Observations of polar mesospheric summer echoes resembling kilometer-scale varicose-mode flows

Abstract ∘  N, 16∘  E), uses polar mesospheric summer echoes (PMSEs) as tracers to study MLT dynamics across multiple scales. recently discovered a spatiotemporally highly localized event showing a varicose mode (simultaneous upward and downward movements), which is characterized by extreme vertical velocities (| w | ≥ 3 σ) of up to 60 m s- 1 3 σ threshold, highlighting their non-Gaussian velocity distribution and extreme nature.
