Just to test the Idea, it would be a test, to go out to an open field and take my mixer and mics and set them in different points on the open field and have my recorder on and head phones and see what happens see if the mics pick up air waves sound as air moves over an open field and see what is happening in different sections as air passes the mics... Now a regular breez may be hard to hear, now if there is a stedy wind blowing I should be able to capture it on sound that would leave a sound wave... Now a thermal passing should sound distorted with lots of wind to back it up.


So, let say Bob, That you are flying with your glider, don't you feel the wind blowing in your face, or when a thermal hits you wing you don't hear it and feel it? I have been up high before and I heard the sound and felt it when it almost fliped me over, I thought Godzilla was blowing my glider downwards... I think are has different decibels, just like a singer in to a microphone. wind blow at different speed, this: the howling wind blows across the moor

One of the things that I tell new pilots is to imagine the size of the gorilla that could hold your glider in the air for 4 hours (my longest flight to date). Imagine how strong that gorilla would have to be to just hold you up there for 4 hours!!

Those are the forces that you're dealing with when you hook yourself into a hang glider (or even a paraglider). You have to respect that force and manage it at every instant of your flight and even your ground handling. If you let up for one second, that gorilla will get the upper hand and you'll be tossed.

I don't know if the sound you measure on the ground is the same as what you'll hear in the air. That's probably my biggest concern with the idea. It's not clear to me (I don't know one way or the other) whether air moving against air will create much (if any) detectable sound. If you're relying on sound from the ground, then it might be harder to detect the location of the source and even harder to detect the location of the thermal a few thousand feet up.

Having said all that, I think it's great to be thinking about it and even talking about it. If nothing else, it's a good excuse for me to share my gorilla example with you. Be careful, because you don't want to be wrestling with that gorilla!!!

Hwy # 9 runs sometimes less than a mile from the Mexican boarder here in New Mexico (NM). The US Border Patrol has many different types of detection equipment in place to monitor movement across our border with Mexico. It extends from Texas, through New Mexico, to California.

We have aerostat dirigibles, SSW of Deming, NM. Another near Sierra Vista, AZ and possibly more toward California that I’m unaware of.

The US Border Patrol also uses infrared, vibration, microwave, (for distances to two hundred yards that produce a volumetric pattern to detect a “disturbance in the force, Luke.)

All these little gizmo's are hooked to transmitters that more than likely are received at dispatch since on the scanner I can hear, “Agent Hernandez we have a hit in zone 3B, over!”

Now that our tax money has put these detection transmitters out for us I’m sure they must get a lot of false positives due to thermal disturbance.

How about a new application for our I-phones that puts a map up to the next several thermals starting up at ground level along our flight path?

We have heard of air moving and building up to a flash of lightning. Maybe
we should have designed instruments to detect static charge build up.
I remember my CB radio picking up static as the air passed over my
dry sailcloth. I was able to reduce the static with copper split bolts and
copper wire to ground all of my glider’s structural cables. Also wet sailcloth
Completely stopped the static picked up on the AM CB radio.
Perhaps thermals produce static electricity.

I know that the hot air from the burner in my balloon would create a high voltage static charge in the envelope. I had to insulate the pipe on my hand burner, used during inflation, to avoid getting big shocks from it. Using a grounding rod I could draw 1/2 inch sparks from the pipe. Scary when you know that there is propane right there.

The wire cable running from the top of the balloon to my electronic temperature meter had to have an excess voltage clamp to avoid blowing out the circuits from the static charge coming down from the top of the envelope.

Must have gotten the hair to stand up, Frank, being next to electricity and propane.
A tornado or low pressure, seems to have electrical energy rising, and going back down a nearby high pressure zone. interesting. The atmosphere is crazy 'bitchen'.
Question: could the temperature and electrical charge on the ground, help find 'thermals'?
