Sound Waves From the Northern Lights Jada Maxwell Photo civility of Bjorn Jorgensen, 18 January 2005, close Tromsø, Norway http://www.spaceweather.com/aurora/images2005/17jan05/Jorgensen1.jpg

Slide 2

"Cooperative energy implies conduct of entire frameworks unpredicted by the conduct of their parts taken independently." - Buckminster Fuller

Slide 3

Can attractive waves in the aurorae change into sound waves? What makes the aurora? Sound waves from the aurora Wave change on the Sun Beginning to answer my inquiry

Slide 4

What makes the aurora?

Slide 5

The aurora is made by a chain of occasions, starting with vitality from the sun. Chain of Events Image affability of Tom Michalik http://faculty.rmwc.edu/tmichalik/solarwind.htm

Slide 8

South-North Magnetic Orientation of CME

Slide 9

North-South Magnetic Orientation of CME

Slide 10

Magnetic Reconnection on Dayside of Earth

Slide 11

Magnetic Field Lines are Drawn Back to Magnetotail

Slide 12

Magnetotail is Compressed

Slide 13

Magnetic Reconnection in Magnetotail

Slide 15

Particles 2 Particles Spiral Down Field Lines Collide with nuclear and atomic oxygen and nitrogen Emit vitality as light

Slide 16

This Creates the Aurorae Northern Lights = Aurora Borealis Southern Lights = Aurora Australis Image kindness of Shawn Malone http://www.lakesuperiorphoto.com

Slide 18

Can we hear the aurorae? Episodic confirmation of auroral sounds murmuring, popping, crackling, swooshing relates with movements of light

Slide 19

6 minutes Sound would take no less than 6 minutes to fly out from the aurora to the ground No recordings of capable of being heard aurorae

Slide 20

Explanations of Audible Sounds Psychological Freezing Breath "Brush release"

Slide 21

Evidence of Infrasound from Aurorae Humans can hear somewhere around 20 and 20,000 Hertz (Hz) Infrasound is underneath 20 Hz Currently being researched Gas extension

Slide 22

The Sun Creates Sound Waves

Slide 23

Sound Waves on the Sun Created by Convection

Slide 24

Sound Waves Propagate through Sun's Atmosphere Sun

Slide 25

Energy of Sound Waves is Transformed into Magnetic Waves Sun

Slide 26

Types of Magnetic Waves Alfvén waves (s-mode) Magnetosonic waves (p-mode) Images affability of Georgia State University http://hyperphysics.phy-astr.gsu.edu/hbase/sound/tralon.html BBC activitys

Slide 27

My Question Can attractive waves in the aurorae change into sound waves?

Slide 28

Magnetic Waves Earth

Slide 29

Transform into Sound Waves Earth

Slide 30

Finding Beta Gas (climatic) Pressure Beta = β = Magnetic Field Pressure β = 1 ?

Slide 31

Resonance All material has a recurrence that it vibrates at Matching the recurrence permits the material to assimilate vitality Singing wine glass

Slide 32

Resonance in the Aurora When β = 1, Energy from attractive waves can be exchanged to the environment Found the right recurrence

Slide 33

When Beta = 1 β = 1 ? At 120 km Near base of aurorae

Slide 34

More Questions to Investigate How does β fluctuate? Contrast gas extension hypothesis with wave change How much may Alfv é n and magnetosonic waves each add to this impact? Which will probably change?
