSENGER observations of large dayside flux transfer events: Do they drive Mercurys substorm cycle?
The large-scale dynamic behavior of Mercury’s highly compressedmagnetosphere is predominantly powered by magnetic reconnection, which transfers energy and momentum from the solar wind to the magnetosphere. The contribution of flux transfer events (FTEs) at the daysidemagnetopause to the redistribution of magnetic flux in Mercury’s magnetosphere is assessed with magnetic field data acquired in o...
متن کاملCUTLASS/IMAGE observations of high-latitude convection features during substorms
The CUTLASS Finland HF radar has been operational since February 1995. The radar frequently observes backscatter during the midnight sector from a latitude range 70±75° geographic, latitudes often associated with the polar cap. These intervals of backscatter occur during intervals of substorm activity, predominantly in periods of relatively quiet magnetospheric activity, with Kp during the inte...
متن کاملDistribution and compositional variations of plasma ions in Mercurys space environment: The first three Mercury years of MESSENGER observations
[1] We have analyzed measurements of planetary ions near Mercury made by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Fast Imaging Plasma Spectrometer (FIPS) over the first three Mercury years of orbital observations (25 March 2011 through 31 December 2011). We determined the composition and spatial distributions of the most abundant species in the regions sampl...
متن کاملFast Compressional Alfven Waves in a Tokamak
Enhancement of cyclotron damping is theoretically evaluated based upon the wave E-field polarization which is modified by the two-ion hybrid resonance. The degree of enhancement and its asymmetry about the plasma center is consistent with experimental observations. The enhancement factor is very large at low plasma densities at which most of the past damping strength measurements have been repo...
