Every spring, Weatherwise's inbox is filled with spectacular photographs of meteorological events sent in by readers around the country. Entries range from beautiful atmospheric phenomena such as the Aurora Borealis, to quintessential seasonal images such as ice floes, to dramatic storms such as tornadoes. This year, the cloud has taken center stage among the winners of the contest. Our Grand Prize winner is one of the most spectacular examples of mammatus clouds the judges have ever seen. The Grand Prize winner is followed closely by a the First Prize winner, which is a pair of photographs of a lenticular cloud above Mount Rainier in Washington state. The photographs, taken hours apart, provide a stark contrast between day and night with the common thread of the cloud tying the two together. Supercells, wall clouds, cirrus fall streaks, hole clouds, and unusual fog formations make up just some of the other winning cloud photographs this year. Congratulations to these and all of our winners!
