Can You Guess the City Rising Above the Clouds?

It's an awe-inspiring sight any time an entire large city is shrouded by fog, especially when we can get photos from above. In the gallery at the top of this page, we have selected several of our favorites from the past few years.

There are several types of fog, but radiation fog is most common in the fall months, giving us more opportunities for spectacular images like the ones above.

"The most common form of fog, known as radiation fog, typically occurs on clear nights as the earth's surface cools moist air immediately above it," said weather.com meteorologist Jon Erdman. "If just enough light wind is present – a couple of mph, at most –  this chilled air can be gently stirred through a deeper layer, forming a deeper radiation fog."

The fog may be beautiful from above, but it can be dangerous for drivers attempting to navigate roadways when visibilities plummet. According to the Federal Highway Administration, more than 500 people are killed in crashes that are blamed on fog each year.

Check out the images above and see how many fog-covered cities you can identify.
