take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps

sounds like you have a pad rubbing on a disk/rotor, if you jolt the brakes does the noise go away? if so it's probably a pad loose

More often than not the power steering fluid is low and that is the whine that you hear. Fill up your power steering fluid and see if it goes away. Cost about $5 bucks and will tell you if you need to spend more $$$ on something else.

I have a few suggestions for you,
First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.
I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.
Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.
You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?
Hope I've helped, and don't forget to rate.

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.
