So, i recorded sound of wind blowing using my mic. Yeah its not really wind since it was me who was blowing the air to make this sound but it sounds similar. Feel free to use it :).
Simulation of blowing wind created by mouthing wind sounds into the mic, then processing with large-room reverb. Recorded with a rode nt1a condenser mic.
Strong winds blowing across the river dee estuary marshes. Recorded at little neston using an h4n and shotgun microphone in a rycote cyclone wind-shield. The cry of sea birds can be heard over the sound of the wind now and again.
