Every time lightning strikes, a huge assortment of stuff is released. We're all familiar with the usual flash of light and sound, but what you probably didn't know is that lightning releases a huge burst of radio as well. This type of radio, known as VLF radio, is some of the strangest there is. By converting this radio directly to sound we hear a cacophony of sounds, from pops and click, to animal like chirps and even strange sci-fi sounding noises. There's lot of other phenomena that can also produce VLF radio like this and by learning what each sound is, and when to listen for them, you can learn a lot about what's going on on earth.

I've been fascinated by the idea of listening to electromagnetic signals for years. For those interested, it seems to be possible to hear the noise local lightning makes by tuning to an otherwise empty spot on the AM radio band. In my car, I've picked up what I think is the noise of lightning (sharp bursts of static), the hum from powerlines, and noises from those vehicle-detection loops in roads. And a handheld AM/FM radio will pick up stuff like the noise from switch-mode power supplies quite nicely, too.

I always wondered how that was done. It seemed like black magic to me and I never managed to stumble upon the methodology. Thanks for finally answering my questions. Also, thanks for the links, I'm going to spend a lot of time listening to these in the background.

Lightning generates a spectrum of noise, from the MF to the VLF band. The higher frequency noise pulses are attenuated more rapidly and this is a method of determining the distance to the strike. There are small devices tp clip on the belt for use outdoors, hiking, mountain climbing, golf etc, which detect the MF and LF noise and give an approximate distance.

Damn, it was so interesting walking around the house with some earbuds plugged in, powered from a small battery and just pointing the antenna at things to hear their radio emissions.

A lot of time and money was put into it back when we had the polaris missile (nuke capable) on the trident sub as a first launch capability near the end of the cold war. For its time it was very impressive. It also included a 11 mile long antenna array in colorado you might look up. You might enjoy it.

If you’ve ever seen ferrofluid under influence of a magnet, you can see that there are regions the fluid congregates towards and forms pointy nodes which depend on the strength and location of the field. The regions and nodes can be remarkably consistent with respect to the location and strength of the magnet. You can almost always predict where the fluid will flow to if you’ve seen the same state (of the magnet wrt. the ferro fluid) before. Now, are those places/points of congregation where those pointy nodes show up actual, physical “field lines”? I’m not sure, but it is tempting to call them that. (edit: typo/parenthesis)

Lightning, aka "whistlers' mother" . . . A nice summary focusing on ground-based VLF recordings. I host a historical archive of Steven McGreevy's material at www-pw.physics.uiowa.edu/mcgreevy Two minor corrections to this video: The "dawn" in dawn chorus doesn't really have anything to do with local time; it's merely a reference to the morning song of jungle birds that the signals sound like. Also, it's my understanding that the VLF emissions don't push away the Van Allen belts, but drain it near the Earth. Also, if you want to hear similar space audio recorded by spacecraft . . . you know where to look.

How can you possibly pick VLF under ocean, when the ocean's salty water is incredibly conductive (and you've mentioned in the beginning that it's a very good reflector)?
@invendelirium 4 жыл бұрын
A bit later, I thought that while electric field is screened very well by the conductive water, the magnetic field can potentially penetrate a lot deeper. How much deeper? Well, that is called "skin depth", and it can be easily calculated given the resistivity and the frequency. For ocean water resistivity, I found a value circa 0.2 ohm*m. For 1kHz, I calculated the skin depth to be 7 meters. So, a submarine whould be able to pick something up, but only if it is quite close to the surface. Below 20 meters it should fade to nothing.
@thethoughtemporium 4 жыл бұрын
The conductivity just tips the wave a bit so it can curve enough to not leave the atmosphere, doesn't really impede it, so it penetrates water just fine. Also, not much of the energy of a lightning bolt ends up as VLF. It's enough to pick up, but not a huge amount. Whereas for military stuff they blast copious amounts to get it where it needs to go. Also a lot of the reason radio has issues penetrating the ocean is because of the air water interface. Once it gets past that it can travel further. VLF mostly ignores this interface so it's already in a good position to keep traveling.
@invendelirium 4 жыл бұрын
@@thethoughtemporium And what's the deal with the interface? Is it too reflective? or too irregular? As for reflectivenes, VLF seems to be the point where it's the highest, as it is where dielectric permittivity of water is the highest (circa 100, so refractive index is 10). So it's worst for reflectivity. Then in the microwave it drops and gets a high imaginary component, meaning high absorption coefficient. then we are approaching the light territory...
