Dulan County
Dulan County ( Mongolian:; ; ) is a county of east-central Qinghai province, China. It is under the administration of Haixi Mongol and Tibetan Autonomous Prefecture. Climate With an elevation of around , Dulan County has a subalpine semi-arid climate (Köppen ''BSk''), with long, very cold and winters, and warm summers. Average low temperatures are below freezing from early/mid October to mid/late April; however, due to the wide diurnal temperature variation, only December and January have an average high that is below freezing. With monthly percent possible sunshine ranging from 60% in July to 81% in November, the county seat is very sunny, receiving 3,092 hours of bright sunshine annually; relative humidity in all months is below 50% and is for seven months below 40%. The monthly 24-hour average temperature ranges from in January to in July, while the annual mean is . Over 70% of the annual precipitation of is delivered from May to August.

Postal Code Of China
Postal codes in the People's Republic of China () are postal codes used by China Post for the delivery of letters and goods within mainland China. China Post uses a six-digit all-numerical system with four tiers: the first tier, composed of the first two digits, show the province, province-equivalent municipality, or autonomous region; the second tier, composed of the third digit, shows the postal zone within the province, municipality or autonomous region; the fourth digit serves as the third tier, which shows the postal office within prefectures or prefecture-level cities; the last two digits are the fourth tier, which indicates the specific mailing area for delivery. The range 000000–009999 was originally marked for Taiwan (The Republic of China) but is not used because it not under the control of the People's Republic of China. Mail to ROC is treated as international mail, and uses postal codes set forth by Chunghwa Post. Codes starting from 999 are the internal codes use ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

China National Highway 109
China National Highway 109 connects Beijing with Lhasa. It runs westwards from Beijing via Datong, Yinchuan and Xining to Golmud before turning southwest to Lhasa. The portion of the highway from Xining to Lhasa is known as the Qinghai-Tibet Highway. The total length of the route is 3,901 km. Fushi Road or Jinglan Road forms the stretch of G109 in Beijing, as it begins from Fuchengmen and traverses through Shijingshan. The majority of the Beijing section is in Mentougou District. The section of the highway within western Qinghai and Tibet, from Golmud to Lhasa, is paralleled by the Qinghai-Tibet Railway. The highway reaches its highest elevation of at Tanggula Pass. Construction of this section started on 11 May 1954. "Tasked with carrying upwards of 85 per cent of goods in and out of Tibet, the Qinghai-Tibet Highway has been dubbed the "Lifeline of Tibet." ... Since it was opened to traffic in 1954, the central government has spent nearly 3 billion yuan (US$362 millio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reshui Township
Reshui Township () is a township in Dulan County, Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai, western China. It is located at the base of the Jingpeng Pass at approximately {{convert, 3300, m altitude in the Tibetan Plateau. The name of the township literally means "hot water", which may refer to the hot springs in the area. Reshui is located on the 943 km long Jitong Railway, which was officially connected to National network and fully operative on 12 January 1995. The railway runs from Benhong (0 km)to Zhelimu (943 km). Reshui Town is close to Galadesitai railway station, located at 517 km. This railway was operated by QJ steam engines operating in tandem until Autumn 2005. The railway has many spectacular features, particularly viaducts, and is now dieselised. Reshui is in a development phase with many new buildings from 2004 and a new road by pass. There are several raided burial tombs in a necropolis in Reshui.

China Meteorological Administration
The China Meteorological Administration (CMA) is the national weather service of the People's Republic of China. The institution is located in Beijing. History The agency was originally established in December 1949 as the Central Military Commission Meteorological Bureau. It replaced the Central Weather Bureau formed in 1941. In 1994, the CMA was transformed from a subordinate governmental body into one of the public service agencies under the State Council.CMA.gov history Meteorological bureaus are established in 31 , |
Relative Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag is an important factor in diurnal temperature variation: peak daily temperature generally occurs ''after'' noon, as air keeps net absorbing heat even after noon, and similarly minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground to waist height. Incoming solar radiation exceeds outgoing heat energy for many hours afte ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subalpine
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in ...

County (People's Republic Of China)
Counties ( zh, t=縣, s=县, hp=Xiàn), formally county-level divisions, are found in the third level of the administrative hierarchy in Provinces and Autonomous regions and the second level in municipalities and Hainan, a level that is known as "county level" and also contains autonomous counties, county-level cities, banners, autonomous banners and City districts. There are 1,355 counties in Mainland China out of a total of 2,851 county-level divisions. The term ''xian'' is sometimes translated as "district" or "prefecture" when put in the context of Chinese history. History ''Xian'' have existed since the Warring States period and were set up nationwide by the Qin Dynasty. The number of counties in China proper gradually increased from dynasty to dynasty. As Qin Shi Huang reorganized the counties after his unification, there were about 1,000. Under the Eastern Han Dynasty, the number of counties increased to above 1,000. About 1400 existed when the Sui dynasty abolish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolian Language
Mongolian is the official language of Mongolia and both the most widely spoken and best-known member of the Mongolic language family. The number of speakers across all its dialects may be 5.2 million, including the vast majority of the residents of Mongolia and many of the ethnic Mongol residents of the Inner Mongolia Autonomous Region of the People's Republic of China.Estimate from Svantesson ''et al.'' (2005): 141. In Mongolia, Khalkha Mongolian is predominant, and is currently written in both Cyrillic and traditional Mongolian script. In Inner Mongolia, the language is dialectally more diverse and is written in the traditional Mongolian script. However, Mongols in both countries often use the Latin script for convenience on the Internet. In the discussion of grammar to follow, the variety of Mongolian treated is the standard written Khalkha formalized in the writing conventions and in grammar as taught in schools, but much of what is to be said is also valid for vernacular ...

China Standard Time
The time in China follows a single standard time offset of UTC+08:00 (eight hours ahead of Coordinated Universal Time), even though the country spans almost five geographical time zones. The official national standard time is called ''Beijing Time'' (BJT, ) domestically and ''China Standard Time'' (CST) internationally. Daylight saving time has not been observed since 1991. China Standard Time (UTC+8) is consistent across Mainland China, Hong Kong, Macau, Taiwan, Philippines, Singapore, Brunei, Mongolia, etc. History In the 1870s, the Shanghai Xujiahui Observatory was constructed by a French Catholic missionary. In 1880s officials in Shanghai French Concession started to provide a time announcement service using the Shanghai Mean Solar Time provided by the aforementioned observatory for ships into and out of Shanghai. By the end of 19th century, the time standard provided by the observatory had been switched to GMT+08:00. The practice has spread to other coastal ports, and in ...
