Scale of cloud cover measured in oktas (eighths) with the meteorological symbol for each okta. In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station.
Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 2 kilometres (6,600 ft) [10] from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere.
The luminance or brightness of a cloud is determined by how light is reflected, scattered, and transmitted by the cloud's particles. Its brightness may also be affected by the presence of haze or photometeors such as halos and rainbows. [114] In the troposphere, dense, deep clouds exhibit a high reflectance (70–95%) throughout the visible ...
Low, ragged clouds that appear beneath the main cloud base. Formed from moist air lifted by outflow winds from a storm. Often mistaken for tornadoes, but they are typically harmless, indicating ...
The constellation mural at Grand Central Terminal in New York City is an example of skyscape art. Skyscape art depicts representations of the sky, especially in a painting or photograph. Skyscapes differ from cloudscapes because they do not necessarily include clouds. Like cloudscape art, skyscape art can also omit any view of land or anything ...
A cloudscape painting by Jacob Isaakszoon van Ruisdael. In art, a cloudscape is the depiction of a view of clouds or the sky.Usually, as in the examples seen here, the clouds are depicted as viewed from the earth, often including just enough of a landscape to suggest scale, orientation, weather conditions, and distance (through the application of the technique of aerial perspective).
The yellow color is due to the presence of pollutants in the smoke. Yellowish clouds caused by the presence of nitrogen dioxide are sometimes seen in urban areas with high air pollution levels. [22] Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere.
However, the cloud sheet is not completely uniform, so that separate cloud bases still can be seen. This is the main precipitating type, however any rain is usually light. If the cloud layer becomes grayer to the point when individual clouds cannot be distinguished, stratocumulus turn into stratus clouds.
