Abstract | This work presents blocking diagrams analysis for the vertical propagation of small scale gravity waves observed over Commandant Ferraz Antarctic Station during the winter of 2017. The wave blocking diagrams are constructed by using the neutral winds obtained at several distinct atmospheric layers, from troposphere to the upper mesosphere, which absorbs the momentum of the waves when wind speeds are higher than the wave phase speed in the waves propagation direction. The waves were visualized from an all-sky imager, in the airglow hydroxyl near infrared emission (OH-NIR), from ∼700 nm to 900 nm, at altitude near 87 km. The physical parameters of the waves are obtained from applying a twodimensional Fast Fourier Transform (FFT) in a selected region of a given set of images where a wave event is clearly identified. The vertical propagation analysis of the small scale gravity waves is conducted by using a blocking diagram, which is the superposition of the wind components from all atmospheric layers comprising the mesosphere, stratosphere and troposphere. The wind utilized for preparing the blocking diagrams is an average wind calculated with nocturnal wind profiles. This average is taken with only a few nights (where there were observed waves) centered on the new moon day, and such average corresponds to the observed month. The wind database used in the averages was obtained by ERA-5 reanalysis from the ECMWF. In this work it will be presented the blocking diagrams for the months of April, May, June and July in the year 2017. The blocking diagrams well represent the wave filtering, showing the preferential propagation direction of the waves observed in the mesosphere, that is, the waves that reach the mesospheric height propagates in a different horizontal direction from the average wind in all altitudes levels below the observed layer. |
