As happened last year in the frigid months of a midwest winter, my 03' Ford Explorer has started to make an ear piercing whistle coming from the hood. The whistle appears to be happening at transition points at or about every 10 mph (i.e noticeable at 30mph through 70 mph) - lasting until I accelrate to ~32, 42.... 72 mph, etc. This ONLY occurs on days when the ambient air temperature is below freezing. Wondering if it is an air intake issue, or something else.

sounds to me like idol control sensor is being temperamental.Its not uncommon to happen.It is basically sticking and when you are accelerating it isn't opening up quite all the way and therefore makes this whistling noise.
This is a control valve for emissions system and helps recirculate the air in the air intake unit to make the car burn the fuel more efficiently and give it proper air to fuel mixture for better gas mileage and to make the car run cleaner.
I am sure you notice that the car seems to burn more fuel on days when it is cooler as well?
Take it to a mechanic when it is acting up and have him plug it in to the computer do diagnose this.

could be just that with the engine hot, and you parked outside..the power steering belt (which was hot) from the engine, built up a condensation on the belt and when you crank it. the belt is slipping and causing a high pitch noise, and after the engine builds operating temperture, the belt is unfrozen and doesn't skip anymore... we don't have this problem in ALABAMA, but the symptoms are the same if you have a loose belt, or one with fuild on it..but then again it could be the compressor belt, it you have the defrost on

correct the position you left it...on the Nolte's evening stand. Come on over any time to retrieve it, cutie ;) Edit: sounds like a plan, toddler....and they say you won't be able to locate Heaven on earth. good day, The Nolte basically revealed a question asking about you the different day. for sure, it met its death interior hours...you've been neglected through many, you throbbing hunk of masculinity.
