WebIn the height region between about 85 and 200 km altitude on Earth, the ionospheric plasma is electrically conducting. Atmospheric tidal winds due to differential solar heating or due to gravitational lunar forcing move the ionospheric plasma against the geomagnetic field lines thus generating electric fields and currents just like a dynamo coil moving against … WebWhy are tides important? •In the MLT tidal winds are as large as zonal mean winds. Wave saturation transfers westward momentum to the zonal mean flow (5-15 m/s/day). •Tides modulate aeronomical species (OH, O 2). •Long vertical wavelengths (27-60 km) makes the tides efficient agents of vertical coupling, and transmission of
