variability and weather prediction in the Earth’s atmosphere,
measurements of winds, temperature and wave activities are very
crucial. The Earth’s atmosphere is believed to act as a source
and sink for the waves of a broader spectrum with periods from
few seconds to years. Generally, the Earth’s atmosphere is
stably stratified except the planetary boundary layer and thus
makes a reasonable assumption for the presence of atmospheric
waves. A barotropic atmosphere in a resting basic state is able
to support these spectra of waves. These waves move diagonally
upward or downward and horizontally. The mean zonal circulation
is mainly driven by these atmospheric waves, which are believed
to be generated in the troposphere and propagates horizontally
and vertically in to the middle and upper atmosphere. These
waves transport energy and momentum from one region to another
without the transport of material medium thereby impinging the
signature of the source region
