Noctiluca scintillans is a marine species of dinoflagellate that can exist in a green or red form, depending on the pigmentation in its vacuoles.It can be found worldwide, but its geographical distribution varies depending on whether it is green or red.
When these high clouds progressively invade the sky and the barometric pressure begins to fall, precipitation associated with the disturbance is likely about 6 to 12 hours away. A thickening and lowering of cirrocumulus into middle-étage altostratus or altocumulus is a good sign that the warm front or low front has moved closer and it may ...
The clouds do not become that color; they are reflecting long and unscattered rays of sunlight, which are predominant at those hours. The effect is much like if a person were to shine a red spotlight on a white sheet. In combination with large, mature thunderheads this can produce blood-red clouds.
Noctilucent clouds form mostly near the polar regions, [8] because the mesosphere is coldest there. [15] Clouds in the southern hemisphere are about 1 km (3,300 ft) higher than those in the northern hemisphere. [8] Ultraviolet radiation from the Sun breaks water molecules apart, reducing the amount of water available to form noctilucent clouds.
Sea of fog riding the coastal marine layer through the Golden Gate Bridge at San Francisco, California Afternoon smog within a coastal marine layer in West Los Angeles. A marine layer is an air mass that develops over the surface of a large body of water, such as an ocean or large lake, in the presence of a temperature inversion.
A sea of clouds is an overcast layer of stratocumulus clouds, as viewed from above, with a relatively uniform top which shows undulations of very different lengths resembling waves on the sea. [1] A sea of fog is formed from stratus clouds or fog and does not show undulations. [2] In both cases, the phenomenon looks very similar to the open ocean.
The Met Office said lenticular clouds combined with the sunrise to create the stunning effect. The clouds tend to form "when air blows across a mountain range in certain circumstances" and when ...
Bluish flickers visible in ocean water at night often come from blooms of bioluminescent dinoflagellates, which emit short flashes of light when disturbed. Algal bloom (akasio) by Noctiluca spp. in Nagasaki. A red tide occurs because dinoflagellates are able to reproduce rapidly and copiously as a result of the abundant nutrients in the water.
