| Caption | A multi-tiered shelf cloud, marking the leading edge of strong wind flowing out of a thunderstorm, looms over houses southwest of Gainesville, Florida, on the afternoon of August 1, 2009. A shelf cloud, also known as an arcus cloud, forms when cold, dense air from a thunderstorm's downdraft flows underneath and lifts warm, moist air surrounding the storm. | |
