Circumhorizontal Arc (Fire Rainbow) In The Nepal Himalayas
A circumhorizontal arc is an optical phenomenon that belongs to the family of ice halos formed by the refraction of sunlight or moonlight in plate-shaped ice crystals suspended in the atmosphere, typically in cirrus or cirrostratus clouds. In its full form, the arc has the appearance of a large, brightly spectrum-coloured band (red being the topmost colour) running parallel to the horizon, located far below the Sun or Moon. The distance between the arc and the Sun or Moon is twice as far as the common 22-degree halo. Often, when the halo-forming cloud is small or patchy, only fragments of the arc are seen. As with all halos, it can be caused by the Sun as well as (but much more rarely) the Moon. Other currently accepted names for the circumhorizontal arc are circumhorizon arc or lower symmetric 46° plate arc. The misleading term "fire rainbow" is sometimes used to describe this phenomenon, although it is neither a rainbow, nor related in any way to fire. The term, apparently c ...

Perspective Distortion (photography)
In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features. Perspective distortion is determined by the relative distances at which the image is captured and viewed, and is due to the angle of view of the image (as captured) being either wider or narrower than the angle of view at which the image is viewed, hence the apparent relative distances differing from what is expected. Related to this concept is axial magnification -- the perceived depth of objects at a given magnification. Perspective distortion takes two forms: ''extension distortion'' and ''compression distortion,'' also called ''wide-angle distortion'' and ''long-lens'' or ''telephoto distortion,'' when talking about images with the same field size. Extension or wide-angle distortion can be seen in imag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumzenithal Arc
The circumzenithal arc, also called the circumzenith arc (CZA), upside-down rainbow, and the Bravais arc,"Mémoire sur les halos et les phénomènes optiques qui les accompagnent", J. de l' École Royale Polytechnique 31(18), 1-270, A. Bravais, 1847 is an optical phenomenon similar in appearance to a rainbow, but belonging to the family of halos arising from refraction of sunlight through ice crystals, generally in cirrus or cirrostratus clouds, rather than from raindrops. The arc is located at a considerable distance (approximately 46°) above the observed Sun and at most forms a quarter of a circle centered on the zenith. It has been called "a smile in the sky", its first impression being that of an upside-down rainbow. The CZA is one of the brightest and most colorful members of the halo family. Its colors, ranging from violet on top to red at the bottom, are purer than those of a rainbow because there is much less overlap in their formation. The intensity distribution along ...

Cloud Iridescence
Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface. It is a type of photometeor. This fairly common phenomenon is most often observed in altocumulus, cirrocumulus, lenticular, and cirrus clouds. They sometimes appear as bands parallel to the edge of the clouds. Iridescence is also seen in the much rarer polar stratospheric clouds, also called nacreous clouds. The colors are usually pastel, but can be very vivid or mingled together, sometimes similar to mother-of-pearl. When appearing near the Sun, the effect can be difficult to spot as it is drowned in the Sun's glare. This may be overcome by shielding the sunlight with one's hand or hiding it behind a tree or building. Other aids are dark glasses, or observing the sky reflected in a convex mirror or in a pool of water. Etymology Irisations are named after t ...

Sundogs
A sun dog (or sundog) or mock sun, also called a parhelion (plural parhelia) in meteorology, is an atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Sun. Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun. They can be seen anywhere in the world during any season, but are not always obvious or bright. Sun dogs are best seen and most conspicuous when the Sun is near the horizon. Formation and characteristics Sun dogs are commonly caused by the refraction and scattering of light from horizontally oriented plate-shaped hexagonal ice crystals either suspended in high and cold cirrus or cirrostratus clouds, or drifting in freezing moist air at low ...

Silang, Cavite
Silang, officially the Municipality of Silang ( tgl, Bayan ng Silang), is a 1st class municipality in the province of Cavite, Philippines. According to the 2020 census, it has a population of 295,644 people. Silang is located in the eastern section of Cavite.

With the continuous expansion of Metro Manila, the municipality is now part of the Manila's conurbation which spans southward toward Lipa City. History Pre-Hispanic period The traditional origins of the town are attributed to ten Bornean datus who sailed northward on board balangays and ended in Silang through Taal Lake. Its first settlers were Gat Hingiw, his wife Gat Kaliwanag, and their seven children, who later moved to different parts of the town and established their respective barangays. Gat Pandan stayed in the original community and developed the area. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrightsville, Pennsylvania
Wrightsville is a borough in York County, Pennsylvania, United States. The population was 2,257 at the 2020 census. Wrightsville borough has a police department, historic society, and a volunteer fire company. History According to a plaque at Samuel S. Lewis State Park, which overlooks Wrightsville and the Susquehanna River, Wrightsville was among George Washington's choices as the location of the capital of the United States. The world's longest covered bridge, at , once spanned the Susquehanna from Wrightsville to neighboring Columbia in Lancaster County. Built in 1814, it was destroyed by high water and ice in 1832. A replacement bridge was burned the night of June 28, 1863, by state militia during the Gettysburg Campaign in the American Civil War. Confederate troops under John Brown Gordon formed a bucket brigade to save the town from fire. Yet another replacement covered bridge was destroyed by a windstorm a few years later. The final bridge, the Pennsylvania Railro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emerald Isle, North Carolina
Emerald Isle is a town in Carteret County, North Carolina, United States. It is part of the Crystal Coast and is located entirely on Bogue Banks. The population was 3,655 at the 2010 census, but as many as 50,000 tourists each week inhabit the area during the summer season, filling up vacant rental properties that do not count toward official census results. Today, the oceanfront is lined with large and small homes, duplexes, condominiums, and one oceanfront hotel. Emerald Isle has a family-oriented atmosphere. Recent beach renourishment projects in North Carolina, including Emerald Isle, have been both praised and questioned. History From about 1 AD to colonial times, Emerald Isle was home to Native Americans. Later, the area was settled by a small number of whalers and fishermen. In the 1920s Henry Fort, who owned the Emerald Isle beaches and land surrounding them, hoped to open a large summer tourist attraction and ocean resort. Fort worked with developers, but the plans ...

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population.
