http...<i>"Here is my take on a mechanism for QBO <br />http://contextearth.com/2016/01/27/possible-luni-solar-tidal-mechanism-for-the-chandler-wobble/"<br /></i><br /><br />I messed that up, it should read "Here is my take on a mechanism for the Chandler wobble".<br /><br />The QBO got inserted there because the same mechanism that is driving QBO may also be driving the wobble, which is the Draconic lunar cycle.<br /><br />The Chandler wobble has a period of 1.185 years while the QBO is 2.37, half as fast. This can be reconciled if one considers a symmetric (North vs South) declination forcing versus an asymmetric forcing.<br /><br />Of course correlation does not equal causation, but this is one of those cases in which an agreement with a plausible theory does not allow one to rule out that theory. For example, if those numbers were just a little off, one could rule out the lunar cycle as a forcing mechanism. <br /><br />There is also this recent paper on finding a correlation between upper atmospheric rainfall and the Lunar cycle "Rainfall variations induced by the lunar gravitational atmospheric tide and their implications for the relationship between tropical rainfall and humidity", Kohyama & Wallace http://onlinelibrary.wiley.com/doi/10.1002/2015GL067342/full<br /><br />What motivates this analysis is the confliction between the moon being responsible for as significant an effect as oceanic tides, but not much else.

I haven't received an answer yet so I'm assuming no obvious errors. And what @whut said. This might indeed be an essential part for simulating natural variability in climate models.jyyhhttp://erimaassa.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-5337555368793819627.post-59872011281238107092016-01-21T12:00:24.541-05:002016-01-21T12:00:24.541-05:00The Chandler Wobble, QBO, LOD variation, ENSO, Ang...The Chandler Wobble, QBO, LOD variation, ENSO, Angular Atmospheric Momentum, and oceanic and atmospheric tides all have varying degrees of connection, likely ultimately tied to luni-solar origins. <br /><br />Keep plugging away at what you are doing because there are likely common origins to much of the behavior. If you can figure it all out, it will be useful in establishing the natural variability in climate, and thereafter the GCMs can then use this information in their models.<br /><br />@whuthttps://www.blogger.com/profile/18297101284358849575noreply@blogger.com
