Though it's tough to narrow it down from the hundreds of entries, we've selected what we think are the five best weather photos or video of this past week.
We begin with this first photo above, taken on a flight over south Georgia on Jan. 20, 2013. What you see are "cloud streets", or "horizontal rolls", consisting of air rotating about a horizontal axis, i.e. parallel to the ground. These "cloud streets" are typically aligned with the direction of winds in the lowest levels of the atmosphere.
