Duplicate Sandstorm and change direction?

I'm working on a level where the player sky dives out of a exploding spaceship. I'm using a few tricks to fool the player and create a sense of free falling. One idea I had was to use the vanilla sandstorm (precipitation thing) spread out and really thin to simulate debris flying past the player, but I need the sandstorm's direction to be going upwards, is there a simple way to do this?

Any ideas?
