Indeed it is my business. I do record in a studio, as well as on location. I have ran audio for outdoor shows. I have recorded audio for several independant films. The first 2 years I was in school I worked as an engineer for a local live television broadcast. In short I am just as qualified as you are attempting to establish yourself as.
He did just run down there with a camera...I assume that it is the in camera microphone that does the recording, which should have picked up any wind hiss, not just several dull echoing thuds...
Wind is a high frequency sound. These thuds register in the bass frequency quite clearly, and disappear in the upper register. This is why I am assuming most of you are unable to hear it fully. Little pc speakers aren't going to reveal much.
As far as reproducing these sounds exactly...I openly challenge you to do so, and to prove that this is wind noise. Which you won't be able to do.
Maybe you should watch the video, and observe the audio and video analysis that it contains as well.
