An early cloudscape photographer, Belgian photographer Léonard Misonne (1870–1943), was noted for his black and white photographs of heavy skies and dark clouds. [ 1 ] In the early to middle 20th century, American photographer Alfred Stieglitz (1864–1946) created a series of photographs of clouds, called "equivalents" (1925–1931).
However, if such a storm is in the offing, it is not necessary to observe the cloud motions to know rain is a good possibility. The nature of airflows directly at a frontal boundary can also create conditions in which lower winds contradict the motions of upper clouds, and the passage of a frontal boundary is often marked by precipitation. Most ...
“Heavy hearts, like heavy clouds in the sky, are best relieved by the letting of a little water.” ― Christopher Morley “There is hope, even when your brain tells you there isn’t.”
“Try to be a rainbow in someone’s cloud.” “My wish for you is that you continue. Continue to be who and how you are, to astonish a mean world with your acts of kindness.”
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.
A stratocumulus cloud, occasionally called a cumulostratus, belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower height, usually below 2,000 metres (6,600 ft).
Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
