My 99 RS does the same thing, but I let it warm up for 10 min in the morning then its gone! Annoying but i dont think there is anything I can do about it, just let it warm up!

Sure the belts are tight? Or maybe the idler pulley is going.

I know that our army 2 1/2 ton trucks have that whiz when they are cold, it is just the turbo. Maybe it's the turbo on your car, could be bearings or oil starvation, try to pin point the noise

Check the harmonic balancer.
