I have just been made aware of this article which seems to suggest
something
I had suspected: that lunar tides are linked with jet streams. The
article
is entitled:

"Equatorial Ionospheric Electrodynamic Perturbations During Southern
Hemisphere Stratospheric Warming Events"

But the abstract says:

"We also compare these data with extensive recent
results that showed the fundamentally important role of lunar semidiurnal
tidal effects on low latitude electrodynamic perturbations during of
arctic
SSW events."

If SSWs are caused by waves in jet streams breaking, then there is some
sort
of connection with lunar tides.

Cheers, Alastair.




Why just lunar tides? the solar component of the tides are half as strong
as
lunar ones

Just been alerted to this article, which may answer your question! I am not
claiming to understand this at the moment, but I expect in a few years time
a simple explanation will become available.
