The Narin Gol River (), sometimes spelled Narin-Gol River, also known as Narenguole River, or Nalenggele River, is an inland river in Qinghai Province of China, located in the Qaidam Basin, with a length of 435 kilometres, a catchment area of about 21,898 square kilometers, and an average annual runoff volume of about 1.07 billion cubic metres. The river is the largest river in the Qaidam Basin, stemming from Bukedaban, the highest peak of East Kunlun. According to the Naren Gol Hydrological Station (那仁郭勒水文站), the runoff volume of Narin Gol River accounts for 59.6 per cent of the annual volume during the rich water period in summers, and 6 per cent of the annual volume during the dry water period in winter Winter is the coldest season of the year in polar and temperate climates.

Kilometres
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimet ...

Winter
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summer
Summer is the hottest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorological centre of the season, which is based on average temperature patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Another alternative name, no longer widely used, was the kilolitre. Conversions : A cubic metre of pure water at the temperature of maximum density (3.98 °C) and standard atmospheric pressure (101.325 kPa) has a mass of , or one tonne. At 0 °C, the freezing point of water, a cubic metre of water has slightly less mass, 999.972 kilograms. A cubic metre is sometimes abbreviat ...

Square Kilometers
Square kilometre ( International spelling as used by the International Bureau of Weights and Measures) or square kilometer (American spelling), symbol km2, is a multiple of the square metre, the SI unit of area or surface area. 1 km2 is equal to: * 1,000,000 square metres (m2) * 100 hectares (ha) It is also approximately equal to: * 0.3861 square miles * 247.1 acres Conversely: *1 m2 = 0.000001 (10−6) km2 *1 hectare = 0.01 (10−2) km2 *1 square mile = *1 acre = about The symbol "km2" means (km)2, square kilometre or kilometre squared and not k(m2), kilo–square metre. For example, 3 km2 is equal to = 3,000,000 m2, not 3,000 m2. Examples of areas of 1 square kilometre Topographical Map grids Topographical map grids are worked out in metres, with the grid lines being 1,000 metres apart. * 1:100,000 maps are divided into squares representing 1 km2, each square on the map being one square centimetre in area and representing 1 km2 on ...

Catchment Area
In human geography, a catchment area is the area from which a location, such as a city, service or institution, attracts a population that uses its services and economic opportunities. Catchment areas may be defined based on from where people are naturally drawn to a location (for example, labour catchment area) or as established by governments or organizations for the provision of services. Governments and community service organizations often define catchment areas for planning purposes and public safety such as ensuring universal access to services like fire departments, police departments, ambulance bases and hospitals. In business, a catchment area is used to describe the influence from which a retail location draws its customers. Airport catchment areas can inform efforts to estimate route profitability. Types of catchment areas Catchments can be defined relative to a location and based upon a number of factors, including distance, travel time, geographic boundaries or popul ...

CNKI
CNKI (China National Knowledge Infrastructure; ) is a private-owned publishing company in China since 2014. CNKI maintains high annual subscription fees due to its ''de facto'' monopoly status on journal search in China. Because its subscription fee raised sharply every year, many elite Chinese universities and research institutions, including the Chinese Academy of Sciences and Peking University, have stopped subscribing to CNKI. CNKI owns a system called "China Integrated Knowledge Resources System," including journals, doctoral dissertations, masters' theses, proceedings, newspapers, yearbooks, statistical yearbooks, e-books, patents and standards. In January 2013, CNKI became the second designated DOI agent in mainland China, after the Institute of Scientific and Technical Information of China under the Ministry of Science and Technology. In May 2022, the State Administration for Market Regulation of China launched an antitrust investigation into CNKI for anti-competitiv ...
