UAH Temperature Anomaly Video

Posted by Jeff Id on November 2, 2009

More experience makes better videos.  The following are two UAH TLT (lower troposphere) temperature anomaly videos.  There is a ton of detail in them, you can see the 1998 temperature spike – some have had questions as to where this spike came from.  You can also see the recent cooling wave, Ryan O noticed the oscillation back and forth between the poles.

The first video is high speed and came out quite good.  I’ve worked out some of the video compression difficulties and am producing higher quality videos now.  The 10 fps is just for viewing bulk properties and is way too fast to see small details.  The 5 fps video is much better for watching detail.

The next video is the same thing at a lower frame rate which caused youtube to hesitate every few frames.

    Fascinating. The faster frame rate shows the extreme swings in temperature better, mostly north and south of +-30 degrees latitude. Why would the anomalies be more extreme in the higher latitudes? Could this be associated with the satellites used?

  2. Layman Lurker said

    Very interesting dynamics. Especially comparing patterns in tropical vs higher latitudes.

  3. #1 Extremes always seem to be associated with the colder end of things. Nights vs days; winters vs summers; polar vs equatorial and temperate.

    Jeff, great. Interesting to see 1998 El Nino spread. And would it be possible to view the sequence even more slowly? What comes across is an incredible homeostasis at work that never seems to allow extremes to go too far before bouncing back. Another thought that comes through is, how far is the planet affected by bombardment from space? like what the Sudden Stratospheric Warming did earlier this year.

    #3 Thanks Lucy, Geoff S was wondering where the huge spike in 98 came from. Now you can see it. I’ve got plans to add multiple globes in the same video.

    “I’ve got plans to add multiple globes in the same video.”

    Can you rig up a view from the poles? Given all your work on Antarctica, that would be very interesting indeed – especially the seasonal changes, geographic patterns, oscillations, etc.

    #5 I totally can do that, unfortunately the sat’s don’t really cover the poles and you’d just be looking at infilled versions. You never know people’s backgrounds in blogland so please forgive but I think this comment could do well for others if not for you.

    When you see the big screen plots at NASA of the shuttle or ISS in orbit you can see the sinusoidal pattern of the orbital path. This happens despite the fact that the ISS or shuttle are often in very circular orbits. Really good quality circular orbits around the center of mass of earth. Circular is very useful for instruments. The inclination (angle) of the circle determines the peak to peak amplitude of the sine wave plotted on Nasa’s big screen. The earth revolves in 24 hours, low orbit is 1.5 hours. When you visualize a ring around the earth, unless the angle of the orbit reaches perpendicularity to the equator it’s difficult to reach the poles of earth. I say difficult because sats can change their pitch and yaw to point instruments so if you’re close to the poles the instruments can be angled to get the rest. I suspect other instruments than temp are taking some precedence in that the sat’s are not achieving polar orbit. Kinda funny considering that we’re talking about flushing trillions of dollars and likely starvation of the poorest to prevent ‘global warming’.

    Anyway, I can do some really cool revolving earth video’s and all kinds of things but the data isn’t quite there. Maybe I’ll do it anyway.

    I was aware of the polar “holes” in sat coverage but your explanation was very clear in why this occurs. How does UAH infill for these holes?

    Layman – not sure if this will help or hinder but there was some stuff on how GISS handles this a while ago on RC:

    http://www.realclimate.org/index.php/archives/2008/11/mind-the-gap/

    This is the blurb – enjoy!:

    “If we want to relate global temperature to global forcings like greenhouse gases, we’d better not have a “hole” in our data set. That’s because global temperature follows a simple planetary heat budget, determined by the balance of what comes in and what goes out. But if data coverage is not really global, the heat budget is not closed. One would have to account for the heat flow across the boundary of the “hole”, i.e. in and out of the Arctic, and the whole thing becomes ill-determined (because we don’t know how much that is). Hence the GISS data are clearly more useful in this respect, and the supposed pause in warming turns out to be just an artifact of the “Arctic hole” in the Hadley data – we don’t even need to refer to natural variability to explain it.”

    Jeff – feel free to cut the above (and this), it doesn’t add anything. Pleased to see some sort of dialogue with DO on the other thread. C

    # I cut almost nothing so be careful. hehe.

    #7 Dr Christy has an explanation somewhere but I don’t remember. I’ll look for it when there’s time.

  12. curious said

    Fair enough🙂

    Thanks for the links. So GISS does an EOF analysis for the arctic data holes. Sounds interesting and worth reading up on when time permits.

    Jeff,

    Many thanks for the global picture of the 1998 high. It just seems to appear, mostly in the tropics and sub-tropics, in a month, sit there for 3-4 months, then go away.

    Especially regarding GHG, how can such a global change happen when the GHG scarcely changes? The 2 main alternatives are instrumental/adjustment error and solar irradiance. Can anyone think of others? They have to act globally and virtually instantaneously, coming and going. The rise and decay times seem to be of the order of months.

    A general comment is that the global variabilty as seen in the animation over the years seems most concentrated in polar regions, where the measurements are worst. This might be related partially to grid cell size as well as satellite coverage, but it adds little cause for alarm about global warming. Most of the rst of the globe seems to behave itself quite well, month by month, year after year.

    Final Q: Is the monthly difference between USA and Canada observed on greater than a random frequency? At times it seems you can almost draw a line along the border. More adjustment suggestions, anyone?

  15. Jeff, the following gives more ground for my suspicions/interest/hunches re the homeostasis AND fluctuation this incredible video seems to show.

    Rather belatedly I read through the WUWT post by Leif. I was astounded to follow through Dr Gerhard Loebert’s comments (02:31:10 on 2nd November) esp. this ICECAP pdf. I think this man is on to something big. He shows an extraordinary correlation between length-of-day (LOD) and climate, over a 60-year period, with LOD leading climate by around 5 years. He suggests this is a “smoking gun” for a lot more, effectively a revision of Einstein’s General Relativity Theory.

    Even if Loebert too has his personal limitations. I’ve long had my suspicions that even back of Svensmark is something deeper in the line of “causation” and that it has to do with quantum physics, Zero Point Field material – as Lynne McTaggart explains beautifully in her book of that name, and as I’ve seen other incidental evidence for elsewhere.

    I’m certain that astrophysics / ZPF is ultimately going to unravel and elucidate the prime drivers for climate. Not just the Sun but behind that, the SSB. Not just the SSB, but behind that, the galactic centre. And always, statistically significant correlations necessary first, and likely to precede explanations of causation.

    I’m going to contact Dr Loebert.
