Near-Earth plasma sheet boundary dynamics during substorm dipolarization
Strangeway, Robert J.; Plaschke, Ferdinand; Russell, Christopher T. +29 more
We report on the large-scale evolution of dipolarization in the near-Earth plasma sheet during an intense (AL ~ ‑1000 nT) substorm on August 10, 2016, when multiple spacecraft at radial distances between 4 and 15 RE were present in the night-side magnetosphere. This global dipolarization consisted of multiple short-timescale (a couple o…
Spectral moments for the analysis of frequency shift, broadening, and wavevector anisotropy in a turbulent flow
Narita, Y.
Turbulence represents essentially random fluctuations that evolve both spatially and temporally, and appear in various geophysical and space science applications. A spectral moment method is proposed to characterize the turbulence energy spectra in the wavevector and frequency domain in the lowest-order sense. The frequency shift velocity and the …
