It generally form as rime or mixed icing and tends to be confined in a 3,000–4,000 ft (910–1,200 m) thick layer. In contrast, icing intensity level in cumuliform clouds may range from trace for small cumulus to severe for large ones in the form of clear or mixed icing in the upper levels and can extend to great heights.

Icing on UAVs is a global phenomenon, and icing conditions at the operational altitude can occur year round around the world. However, icing risks are particularly big in the sub arctics, Arctic and Antarctic. In large parts of the Nordics, for example, icing conditions are present from 35% to more than 80% of the time from September through ...
A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.
Significant icing, featuring a build up of 0.25 of an inch or more, can occur into Wednesday night mainly along and between the Interstates 70 and 80 corridors in Michigan, Indiana and Ohio.
The Weather Channel 18 minutes ago Dual Winter Storms To Blanket Plains, Midwest And Northeast With Snow And Ice This Week. New week, more snow and ice for the Northeast, Midwest and Plains.
The weather conditions required for flight under VFR are known as visual meteorological conditions (VMC). The boundary criteria between VMC and IMC are known as VMC minima. IMC and VMC are mutually exclusive. In fact, instrument meteorological conditions are defined as less than the minima specified for visual meteorological conditions. [1]
Under some specific atmospheric conditions, forming and descending snow crystals may encounter and pass via atmospheric supercooled cloud droplets. These droplets, which have a diameter of about 10 μm, can exist in an unfrozen state down to temperatures near −40 °C (−40 °F).
The National Weather Service said temperatures in the city of Bismarck reached negative 35 degrees this week, breaking a 150 year-old record. Record low temperatures were also recorded in ...
