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. WebFollowing the mathematical development of Chapman and Miller, Tschu has described a practical method of determining the lunar diurnal variation of geophysical elements.
