Interhemispheric coupling aspect at Davis, Rothera and Rio #11

Sato et al (2016): According to Yasui et al. [2016], who examined 15 year observations of horizontal winds by the MF radar at Syowa Station (69.00°S, 39.35°E), the relationship between wind variances associated with mesospheric gravity waves in the SH and a sudden stratospheric warming (SSW) in the NH is not statistically significant, at least not over Syowa Station. Therefore, while the existence of the interhemispheric coupling phenomenon is widely accepted, the mechanism coupling the stratosphere of one hemisphere to the mesosphere of the other hemisphere is still unclear. Further studies on mesospheric gravity waves in the SH are needed in order to elucidate the mechanism of the interhemispheric coupling in the middle atmosphere. Related to #6.

Check whether interhemispheric coupling is invariant during SSWs in the southern hemisphere (SH), i.e. produce composites for SSWs in the SH (depends on #24).
