APOD: A Roll Cloud Over Uruguay (2013 Jun 02) Credit & Licence: Daniela Mirner Eberl http://apod.nasa.gov/apod/ap130602.html Explanation: What kind of cloud is this? A roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud, a type of Arcus cloud, is completely detached from their parent cumulonimbus cloud. Pictured above, a roll cloud extends far into the distance in 2009 January above Las Olas Beach in Maldonado, Uruguay. http://commons.wikimedia.org/wiki/File:Roll-cloud.JPG Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130602 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0602
