Four and a half years of data from a meteor radar based at Sheffield, UK, representing measurements of neutral wind velocity in the meteor region above 53°27′N, 3°53′W, are analysed to produce climatologies of both longer-period (2–30 days) n

The harmonic relationship between the diurnal and semidiurnal tides gives rise to an elementary mathematical relationship that has intriguing consequences for secondary waves produced by non-linear interactions between the diurnal tide and planetary

Data obtained from a meteor radar at Sheffield, U.K. (53°27′N, 1°35′W) between 30 June 1989 and 6 October 1994 have been used to study the variability of tidal amplitudes and the possibility that this is caused by non-linear interactions with p

Wind measurements carried out at 6 European sites are investigated to set up a climatology of the semidiurnal tide in the mesopause region over Europe for the latitudinal range between 50°N and 56°N. Intercomparison of amplitudes and phases general

Meteor radars located in Bulgaria and the UK have been used to simultaneously measure winds in the mesosphere/lower-thermosphere region near 42.5°N, 26.6°E and 54.5°N, 3.9°W, respectively, over the period January 1991 to June 1992. The data have
