Horizontal rolls over southern Georgia on Jan. 20, 2013

Each week we are inundated with terrific photos and video from our iWitness Weather contributors both in the United States and abroad.

(SEND US YOUR PHOTOS:  WunderPhotos)

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.

Being a father is very hard! I know, I sound like a whiner, but I felt especially bad this week when I caused my daughter to miss the lunar eclipse.

California Drought/Polar Vortex Jet Stream Pattern Linked to Global Warming

By Dr. Jeff Masters
April 16, 2014

From November 2013 - January 2014, a remarkably extreme jet stream pattern set up over North America, bringing the infamous "Polar Vortex" of cold air to the Midwest and Eastern U.S., and a "Ridiculously Resilient Ridge" of high pressure over California, which brought the worst winter drought conditions ever recorded to that state. A new study by Utah State scientist S.-Y. Simon Wang found that this jet stream pattern was the most extreme on record, and likely could not have grown so extreme without the influence of human-caused global warming.

Preliminary data from NASA indicates that globally (land-ocean temperature index), it was the 4th warmest March on record (since 1880).

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
