ice crystals

The second weekend in April produced a wintry potpourri of weather across the Front Range, including an eye-catching array of ice crystals on trees around the Mesa Lab. Tom Wigley (ESSL/CGD) photographed these spiky clusters of crystals attached to pine trees on April 8. Each of the crystals was about 2 inches long, Tom reports, and they grew without congealing around individual pine needles. The rimed crystals likely developed in a moist, supercooled fog (fog containing water droplets in liquid form that exist at temperatures colder than 32 degrees Fahrenheit) with very calm conditions.
