Does wind an effect on Doppler shift?

Question

If both the sound source and the listener are stationary, but there is a significant wind in between them, will the tone of the sound be affected?

This question comes from my experience standing downwind from a monotonal tsunami warning siren (I've heard it under normal circumstances and it does not change pitch) and hearing it change pitch during some high winds. I was facing the siren and it seemed as though the pitch got higher as the wind blew towards me. Was I hearing a wind-induced Doppler shift?

Answer 1

Jeff,

My guess is that the wind has little effect on the frequency but that it may affect the magnitude or volume of the siren. Doppler shift is due to the movement of the "source" relative to the receiver. Now in a Doppler radar the situation is different because the receiver is also the transmitter and is looking at the shift in received radiation reflected from precipitation particles moving with the air.

Answer 2

....good question, never really thought about it.
hmmmmm...can the wind compress or expand a sound wave?...(still thinking...)
I would imagine the answer would be yes ergo a wind induced Doppler shift.
...but I'm really not sure.
Good Question. (gona look this one up!)

Answer 3

I see no way that the motion of the medium can affect the wave length of the sound.
