Cannonsburg Ski and Ride Area (January 23, 2013)
GRAND RAPIDS (WZZM) - Winter has finally arrived and with it, snow. WZZM 13 meteorologist Joe Kopecek answered some questions we heard from those sledding Thursday in Grand Rapids:
Q: Why does snow sometimes sound squeaky and scratchy?
A: Joe says it has to do with how cold it is: "The colder the air, typically the drier the snow, which means there's less water in between the ice crystals. So when there's less water and you step on them - you get this crunching - they're slamming together and they're not lubricated between the ice crystals."
Q: Why does it seem so quiet when the ground is covered with snow?
A: Joe says, "That's because the sound gets absorbed by the snow, the sound waves get absorbed by the snow rather than reflecting off them."
Q: Will we get more snow?
A: Yes, several inches could fall Friday.
