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?

The vapor pressure of pure CH2Cl2 (with molecular weight 85 g/mol) is 133 torr at 0˚C and the vapor pressure of pure CH2Br2 (with molecular weight 174 g/mol) is 11 torr at the same temperature.
What is the total vapor pressure at 0˚C of a solution prepared from equal masses of these two substances?
