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.
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."
Above the ocean or a large lake, air is typically more humid than above land. When the humid air moves over cold land, it will form fog and precipitation. (To the east of the North American Great Lakes , this is a common phenomenon, and is known as the " lake effect .") [ 17 ] In northerly climates, ice fog may form when the temperature drops ...
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 ...
A mill cannot grind with the water that is past; A miss is as good as a mile; A new language is a new life (Persian proverb) [5] A penny saved is a penny earned; A picture is worth a thousand words; A rising tide lifts all boats; A rolling stone gathers no moss; A ship in a harbour is safe, but that's not what a ship is for; A stitch in time ...
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.
Earth's rotation relative to the Sun causes the 24-hour day/night cycle. A diurnal cycle (or diel cycle) is any pattern that recurs every 24 hours as a result of one full rotation of the planet Earth around its axis. [1] Earth's rotation causes surface temperature fluctuations throughout the day and night, as well as weather changes throughout ...
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 ...
