| Abstract | Polar Cap Boundary Layer waves are ELF/VLF electric and magnetic waves detected on field lines adjacent to the polar cap, thus their name. Waves are present at this location 96% of the time. The wave latitude-local time distribution is shown to be the same as that of the auroral oval. The most intense waves are detected coincident with the strongest magnetic field gradients (field-aligned currents). Specific frequency bands of whistler mode-waves are identified: similar to200 Hz, 1-2 kHz and similar to5 kHz. Two types of intense electric waves are present: solitary bipolar pulses (electron holes) and similar tokHz electric turbulence. The PCBL waves are most likely a consequence of auroral zone field-aligned current instabilities. The currents have in turn been ascribed to be due to magnetospheric convection driven by the solar wind. (C) 2001 COSPAR. Published by Elsevier Science Ltd. All rights reserved. |
