The wave structure of the zonal circulation has been investigated within the height intervals 1,5 - 12 km, 1,5 - 22,5 km and 80 - 110 km for the spectral region corresponding to the time scales characteristic for the planetary waves (2-30 days). The coherent wave structures in the lower and middle atmosphere have been found to be seasonally and interannually dependent and also show variations with height. © 2001 COSPAR.
