Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
The island generates wave motion in the wind passing over it, creating regularly spaced orographic clouds. The wave crests raise and cool the air to form clouds, while the troughs remain too low for cloud formation. Note that while the wave motion is generated by orographic lift, it is not required. In other words, one cloud often forms at the ...
With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.
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.
That wave cloud pattern formed over the Île Amsterdam, in the lower left corner at the tip of the triangular formation, in the far southern Indian Ocean. A wave cloud is a cloud form created by atmospheric internal waves. Wave cloud pattern in Tadrart region. Unusual wave clouds over the Aral Sea, seen from NASA's Water satellite on March 12 ...
Sea of clouds in Mount Pulag, Philippines. 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]
The wind flows towards a mountain and produces a first oscillation (A) followed by more waves. The following waves will have lower amplitude because of the natural damping. Lenticular clouds stuck on top of the flow (A) and (B) will appear immobile despite the strong wind. Lenticular clouds. In meteorology, lee waves are atmospheric stationary ...
Another way fog forms in deserts occurs when a desert is close to an ocean which has a cold current. When air is heated over desert land and blows towards the cool water in the ocean, it condenses and fog is formed. The cool fog is then blown inland by the ocean breeze. Fog is mainly formed in the early morning or after sunset. [5]
