Web18 mrt. 2015 · Atmospheric tides in the MLT Tidal oscillations in winds and temperatures are prominent features of the MLT. Periods of 24 (diurnal) or 12 h (semidiurnal) dominate. Careful averaging allows the 8 h (terdiurnal) and even lunar tides with a period of 12.4 h to be observed. Tides are usually classified as either migrating or non-migrating. Web• The ionosphere is the upper atmosphere region containing large concentrations of electrons & ions due to ionisation of the atmosphere by solar UV & X-rays • Such a plasma has a characteristic (i.e. resonant) frequency of oscillation – Ions are much more massive than electrons, so we can neglect ion motion The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere.
