Abstract
Lower-stratospheric layered structures of a few kilometers in thickness observed mainly by rawinsondes and MST radars are reviewed. Multiple tropopauses and temperature significant levels are found in the data of rawinsonde observations, whereas wind fluctuations associated with quasi-monochromatic internal inertio-gravity waves are analyzed from the MST radar observations. These two features are identified by several case studies, and a preliminary theoretical approach to explain the origin and role of them is presented. A poleward flow is induced and maintained by this structure, which is considered to compensate a vertical velocity field induced by an imbalance of the radiative-convective equilibrium in the troposphere.
