Abstract : A system of linearized equations is developed for the analysis of the interactions between the troposphere and the stratosphere. Ultimately, the meridional disturbance of the seasonal zonal state is described by a second-order differential equation with variable coefficients. Applied with modifications to the analysis of free atmospheric oscillations, it indicates that the existence of interrelated processes in the atmosphere and troposphere essentially depends not just on the scale of the process, but also on the mid-seasonal wind velocity and atmospheric stability. A coefficient of refraction from weather rocket data was calculated for mid-latitudes of the USSR, using the Rossby formula. Near the tropopause, this coefficient has a sharp discontinuity. A qualitative analysis of the coefficients distribution pattern enabled the modeling of the formation of barrier layers. It is conceivable that better understanding of the role of barrier layers will explain the formation of warmer regions at high altitudes and the 'explosive' nature of energy expansion upwards. The calculation involving a rough approximation of the refraction factor indicates that the strong meridional winds at mid-latitudes of the European USSR may be caused by the expansion of the meridional component from the troposphere into the stratosphere.
