Dynamical processes and correlations at midlatitudes in the lower and middle atmosphere Original Research Article

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.
