The common phrase "red sky at morning" is a line from an ancient rhyme often repeated with variants by mariners [1] and others: Red sky at night, sailors' delight. Red sky at morning, sailors take warning.
When weather systems predominantly move from west to east, a red sky at night indicates that the high pressure air (and better weather) is westwards. In the morning the light is eastwards, and so a red sky then indicates the high pressure (and better weather) has already passed, and an area of low pressure is following behind. [11] A red sunrise.
Sailors are taught if the sunrise is red to take warning. The day ahead will be dangerous. "Red Sky at night, Sailors delight; Red Sky in the morning, Sailor's take warning." It may also be said as; "Red at morning, Sailors warning; Red at night, Sailors delight," or "Red sky at night, Sailor's delight; Red sky at morn, Sailor be warned."
Noctilucent clouds (NLCs), or night shining clouds, [1] are tenuous cloud-like phenomena in the upper atmosphere of Earth. When viewed from space, they are called polar mesospheric clouds (PMCs) , detectable as a diffuse scattering layer of water ice crystals near the summer polar mesopause .
Clouds and potentially fog can form within a marine layer when the water-saturated air is cooled and reaches a humidity of 100%, where it will then condense and turn into water droplets. [3] Stratus and stratocumulus can form at the top of a marine layer in the presence of these conditions. A marine layer can often be dispersed by sufficiently ...
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.
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.
Pressure systems cause weather to be experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and ...
