It's even possible to predict el niños
from the LOD changes.
While it may be possible to torture numerological correlations
from the LOD data and the quasi-periodic SOI or other observations — zonal high wind etc — that corellation only has any possibility of indicating a causal relationship rather than a coincidental one if the physical processes can be defined that operate.
It took me some time to understand what the lower part of that figure shows as it looks very different
from the LOD data itself.
Again, I am sorry I got things completely backwards and thought you were claiming a causal path
from LOD to climate, rather than the other way round.

Finland regained their lead just two minutes later as
Lod converted
from outside the box with a well - taken finish.
«We used the Hierarchical
LOD (HLOD) feature in the engine, backed by Simplygon, to combine regions of the map into single low - poly meshes that could be drawn in a single draw call when viewed
from a distance.
According to the uploader of the video Candyland «
From what I saw, the Remaster offers a little bit better
LOD and (volumetric) fog.
For exhibitions such as 100 Steps to the Mediterranean at the Rose Art Museum at Brandeis University in Boston (2012), The Nation's Groves at Tel Aviv Museum of Art (2011), and Al - Lydd at Kunst - Werke Institute for Contemporary Art in Berlin (2010), he integrated photographs of the ancient Arab city Al - Lydd (today's
Lod) and the surrounding landscape with video featuring three generations
from the Christian - Palestinian community.
In particular, at that link, there is a data series
from JPL that has a yearly average of
LOD going back to 1846 that I was able to get a plot for, but I don't know how to paste it in here.
I found a plot of Length of Day (
LOD) going back to 1954 when atomic time was first instituted at this link: http://www.ucolick.org/~sla/leapsecs/amsci.html That plot shows an 18 year general rise in
LOD from 1954 to the 1972 maximum.
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.
I eliminated AMO
from any fit when I found that the
LOD as described by the Stadium Wave paper is the underlying factor describing the long term fluctuations.
Barring unknown interference
from the likes of core / mantle coupling the
LOD decrease of the last 40 years indicates that melting has decreased and GIA
from the LIA is now winning.
Your calculation is based on the assumption that you can calculate the change in rotational energy
from the change in
LOD.
LOD: length of day as deviation
from 86400s, it's still length of day.
What this means is that 20 years
from now, if we know what the CO2, SOI, Aerosol estimate,
LOD, and TSI measures are, then we should be able to estimate the temperature anomaly.
103, pp. 12639 - 12647,1998) long period (Mf, Mf» and Mm) ocean tidal corrections to the Yoder model have been removed
from this series, as have the subdaily tides, since they have not been added back to the
LOD values reported here.
From which we can derive two obs: 1) If it part of the chain of causality,
LOD is doing more of the causing than it is being affected by the other indices in the list.
It's a small step
from there to understanding the MD waves in
LOD & NH circulation.
There is also the fact that as
LOD is influenced by tidal effects
from the Sun and Moon and ENSO, zonal winds etc are also to some extent modulated by the same tidal effects the same influence shows up in both.
It's stated in the text, but understanding that the absolute deviation of the Earth's
LOD from its long — term trend refers to the absolute value of the deviation
from a linear trend fit, whatever the sign of the deviation.
From my limited perspective two of the strongest arguments against AGW are the
LOD problem and the fact that only ice sheet extension (hence, temperature) explains the correlation between Milankovitch Cycles and CO2 fluctuations in the ice cores; that is, T forces CO2 or both are forced in tandem by ice sheet extension.
From their Figure 1 you can see, how variations in calculated atmospheric angular momentum correspond exactly to the short - term variability of
LOD, but are totally inadequate to explain multi-year variability.
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.
The decadal
LOD variations (e.g., approx. 4 ms around 1900; Hide et al. 2000) are too large in amplitude to be explained by the atmosphere; the largest atmospheric contributions observed are
from the seasonal cycle and El Niño events (approx. 1 ms in amplitude).
Weather you and I agree or disagree it is totally irrelevant, it is not a matter of the opinion, it is fact that the data
from Jault Gire and LeMouel (1990) and later reinforced by Bloxham & Jackson (1992) show that 20 % of the Earth's
LOD variability is closely correlated to the sunspot magnetic cycle.
Hi Steven I wouldn't discard the solar, not as yet (see vukcevic page 6) than take a look at http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/22423/1/97-0910.pdf page 9: The total CAM (core angular momentum) results
from the summation of the individual cylinders with a maximum at a 15 - year lead with respect to
LOD...... (note the -65-year periodicity).
JamesG (04:22:42): I gather
from readings elsewhere that there are Earth processes that significantly lag changes in
LOD and others that significantly lead it.
From the timescale - specific phase - mismatches between
LOD, QBO, GLAAM, SOI, NAM, SAM, etc. we can learn about SOI priming, triggering, etc..
Also, the
LOD / ENSO relationship appears to be hotly contested, so if I were to include it in posts, it would draw
from the points I try to make.
I use a stadium wave component in my own model, scaled against the
LOD changes that Dickey
from JPL proposed as a temperature proxy.
I found that when
LOD data is added to integrated sunspot numbers departing
from the long term average, a curve can be produced which matches the sea surface temperature record
from 1850 significantly better than the co2 curve does.
Paul That
LOD comment came
from a misfortunate statement in a European article on
LOD noting a leading phase shift for
LOD vs another parameter.
Dr. Scafetta I thought it was clear
from the graphs I linked: http://www.vukcevic.talktalk.net/Spectra.htm — First graph: there is no obvious 60 year component in the Global, Northern Hemisphere, CET and
LOD (2 CET periods show problems of a short data set, where apparently single component is dissolved into three distinct CET periods of 55, 70 and 90 years).
By the way, I've worked out a method of reconstructing global SST
from sunspot numbers and
LOD variation which shows:: a) The wartime issues with engine cooling inlet sensors still isn't sorted.
LOD saw UK profits rise
from # 15,000 to # 2m last year, as the flexi - lawyering business boosted turnover by 16 % to # 16.9 m.
Pictured: host Tiff Stevenson; Tom Hartley, managing director,

Further, in 2010 Berwin Leighton Paisner won the awards for Law Firm of the Year
from both The Lawyer and the British Legal Awards, each of which prominently cited
LOD as a key factor in the win.
Perhaps the most succinct description of
LOD came
from The Lawyer's write - up of their 2010 Awards: «Lawyers On Demand is the way things are going».
