Surface plots showing time histories of electrostatic potential , charge density , and ion density from the six baseline simulation runs with suprathermal electron parameters specified in Table I. The runs are designated by the letters ordered (top to bottom) from most laminar to most turbulent. The spatial region spanned in these figures corresponds to the central 25% of the entire simulation domain.
Electrostatic potential and synthesized earthward and antiearthward energy-flux spectrograms from simulations runs , , and . The spectrograms are generated for the altitude indicated by the dashed white lines. The dashed black curve in the leftmost potential plot indicates the (approximate) location where the standoff region ends and the hole turbulence begins. Note that the potential plots are flattened versions of the corresponding frames in Fig. 1. Energy and flux units are discussed in the text.
Parameters of baseline set of simulation runs. The runs are designated by the letters and correspond to the rows in Fig. 1, which are ordered qualitatively from most laminar to most turbulent. All of these runs used a suprathermal asymmetry parameter .
