High-pitched whine when cold, sometimes when warm V70-XC70 1998

I hear a high-pitched whine in my 1998 V70 AWD w/ 158K miles when the engine is cold. It lasts about a minute (it does not get louder with acceleration), and then generally stops. Sometimes it will do it again at idle (stoplights, traffic, etc.). I am wondering if it might be the air pump--for some reason, I seem to remember having read something about air pumps causing high-pitched whines. If so, does it need replacement? What does the air pump actually do, anyway?

Thanks
