Abstract
Tide-like variations observed in data from an OH spectrometer and MF radar,
co-located at the Buckland Park field station (34S,138E) near Adelaide,
South Australia, over six nights in September 1993 are presented. A
prominent semi-diurnal tide-like variation in temperature with a magnitude
of up to 40 K peak to peak is observed in the OH data. Temperature and wind
amplitudes and phases are compared with a semi-diurnal model, as are the
relationships between the quantities. In addition, the observed
temperature variations are compared with those of previous researchers.
With regard to the absolute values of the amplitudes and phases, the
model and observations differ. However, the observed relationships
between the quantities, in terms of phase, are found to agree well with
the model for four of the six individual nights, as well as for data
which are the average of the six nights.
