      abstract     = {During the APE-THESEO mission in the Indian Ocean the
                      Myasishchev Design Bureau stratospheric research aircraft
                      M55 Geophysica performed a flight over and within the inner
                      core region of tropical cyclone Davina. Measurements of
                      total water, water vapour, temperature, aerosol
                      backscattering, ozone and tracers were made and are
                      discussed here in comparison with the averages of those
                      quantities acquired during the campaign time
                      frame.Temperature anomalies in the tropical tropopause layer
                      (TTL), warmer than average in the lower part and colder than
                      average in the upper TTL were observed. Ozone was strongly
                      reduced compared to its average value, and thick cirrus
                      decks were present up to the cold point, sometimes topped by
                      a layer of very dry air. Evidence for meridional transport
                      of trace gases in the stratosphere above the cyclone was
                      observed and perturbed water distribution in the TTL was
                      documented. The paper discuss possible processes of
                      dehydration induced by the cirrus forming above the cyclone,
                      and change in the chemical tracer and water distribution in
                      the lower stratosphere 400-430 K due to meridional transport
                      from the mid-latitudes and link with Davina. Moreover it
                      compares the data prior and after the cyclone passage to
                      discuss its actual impact on the atmospheric chemistry and
                      thermodynamics.},
