Chlamydomonas nivalis. Chlamydomonas nivalis, also referred to as Chloromonas typhlos, [ 2][ 1] is a unicellular red-coloured photosynthetic green alga that is found in the snowfields of the alps and polar regions all over the world. They are one of the main algae responsible for causing the phenomenon of watermelon snow (also blood snow ...
Snow hydrologists focus specifically on movement and composition of snow and ice, within the field of hydrology. The knowledge gained from this career is most commonly used in weather forecasting and ecological/ agricultural jobs, which require knowledge about the effects of snow migration. They retrieve the information they need through depth ...
Snice. Snice is a portmanteau of snow and ice.It refers to a type of frozen water whose physical characteristics make it an intermediate between snow and ice: snow-ice. The use of snice has become normative in modern ice construction, in buildings such as the winter ice hotels constructed annually in certain arctic nations, and the elaborate ice palace constructions, where it forms the bonding ...
Watermelon snow, also called snow algae, pink snow, red snow, or blood snow, is a phenomenon caused by Chlamydomonas nivalis, a species of green algae containing a secondary red carotenoid pigment ( astaxanthin) in addition to chlorophyll. Unlike most species of fresh-water algae, this species appears to be cryophilic (cold-loving) and thrives ...
Noise (video) Noise in a CRT television (top) and flat screen television (bottom) Noise, static or snow screen captured from a VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna ...
The November 13–21, 2014 North American winter storm (given the code name Knife by local governments [4] [5] and colloquially nicknamed Snovember [6]) was a potent winter storm and particularly severe lake-effect snowstorm that affected the United States, originating from the Pacific Northwest on November 13, which brought copious amounts of lake-effect snow to the Central US and New England ...
Snow can be classified by describing the weather event that is producing it, the shape of its ice crystals or flakes, how it collects on the ground, and thereafter how it changes form and composition. Depending on the status of the snow in the air or on the ground, a different classification applies.
Snowflake. A snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, which falls through the Earth's atmosphere as snow. [ 1][ 2][ 3] Each flake nucleates around a tiny particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form.
