| Zusammenfassung |
| A numerical model has been used to calculate
the atmospheric response to forcing at periods in the region of 12-13.5 h. The
results show that the response is enhanced in the neighbourhood of 13 h. These
results have been compared with lunar tidal analyses of mesospheric wind data
and geomagnetic variations at a number of stations. It is found that the N2
lunar tidal component (period 12.66 h) is significantly enhanced relative to the
main lunar tidal component M2 (period 12.42 h) in both types of data,
compared with what would be expected from the gravitational tidal potential.
This supports the predictions of the numerical model. An appreciable phase shift
is also found in the experimental data between the N2 and M2
tides, agreeing in sense with what would be expected for a resonance at a period
around 13 h. |
