34-669: Sanjiang (Chinese: 三江 ; lit. 'three rivers') originally and typically refers to the Three Parallel Rivers of southwestern China: the Jinsha (upper Yangtze ), the Lancang (Mekong), and the Nu (Salween). It may also refer to: Three Parallel Rivers of Yunnan Protected Areas The protected areas extend over 15 core areas, totalling 939,441.4 ha, and buffer areas, totalling 758,977.8 ha across

68-424: A distinct four-season pattern, especially in the continental climate sector. Oceanic climates are created by the on-shore flow from the cool high latitude oceans to their west. This causes the climate to have mild summers and cool (but not cold) winters, and relative humidity and precipitation evenly distributed throughout the year. These climates are frequently cloudy and cool, and winters are milder than those in

102-809: A few highland areas of Tasmania , the Australian Alps and Southern Alps of New Zealand . This type of climate is even found in tropical areas such as the Papuan Highlands in Indonesia. Cfc is the categorization for this regime. Even in the middle of summer, temperatures exceeding 20°C (68 °F) are exceptional weather events in the most maritime of those locations impacted by this regime. In some parts of this climate, temperatures as high as 30°C (86°F) have been recorded on rare occasions, while temperatures as low as −15 °C (5 °F) have still been recorded on rare occasions. A cold variant of

136-421: A huge impact on the productivity of agriculture which is less common. Temperate regions have the majority of the world's population, which leads to large cities . There are a couple of factors why the climate of large city landscapes differs from the climate of rural areas. One factor is the strength of the absorption rate of buildings and asphalt, which is higher than that of natural land. The other large factor

170-434: A humid subtropical climate (most notably southeast China and North India ), there is an even sharper wet-dry season, called a monsoon subtropical climate or subtropical monsoon (Cwa). In these regions, winters are quite chilly and dry and summers have very heavy rainfall. Some Cwa areas in southern China report more than 80% of annual precipitation in the five warmest months (southwest monsoon). Mediterranean climates have

204-534: A landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C , when the mean temperature is above −3 °C (26.6 °F) but below 18 °C (64.4 °F) in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at 0 °C (32.0 °F). Continental climates are classified as D and considered to be varieties of temperate climates, having more extreme temperatures, with mean temperatures in

238-583: A region of 180 km by 310 km. Here, for a distance of over 300 km, three of Asia's great rivers run roughly parallel to one another though separated by high mountain ranges with peaks over 6,000 meters. After this area of near confluence , the rivers greatly diverge: the Nujiang River becomes Salween and empties out at Moulmein , Burma , into the Indian Ocean , the Lancang becomes

272-469: A summer accent on rainfall. Regions with humid continental climates include southeastern Canada, the upper portions of the eastern United States , portions of eastern Europe , parts of China , Japan and the Korean Peninsula . These are temperate climates that compared to the subtropics are on the poleward edge of the temperate zone. Therefore, they still have four marked seasons including

306-435: A temperate region is found in southern Africa , where some 24,000 taxa (species and infraspecific taxa) have been described. Farming is a large-scale practice in the temperate regions (except for boreal/subarctic regions) due to the plentiful rainfall and warm summers, because most agricultural activity occurs in the spring and summer, cold winters have a small effect on agricultural production. Extreme winters or summers have

340-646: A warmer one, but are far more influenced by the polar zones than any other but the very polar climates ( tundra and ice cap climate ). Areas with subpolar oceanic climates feature an oceanic climate but are usually located closer to polar regions. As a result of their location, these regions tend to be on the cool end of oceanic climates. Snowfall tends to be more common here than in other oceanic climates. Subpolar oceanic climates are less prone to temperature extremes than subarctic climates or continental climates , featuring milder winters than these climates but still with similar summers. This variant of an oceanic climate

374-626: Is found in parts of coastal Iceland , the Faroe Islands , parts of Scotland , northwestern coastal areas of Norway such as Lofoten and reaching to 70° north on some islands, uplands near the coast of southwestern Norway, the Aleutian Islands of Alaska and northern parts of the Alaskan Panhandle , some parts of Southern Argentina and Chile (though most regions are still classified as continental subantarctic), and

408-451: The Köppen climate classification . In contrast to oceanic climates, they are created by large land masses and seasonal changes in wind direction. This causes humid continental climates to have severe temperatures for the season compared to other temperate climates, meaning a hot summer and cold winter. Precipitation may be evenly distributed throughout the year, while in some locations there is

442-657: The Mekong and south of Ho Chi Minh City , Vietnam , empties out into the South China Sea and the Yangtze flows into the East China Sea at Shanghai . Selected nature reserves and places of scenic beauty in this unique region were collectively awarded World Heritage Site status in 2003 for their very rich biodiversity and outstanding topographical diversity. Running parallel to these three rivers, slightly to

476-514: The Three Parallel Rivers region contains many climate types. Average annual precipitation ranges from 4,600 mm in the Dulongjian area in the west of Gongshan county to 300 mm in the upper valleys of the Yangtze river. The protected areas are home to around 6,000 species of plants, 173 species of mammals, and 417 species of birds. Many of the flora and fauna species are endemic to

510-584: The smooth-coated otter , hoolock gibbon , Asian black bear and red panda . Rare bird species in the areas include chestnut-throated partridge , the Lady Amherst's pheasant , white-eared pheasant , Yunnan nuthatch , and giant nuthatch ; the white-speckled laughingthrush , ferruginous duck , Severtzov's grouse , and brown-winged parrotbill ; the Ward's trogon , black-necked crane and Verreaux's monal-partridge . Temperate In geography ,

544-596: The temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth . These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates , where such variations are often small; they usually differ only in the amount of precipitation . In temperate climates, not only do latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large

578-513: The Cwb classification have significant monsoon influence, usually having dry winters and wet summers. These climates occur in the middle latitudes, between approximately 35° and 66.5° north and south of the equator. There is an equal climatic influence from both the polar and tropical zones in this climate region. Two types of climates are in this zone, a milder oceanic one and more severe seasonal continental one. Most prototypical temperate climates have

612-554: The Ganges-Brahmaputra. They are all among the top 15 rivers in Asia by volume or length. In its description, UNESCO mentions: "(It) may be the most biologically diverse temperate region on earth" and "An exceptional range of topographical features - from gorges to karst to glaciated peaks -- is associated with the site being at a 'collision point' of tectonic plates ". Due to its topography and geographical location,

646-543: The areas includes 173 species of mammals, of which 81 are endemic, and 417 species of birds, of which 22 are endemic. Some of the mammals which inhabit these regions are the endemic black snub-nosed monkey , the Indian leopard , snow leopard , and clouded leopard ; the Gaoligong pika , Gongshan muntjac , Chinese shrew mole , and capped langur ; the stump-tailed macaque , Asiatic wild dog , black musk deer , and takin ;

680-614: The coldest month usually being below −3 °C (26.6 °F). The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic Circle (approximately 66.5° north latitude). The south temperate zone extends from the Tropic of Capricorn (approximately 23.5° south latitude) to the Antarctic Circle (at approximately 66.5° south latitude). In some climate classifications,

714-410: The continental climate. Regions with oceanic climates include northwestern Europe , northwestern North America , southeastern and southwestern South America , southeastern Australia and most of New Zealand . Humid continental climates are considered as a variety of temperate climates due to lying in the temperate zones, although they are classified separately from other temperate climates in

748-476: The humid subtropics. Warm ocean currents are usually found in coastal areas with humid subtropical climates. This type of climate is normally located along leeward lower east coasts of continents such as in southeast and central Argentina , Uruguay and south of Brazil , the southeast portions of East Asia , southern and portions of the northeast and midwestern United States and portions of, South Africa , Ethiopia , and eastern Australia . In some areas with

782-547: The monsoon-influenced subtropical highland climate similar to subpolar oceanic climates occurs in small areas in Yunnan, Sichuan and parts of the Altiplano between Bolivia , Peru and Chile , where summers are sufficiently short to be Cwc with fewer than four months over 10 °C (50 °F) due to the high altitudes at these locations. El Alto, Bolivia , is one of the few confirmed towns that features this variation of

816-517: The opposite rainfall pattern to dry-winter climates, with a dry summer and wet winter. This climate occurs mostly at the western edges and coasts of the continents and are bounded by arid deserts on their equatorward sides that brings dry winds causing the dry season of summer, and oceanic climates to the poleward sides that are influenced by cool ocean currents and air masses that bring the rainfall of winter. The five main Mediterranean regions of

850-650: The opposite rainfall pattern. This climate is rare and is predominantly found in climate fringes and isolated areas of the Cascades and Andes Mountains , as the dry-summer climate extends further poleward in the Americas than elsewhere. The vast majority of the world's human population resides in temperate zones, especially in the Northern Hemisphere , due to its greater mass of land and lack of extreme temperatures. The biggest described number of taxa in

884-803: The region. The Three Parallel Rivers has been acknowledged as a natural World Heritage Site. Demographically, the region contains many of the twenty-five ethnic groups found in Yunnan province (including the Derung , the smallest of all of China's minority groups). Other minorities found in this region include the Tibetan people , the Nu people , the Lisu , the Bai , the Pumi and the Naxi . Many of these minorities still use traditional costumes as their normal daily attire. In

918-642: The same region as the Three Parallel Rivers of Yunnan Protected Areas lies the Old Town of Lijiang , which is also a World Heritage Site in its own right. The Three Parallel Rivers of Yunnan Protected Areas consists of fifteen protected areas, in eight geographic clusters. The areas include: According to UNESCO "The area covered by the World Heritage site is claimed to be the most biodiverse and least disturbed temperate ecosystems in

952-509: The subtropical highland climate. Cold summer mediterranean climates ( Csc ) are present in high-elevation areas around coastal Csb climate areas, where the strong maritime influence prevents the average winter monthly temperature from dropping below 0 °C. Despite the maritime influence, they are classified alongside other mediterranean climates in the Köppen classification rather than oceanic climates like subtropical highland climates due to

986-449: The temperate zone may be divided into several smaller climate zones, based on monthly temperatures, the coldest month, and rainfall. These can include the subtropical zone ( humid subtropical and Mediterranean climate ), and the cool temperate zone ( oceanic and continental climates ). These climates are typically found in the more equatorial regions of the temperate zone, between 23.5° and 35° north or south. They are influenced more by

1020-472: The tropics or subtropics. They have characteristically mild temperatures year-round, featuring the four seasons in the subtropics and no marked seasons in the tropics, the latter usually remaining mild to cool through most of the year. Subtropical highland climates under the Cfb classification usually have rainfall spread relatively evenly in all months of the year similar to most oceanic climates while climates under

1054-458: The tropics than by other temperate climate types, usually experiencing warmer temperatures throughout the year, with longer, hotter summers and shorter, milder winters. Freezing precipitation is uncommon in this part of the temperate zone. Humid subtropical climates generally have long, hot and humid summers with frequent convective showers in summer, and a peak seasonal rainfall in the hottest months. Winters are normally mild and above freezing in
