Hyperarid
An aridity index (AI) is a numerical indicator of the degree of dryness of the climate at a given location. A number of aridity indices have been proposed (see below); these indicators serve to identify, locate or delimit regions that suffer from a deficit of available water, a condition that can severely affect the effective use of the land for such activities as agriculture or stock-farming. Historical background and indices Köppen At the turn of the 20th century, Wladimir Köppen and Rudolf Geiger developed the concept of a climate classification where arid regions were defined as those places where the annual rainfall accumulation (in centimetres) is less than R/2, where: * R=2\times T if rainfall occurs mainly in the cold season, * R=2\times T+14 if rainfall is evenly distributed throughout the year, and * R=2\times T+28 if rainfall occurs mainly in the hot season. where T is the mean annual temperature in Celsius. This was one of the first attempts at defining an arid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanization Of Chinese
Romanization of Chinese () is the use of the Latin alphabet to transliterate Chinese. Chinese uses a logographic script and its characters do not represent phonemes directly. There have been many systems using Roman characters to represent Chinese throughout history. Linguist Daniel Kane wrote, "It used to be said that sinologists had to be like musicians, who might compose in one key and readily transcribe into other keys." The dominant international standard for Standard Mandarin since about 1982 has been Hanyu Pinyin, invented by a group of Chinese linguists in the 1950s including Zhou Youguang. Other well-known systems include Wade–Giles (Mandarin) and Yale Romanization (Mandarin and Cantonese). There are many uses for Chinese Romanization. Most broadly, it is used to provide a useful way for foreigners who are not skilled at recognizing Chinese script to read and recognize Chinese. It can also be helpful for clarifying pronunciation among Chinese speakers who speak mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

37° N
The 37th parallel north is a circle of latitude that is 37 degrees north of the Earth's equatorial plane. It crosses Europe, the Mediterranean Sea, Africa, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. At this latitude the Sun is visible for 14 hours, 42 minutes during the summer solstice and 9 hours, 37 minutes during the winter solstice. The 37th parallel north is roughly the northern limit of the visibility of Canopus, the second-brightest star of the night sky. Along with the 37th parallel south, it is the latitude at which solar irradiance is closest to the planetary average,See Nadeau, Alice and McGhee, Richard; ‘A simple formula for a planet's mean annual insolation by latitude’; ''Icarus'', volume 291, 15 July 2017, pp. 46-50 with higher solar irradiance equatorward and lower poleward.

The color (''qīng'') was a "single" color inclusive of both blue and green as separate shades. (English for ''qīng'' is cyan or turquoise, also linguists have coined the portmanteau "grue" to discuss its existence in Chinese and other languages.) The name is thus variously translated as "Blue Sea", "Green Sea", "Blue-Green Sea", "Blue/Green Sea", etc. For a time after ...
