Resulting in Angular momentum and
LOD changes, Well, putting them back in did not help.
I use a stadium wave component in my own model, scaled against
the LOD changes that Dickey from JPL proposed as a temperature proxy.
It's even possible to predict el niños from
the LOD changes.
Therefore, the hypothesis that the climatic changes are a consequence of
the LOD changes should be rejected (Lambeck 1980).
(1) terms due to PDO as linked to
LOD changes will never add more than + / - 0.1 C to the global temperature record
I have already shown above Nino1.2 SST seems to sit on top of a variation that matches closely to
LOD changes.
I matched a lag of about 7.6 years between underlying SST and
LOD changes, this suggests a dominant cycle of 4 * 7.6 = 30.4 years.
[Response: The only graph I see claiming to be a history of GS variations is labelled «LOD» — thus I assume that Moerner is equating GS variation with
LOD changes (possibly I'm wrong, but you would need to find the original publications to check).
That would fit with the sun building up that temperature imbalance either side of the equator then
the LOD change (perhaps in conjunction with other factors) triggering the next ENSO event.
The ~ 86 % of low frequency
LOD change being attributed to interactions within the Earth's interior is incorrect.
Short term
LOD change is almost entirely due to interactions between ocean mass and solid Earth, for one reason or another.
As the paper says (citing Gross), the changing AAM and oceans, precip etc can only account for 14 % of low frequency
LOD change.
Not exact matches
And yes, we'd even relish the chance to see it rendering with a 4K texture pack, with other tweaks and
changes in
LODs, effects, lighting or shadows.
Initially called XT -
LOD (Extension Lock - Up Overdrive) its name was
changed when revisited in 1974 to FIOD (Ford Integrated Overdrive) and then to its final name in 1979, the Ford AOD transmission.
The distance for
LOD's are
changed, the types of texture filters, the distance of texture filters, levels of tri-linear mappings, etc..
But for example, the zoom ratio of the
LODs are
changed, which is a coding part.
And yes, we'd even relish the chance to see it rendering with a 4K texture pack, with other tweaks and
changes in
LODs, effects, lighting or shadows.
Gavin, I have no opinion about the
LOD as source / result of
changes in flow / ocean levels, which appears to me as mainly of academic interest.
That report concludes that seasonal
changes in
LOD are due to interaction of the earth's atmosphere and mantle.
From http://en.wikipedia.org/wiki/ΔT»... the net acceleration (actually a deceleration) of the rotation of the Earth, or the
change in the length of the mean solar day (
LOD), is +1.7 ms / day / cy.
Vaughan Pratt told how much water must be moved to make an effect in
LOD, I told how much the winds must
change, your enthalpy calculations are not well defined.
Earth is massive and it takes something comparable to
change the
LOD even by a few milliseconds.
Your calculation is based on the assumption that you can calculate the
change in rotational energy from the
change in
LOD.
LOD can't
change the upwelling in the east pacific, dLOD can, so SST / dLOD correlation seems logical to me.
(The main result of the paper is that lags between
changes in
LOD, AAM and OAM are not significant, thus no additional mechanism are needed to explain such lags.)
Sometime I might publish my article with analysis: Abstract
Changes in the length of day (
LOD) have number of causes, some more certain than others.
I don't think that any part of the heat energy released through dissipatien related to
changes in
LOD is of any relevance.
Gross already calculated that redistribution of water can only account for 14 % of low fequency
changes in
LOD.
In the short Sidorenkov Wilson paper, they note that the
changes in the
LOD precede those in the Pacific Decadal Oscillations by 8 years or 96 months.
That still leaves the question of what is causing the
change in angular momentum reflected in the
LOD data.
LOD is a lagged proxy for the actual driver of the
changes — and EM coupling between the IMF and Earth's magnetosphere and core magnetic field.
I think that the observed length of day is more real than the
lod measured by radio telescopes using distant quasars, the fact that the Earths orbit is elliptical and that the Earth is inclined to the rotation gives us real
changes here on Earth (just because something is more accurate does not mean more relevant).
The
changes in
LOD are probably something like microseconds per year, which makes the idea that it affects climate laughable.
These are really close to the 2.4, 3.6, 4.7, and 6.2 that you find in PSD of the rate of
Change of
LOD.
The
change in kinetic energy due to
LOD modulation is huge and that energy has to go somewhere.
This confirms my earlier impression that long term
change in
LOD could account of ENSO events.
The sum (integral) of this effect over time will be shown in
LOD (not it's rate of
change), so decadal scale
change in SST will be reflected in
LOD.
Number of researchers have investigated relationship between
LOD and the climate
change.
Web, If you want to look into
LOD's connection to temp anomaly, you need to look at Daily average temp numbers by year and examine the rate of
change in temp as the seasons progress.
It's a discrete approximation to rate of
change: d / dt (
LOD).
With both annual and decadal
change in
LOD lagging
change in SST it is difficult to see
LOD as driver.
Except that we know from the paper itself that the surface phenomena aren't causing more than 14 % of the multidecadal
change in
LOD.
As other posters have indicated with the point about how ice lost from ice - caps
changes the angular momentum, the movement of water and atmosphere over the surface has an impact on the angular momentum and therefore a major ENSO event will show up in a
LOD fluctuation.
If your model is true, the rate of
change of temperature is independent of SOI,
LOD, and TSI.
Changes in
LOD are controlled primarily by Jupiter, and the proof is incredibly simple, as my paper will show if it gets accepted.
Ah yep that would
change Saturns
LOD.
Whatever the contribution of solar variability to
LOD is, it does not
change the fact that outer planets can not affect the inner solar system trough magnetic fields because the plasma of the solar wind makes the magnetic effects unidirectional.
I am just demonstrating that there is enough coupled energy in the system by the
changes in
LOD to be able to affect
changes.
One - way interaction where the
changes in
LOD are causally connected to
changes in the geomagnetic fields and they affect climate is easier to contemplate than two - way interaction needed in the idea of stadium waves, but I'm not convinced of any causal connection.
There is a 15 year delay between the
changes in the angular momentum of the Earth's inner core (where magnetic field is generated) and the
LOD (length of the day) NASA and the Oxford University scientists in 1997/2000 published paper on the effect: Torsional oscillations of the Earth's core http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/13763/1/00-0133.pdf
