Everything Is Upside Down In Oz

Besides the fact that have strange stars and their toilets flush the wrong direction, Australian temperatures are out of phase with US temperatures. Australia cooled from 1880 to 1950, and has been warming ever since. The US pattern is basically opposite that.

One of the causes of this is the eccentricity of the Earth’s orbit, which affects the length and intensity of seasons. Earth is currently closest to the Sun during January, which causes a short, intense summer in Australia, and a long, less intense summer in the US when the planet is furthest from the sun.

What other factors cause this phase relationship? Enquiring minds want to know.

    Might also have something to do with the Northern Hemisphere having more landmass. Just guessing..

    better adjustments by BOM?

    It’s because the toilets flush in the wrong direction … it screws up everything!

  4. Steven, you have a longer time period for Australia. If you lop off the part that does not have results for U.S ( < approx. 1892), the series are much less incongruent. The latter-day divergence is explicable by the Australian data having much more UHI than the U.S. data, meaning that even though the U.S. data are "adjusted" in the wrong direction, there is still a significant divergence between the two countries. That leaves the earlier period (~1892 to ~1920) to explain.

    I notice that in this entire ~28 year period, the difference between the two is the greatest at the very beginning (~1892) and then consistently abates until the final convergence of the two series in approx. 1920. That maximum difference in ~1892 appears to be about 0.70°C or 1.26°F.

    Is not the most material factor, the possibility that, at that time, the two countries simply lacked sufficient coverage to permit their respective mean temperatures to be estimated with an uncertainty of less than ±0.63°F (or half the total difference in 1892)?

    Moreover, I remember you recently demonstrating how the use of anomalies is invalid in the U.S., but actually valid in Australia. I can’t quite remember the reason. Was it because of better continuity of station data in Australia? Perhaps that is another factor in the temperature diversity from 1892-1920.

    Milankovitch cycles may have a tiny effect.

    Lunar libration may effect volcanic activity, though I don’t know what cycle that occurs over.

    You guys keep forgetting about deep ocean heat!!

      Hey Robertv! I am maybe confused whether the Y axis (offset) is showing longer days or shorter days. Are days getting shorter? If the polar ice were melting, then days should be getting longer as mass moves toward the equator.

    Sorry wrong Sun

    “What other factors cause this phase relationship? Enquiring minds want to know.” I’d say the major ocean cycles play a big role, the Pacific Decadal Oscillation, and the Atlantic Multidecadal Oscillation…

  11. Sparks says:

    Well done! Of course it’s orbital. Prepare yourself for the “astrologist” and the “cycle mania” ad hominems. 😉

  12. Sparks says:

    Also, lets not forget the clear planetary signal in the sunspot record.

    This is the more prominent signal I’m currently studying.

    • Joe says:

      Going to be interesting what happens next in that graph, Sparks. Astrophysicists are predicting a low sun cycle in the coming decades…

      • Sparks says:

        That’s tricky. I’m open minded looking at the orbital mechanics of it all, the timing of the mean anomaly of the orbital ellipses ticks over nicely on the sunspot record. One of the test forecasts I’ve made using orbital data shows the next solar-cycle as being slightly greater than this one but still a week solar cycle. I’ve also plotted the orbital indicator above back to the 1600’s, there’s a good probability of very weak activity after solar cycle 25..

    The real cause is that the blood rushes to their heads down under!

  14. Steve, have you found any relationship between hurricane frequency NH and NH/SH temperature phase? I suspect those are also linked.

    The earth’s eccentricity is not as great as you’re implying with this as being a “cause” for these cycles. The eccentricity will cause the perihelion to be opposite in 10,000 years. Why would this –the fact the earth is 5 million miles closer to the sun in January than it is in July (~3% of the distance) — cause a warming trend on one hemisphere and a cooling on the other? I would expect no visible trend whatsoever, even if there are differences in climate as a result of the distances. The earth’s eccentricity has nothing to do with that. It takes ~55 years for the perihelion’s average day that it is on to advance by one if it’s going to be 10,000 years before the apsidial procession makes it the opposite of today http://en.wikipedia.org/wiki/Milankovitch_cycles

    Also the toilets do not flush backwards in Australia. Well, perhaps some may but it has to do with how the jets are positioned. Giant tubs with hundreds of gallons of water will have the coriolis force act on them but not a toilet. http://en.wikipedia.org/wiki/Coriolis_effect#Draining_in_bathtubs_and_toilets
