Many people do not see a direct connection between the releases of energy by the sun and the currents of the oceans and winds that flow on Earth. But, there is a direct link between them. Last week, NASA published this animation which shows how that connection works. The sun is shown releasing an explosion of energy called a coronal mass ejection toward the Earth. The Earth is usually shielded from the worst effects by its magnetic field. The Earth is also constantly exposed to light and radiant energy from the sun. Much of this energy is redirected by the atmosphere. Clouds, ice and snow also reflect much of it back into space. What gets absorbed drives the Earth's climate.

The solar heating is uneven due to the variations of the surface. Heat flows from high to lower temperatures. This fact, and the cycles of day and night, and changes in surface heating due to the seasons cause wind currents to circulate around the world. These persistent winds drive surface ocean currents. One of these important currents is flowing off the coast of Florida. It is the Gulf Stream. This river of warm waters is a major factor that drives the climate of the Atlantic and the British Isles.

This 4 minute video is best viewed in full screen mode. It highlights the connection between the energy of the sun and the dynamics that drive this component of the climate of the Earth.

An annual conference, SIGGRAPH, that presents and publishes the best in computer graphics and technical research chose a NASA excerpt from the presentation, "Dynamic Earth: Exploring Earth's Climate Engine," as one of its select entries of 2012.

The Association for Computer Machinery's Special Interest Group on Computer Graphics and Interactive Techniques is known as SIGGRAPH and is widely considered the most prestigious forum of its kind.

"Major Hollywood studios submit pieces, so there is a high standard," says Joshua Grow, SIGGRAPH Computer Animation Festival Chair, Los Angeles. "Clearly NASA has exceeded that standard with their submission."

The full-length "Dynamic Earth" presentation is narrated by actor Liam Neeson and illustrates how equilibrium between Earth's climatic systems sustains life and what could happen if the balance is tipped.

The immersive 24-minute, ultra-high resolution, full-dome show is a joint production of NASA's Scientific Visualization Studio (SVS) in Greenbelt, Md., Spitz Creative Media in Chadds Ford, Pa., the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign, Ill., the Denver Museum of Nature & Science, Colo., and Thomas Lucas Productions in Ossining, N.Y.

"'Dynamic Earth,' the show is also going around the world," says Horace Mitchell of NASA’s Scientific Visualization Studio (SVS). "It's currently being dubbed into Spanish, Arabic, Turkish and Greek."

The show is now playing at the Smithsonian National Air and Space Museum in Washington, D.C., at the Museum of Science and History in Jacksonville, Fla., and will launch at the Museum of Science, Boston, Mass., this summer. The show has also been licensed to more than 20 schools, museums and other locations.

The 2012 SIGGRAPH conference and exhibition takes place Aug. 5 to 9, 2012 at the Los Angeles Convention Center. The "Dynamic Earth" excerpt will be one of only 31 presentations featured in its "Electronic Theatre" during the Computer Animation Festival.

The 4 minute visualization above was also published June 19 as the 100th story for the award-winning NASA Viz iPad application. If you own an iPad, I recommend this app. Another app you will enjoy if you are a space geek is called simply NASA. With it you can access NASA TV, launch schedules, the latest science, videos, and much more. It is one of my most valued apps. I use it all the time.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

    In this segment of Dynamic Earth, the audience dives below the ocean surface and into a swarm of microscopic organisms that hold the key to our climate: DIATOMS, RADIOLARIANS, COPEPODS, and colorful OCTUPUS LARVAE: all rendered in exquisite detail for giant screens. As these creatures fade into the background, the audience finds itself in the middle of schools of JACKFISH and HAMMERHEAD SHARKS, before rubbing shoulders with an enormous HUMPBACK WHALE.

        •  solar radiance varies from about (8+ / 0-)

          1360 to 1362 W m-2.  See which shows the solar radiance since 2003.  See that there are lots more wiggles in the beginning and the end of the time series?  That's the result of sunspot activity, which basically went to nothing from 2008-2010.  One thing I find interesting in the time series is that if you smooth out those wrinkles, there's maybe a 0.5 or so W m-2 decrease from the solar minimum.  0.5/1360 is about 0.04%, and then you have to account for only 1/2 the earth's disk getting hit by sunlight, and much of that at an angle.  Forcing from all greenhouse gas emissions is about a factor of 5 to 10 more than that.

              you're referring to.  Is it about a particular wavelength of solar insolation that changes the environment?  300 nm is ultraviolet, and constitutes about % of the solar spectrum?

              Is what you are referring to from peer-reviewed research?  And do you have a particular axe to grind, perchance?

              Out of curiosity, I decided to do a bit of Googling on this topic.  I note that there has been knowledge of the stronger variations in solar insolation in the 200-300 nm range since about 1990 or so, perhaps further back.  In 1995, Lean et al. found that 0.51°C of the increase in temperature from the Maunder Minimum (late 1600s) to today is accounted for by solar insolation increases, and they state that's essentially in agreement with the climate model response. One-half of warming from 1860 to 1970 can be accounted for by solar insolation. But only 1/3 of the increase since 1970 to 1990 can account for the warming during that time.

              There's one other problem with UV light.  A pretty large proportion of it is absorbed in the stratosphere by ozone.  Impacts nearer the surface are related more to the visible and near-infrared part of the solar spectrum.

    •  No, solar variability is NOT a driver... (2+ / 0-)
      Recommended by:

      ...of climatic variability.

      The video is a bit confused, when it shows a coronal mass ejection, and then talks about the ways that the Earth is "protected" from it.  In reality, those "protection" forces are acting on the solar radiation constantly.  Particles (present in mass ejections) ARE deflected by our magnetic fields, as we see in the aurora borealis (and australis) during these rare, short-term events.

      The other processes described modulate the normal solar radiation.  First, the ozone layer strips away (by absorption and re-radiation) the strongest UV rays.  Much of the sunlight is reflected by ice, snow and clouds.  What reaches the Earth's surface is absorbed, and re-radiation from Earth's surface heats the atmosphere.  Much of the re-radiated heat is trapped by our CO2, which keeps us warm enough to have a habitable planet.  Global warming is another topic.

      At low latitudes, there's more heat entering our system than is radiated back to space, and at the poles, there's a heat deficit.  Atmospheric circulation moves heat from the tropics towards the poles in both wind and water currents to keep the system balanced.  There's all sorts of complications that make the pathways complicated - Earth's rotation, atmospheric turbulence, and topography (on land) and bathymetry (in the oceans).

      Most heat is carried by ocean currents, which are driven by the winds.  The ocean circulation cycle takes years to decades to complete; therefore, any change due to solar variability needs to be decades long as well.

      The 11 year sunspot cycle is just barely long enough to possibly affect our climate, and some climate scientists have attributed some features of our global warming, in part, to sunspots.  Coronal mass ejections are simply too short to have any real impact on climate - they're over too fast, and just get buried in the variability of our climate.

      Human-induced global warming, on the other hand, has lasted for over 150 years, and therefore can and does have a MAJOR impact on our climate.

          I taught at a university for several years, and now work in private industry.  

          I used to teach a physical geography course, which included atmospheric and ocean circulation down to climate and weather - for 20% of the course.  For atmospheric circulation, I had to start with the global energy imbalance, then to the resulting equator to pole wind circulation then to actual wind patterns due to the Coriolus effect, and then to turbulence along the polar front and ocean circulaton driven by prevailing winds - with deep return flow of cold water.

          I had to learn the hard way how to build an argument from the ground up for my non-technical students.

I taught high school physics 37 yrs. and faced the same situations of teaching technical things to non-technical students. It forces you to learn the material more in depth so you can present it clearly.

          In my comment, I argued that changes in solar output on the scale of a coronal mass ejection was too short to have any appreciable impact on the climate.  The 11 year sunspot cycle is marginal, as ocean circulation cycles have a similar or longer period.

          The Maunder Minimum (when the sunspots virtually disappeared between about 1645 and 1715) does match up with the first of three cold periods in the "Little Ice Age".  Since it lasted for about 85 years, it was long enough to have a potential impact on global climate.

  •  off topic story about SIGGRAPH convention (9+ / 0-)

    A long time ago ( late 80's  ) I was working as a Union stage hand in Orange County CA.  I.A.T.S.E. Local 504. The SIGGRAPH convention came came into town at the Anaheim Convention Center and I was assigned to work the arena where the computer generated films competition / showcase was held. This may have been the very first SIGGRAPH convention. The big hit that year was a now famous short titled  Luxor JR . Many of the shorts were on 35mm film and required projection to be shown. Some were on video tape but back then quality was not like it is now. The thing I vividly remember about this show was that there was one of the old time movie projectionists from our local assigned to run the projectors.
    This guy had been showing films for most of his life and was really good at what he did. One of the films had the audio on a separate track that required two "synced" projectors. One for picture and one for sound. There was no rehearsal as was typical for industrial gigs. When that film was shown the sound didn't sync properly and the producer was hopping mad. He was yelling and screaming at the projectionist. He called him every name in the book and accused him of sabotage!
    It turned out that the sync marks provided on the films were wrong and the studio that made the prints was at fault. I'll never forget that night.
    Aside from that, this was a really great show to work. Also, on the older computer generated animation look for patterns on the floors / ground. They needed these for points of reference to help with the required calculations.
