From the ground, it just looks cloudy. But as you go up in an airplane, you see the makeup of the atmosphere is much more complex, with several layers of clouds making up the overcast we see from our backyard. If you know how to read the Skew-T weather map, you can figure out exactly how high those clouds are, layer by layer!

I just heard my friends at Good Morning America say, "It's 4 below zero outside ... with the wind chill."

We've heard about the Wind Chill Factor since we were kids, but what exactly is it? Here's a look at the new and improved wind chill chart and formula.

Here are the differences between high pressure vs low pressure in the world of weather.
