Hi all.

I'm reading up on types of atmospheric motion, and when discussing the
meridional transport of various properties the motion is generally split
into three components:

1. Mean meridional circulation
2. Transient eddies
3. Stationary waves

However, depending on what book, article or website I read, I come
across the terms transient eddies, stationary eddies, travelling waves,
stationary waves and non-travelling waves. Is this just a case of
different terminology for the same thing, or are there specific differences?

Are transient eddies and travelling waves the same? Are stationary
eddies, stationary waves and non-travelling waves the same?

Thanks in advance!
