However, with snowballs, the rolling stops once the snowball gets too heavy, meaning it stays wherever it stops. National Weather Service A sun dog (or sundog) or mock sun, also called a parhelion[1] (plural parhelia) in meteorology, is an atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Sun. Light pillars occur when natural or artificial light reflects off flat ice crystals in the air close to the Earths surface. Interestingly, these clouds are usually an indication that severe weather may be around. Check out the Farmers Almanac Weather Glossary for more unusual weather terms! The unusual weather phenomena on this list are strange because they are either extreme, meaning conditions need to be perfect for them to occur, or they are a bit of a mystery and have left researchers scratching their heads. However, people who have experienced these clouds have said that they give off the appearance that the sky is falling. Almanac Publishing Co. All Rights Reserved.

Please select one of the following: Regional/National Standard Radar (low bandwidth), National Oceanic and Atmospheric Administration. The colors overlap considerably and are muted, never pure or saturated. As the Sun rises higher, the rays passing through the plate crystals are increasingly skewed from the horizontal plane, causing their angle of deviation to increase and the sun dogs to move farther from the 22 halo, while staying at the same elevation. So, when light is refracted inside a an ice crystal or water droplet in the air, its broken into its component colors. A right-hand sun dog in Salem, Massachusetts, Oct 2012. and Swed. Anyone interested in weather and climate is welcome. Generally, these crystals, which have a hexagonal molecular structure, are found in the cirrus clouds.

In Norfolk a sun-dog is a light spot near the sun, and water-dogs are the light watery clouds; dog here is no doubt the same word as dag, dew or mist as "a little dag of rain" (Philolog. So, where do tornadoes come in? On a clear day, the sun heats the ground, and the ground in turn warms the air immediately above it. They are created by sunlight refracting off plate-shaped ice crystals in the cirrus clouds. This process of joining atoms together under immense pressure and temperature, forging new elements, is called fusion. It is still cold this Thursday, in particular with morning frosts present despite a slight rise in temperatures with a wind that is blowing less strongly than the previous days, according to the Weather Channel*. In addition to the shape of the ice crystals and the angle between the facets, the orientation of the ice crystals also determines the kind of optical phenomenon that will be created. Dust devils form in a very similar way to volcanic tornados, minus the volcano, of course. In Abram Palmer's 1882 book Folk-etymology: A Dictionary of Verbal Corruptions Or Words Perverted in Form Or Meaning, by False Derivation Or Mistaken Analogy, sun-dogs are defined: The phenomena [sic] of false suns which sometimes attend or dog the true when seen through the mist (parhelions). Sundogs tend to be most visible when the Sun is close to the horizon. The light is not separated into its component colors because it is not being "bent" (or refracted), and all wavelengths are being reflected at equal angles. Another halo variety often seen together with sun dogs is the 22 halo, which forms a ring at roughly the same angular distance from the sun as the sun dogs, thus appearing to interconnect them. Make your own self-watering system for your garden plants while you're on vacation. The shape and orientation of the ice crystals through which the light passes determines the type of halo you'll see.

It is believed that Catatumbo Lightning originates from storm clouds that float an impressive 16,000 feet (4,876 km) above the Earth. Its because of these properties that we get the various atmospheric optical effects. Even though the other two suns were not as bright as the one, they were clearly visible. The atmosphere does more than just produce our daily weather: from sunny to cloudy days, dry to wet, stormy to snowy. She lives in Western Massachusetts where she works at Orion magazine.". Dubbed Arctic Ocean Frost Flowers, this unusual weather phenomenon forms from imperfections on the ice's surface in sub-zero temperatures, usually around -20 celsius. Educational Resources A sun dog or sundog is a common bright circular (or symmetrical) spot on a solar halo. The dust devil, once formed, is a funnel-like chimney through which hot air moves both upward and circularly. Wind speeds in larger dust devils can reach 60 mph or greater. It is home to the Arizona State Sun Devils football team of the Pac-12 Conference. A halo is a ring or light that forms around the sun or moon as the sun or moon light refracts off ice crystals present in a thin veil of cirrus clouds.

Ice crystals can be found high up in the sky all around the world, at any time of the year. NWS Learn more about different kinds of twilight, dawn and dusk. This is a formation of cirrocumulus or altocumulus clouds that look like the pattern of scales on a mackerels back. Sailors used to say: Mackerel sky, mackerel sky. They are located approximately 22 degrees either left, right, or both, from the sun, depending on where the ice crystals are present. Sundogs are colored spots of light that develop due to the refraction of light through ice crystals. Inside this circle a half-circle appeared, similar to a rainbow, distinct in its fourfold color, in the higher part curved towards the two aforementioned Suns, touching them in an embrace of the Sun. Dust devils form in areas of strong surface heating, usually at the interface between different surface types, such as asphalt and dirt, or even irrigated fields and dirt roads. Basketball Postgame.
