Today, and every Saturday Earth Science Picture of the Day invites you to rediscover favorites from the past. Saturday posts feature an EPOD that was chosen by viewers like you in our monthly Viewers' Choice polls. Join us as we look back at these intriguing and captivating images.
The panorama featured above shows a sinister-looking shelf cloud as it approached the town of Bad Mergentheim, in southern Germany on June 6, 2010. Shelf clouds are attached to the parent thunderstorm and are positioned at its leading edge. They typically form when cool air associated with a thunderstorm's downdraft advances into the warm, humid air feeding the storm. Though they generally don't presage the formation of tornadoes, their winds can at times be severe.
