There are (at least) two ways to approach this:
- Find an appropriate recording to use as a starting point
- Record your own wind and use that as a starting point
Either way, you're going to need to do some experimenting to get the sound you're after.
The first tool I'd reach for to create a "whipping" sensation would be either an amplitude modulator (think MondoMod) or a chain of dopplers (GRM or Waves), or the two of those working together. The key is create the feeling of motion through level variations, panning and pitch. Those two techniques will take you part of the way. Start with extreme settings and dial down from there.
Layering would be next for me. Either laying something unique on top or varispeeding what you've already chosen, this will bring broader frequency range to your sound. Whatever you choose, be sure to run this new layer through the same plugin chain so your modulations match (unless that's not what you're going for; maybe the low bluster has a slower modulation than the high whistle).
Another thing to try would be choosing an unrelated sound that has modulation you like and using that as a side-chain key to trigger your source wind. Example: You have a wind sound with good character but no dynamics. You also have a fantasy vortex sound with tons of movement but is too sci-fi. Simply insert a gate on your wind track, set the side-chain key as the vortex track, and let the vortex modulate your wind. (You could also do this with a convolution reverb, using the vortex as an IR and running the wind through it at various levels of wet/dry. You will also reap pitch variations using this technique.)
Anyhow, a few suggestions!
