How to make a wind effect?

[Melvin]

Hey FrictionalGames Forum,

I want to know how to make this scenario:

You walk into a room, and suddenly you hear wind whistling through your ears, and you see wind flowing towards you.

I know how to trigger the sound. (PlaySoundAtEntity etc.)
I know how to set up an area.

My main question here: In which catagory do I find the wind effects? (like in the first Amnesia level when a door is blown open by the wind) is it in the particles? If yes, how do I trigger a particle if the player colides with an area?

Thanks guys!
