42-520: Sikhote-Alin is a temperate zone , though species typical of northern taiga (such as reindeer and the Ussuri brown bear ) coexist with the Amur tiger , Amur leopard , and Asiatic black bear . The region holds very few wolves , due to competition with tigers. The longest-lived tree in the region is a millennium-old Japanese yew . It is the only known habitat of Sikhotealinia , the only living member of

84-519: A millennium . This wobble means that the Tropic of Cancer is currently drifting southward at a rate of almost half an arcsecond (0.468″) of latitude, or 15 m (49 ft), per year. The circle's position was at exactly 23° 27′N in 1917 and will be at 23° 26'N in 2045. The distance between the Antarctic Circle and the Tropic of Cancer is essentially constant as they move in tandem. This

126-428: 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

168-424: 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

210-809: 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

252-421: 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

294-434: 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

336-469: 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

378-435: 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

420-646: 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

462-582: Is based on an assumption of a constant equator, but the precise location of the equator is not truly fixed. See: equator , axial tilt and circles of latitude for additional details. Download coordinates as: North of the tropic are the subtropics and the North Temperate Zone . The equivalent line of latitude south of the Equator is called the Tropic of Capricorn , and the region between

504-626: 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

546-560: Is the burning of fossil fuels from buildings and vehicles. These factors have led to the average climate of cities to be warmer than surrounding areas . Tropic of Cancer 23°26′12.5″N 0°0′0″W  /  23.436806°N -0.00000°E  / 23.436806; -0.00000  ( Prime Meridian ) The Tropic of Cancer , also known as the Northern Tropic , is the Earth 's northernmost circle of latitude where

588-451: 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

630-759: The Sun can be seen directly overhead . This occurs on the June solstice , when the Northern Hemisphere is tilted toward the Sun to its maximum extent. It also reaches 90 degrees below the horizon at solar midnight on the December Solstice . Using a continuously updated formula, the circle is currently 23°26′09.8″ (or 23.43605°) north of the Equator . Its Southern Hemisphere counterpart, marking

672-598: The World Heritage List , citing its importance for "the survival of endangered species such as the scaly-sided (Chinese) merganser , Blakiston's fish-owl and the Amur tiger ". The World Heritage Site had a total area of 16,319 square kilometres (4,033,000 acres), of which the terrestrial core zone of Sikhote-Alin Zapovednik comprised 3,985 square kilometres (985,000 acres). In 2018, the World heritage Site

714-405: The plane of its orbit , and since the tilt changes, the location of these two circles also changes. In geopolitics , it is known for being the southern limitation on the mutual defence obligation of NATO , as member states of NATO are not obligated to come to the defence of territory south of the Tropic of Cancer. When this line of latitude was named in the last centuries BCE , the Sun was in

756-513: 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

798-463: The Tropic of Cancer experience two distinct seasons: an extremely hot summer with temperatures often reaching 45 °C (113 °F) and a warm winter with maxima around 22 °C (72 °F). Much land on or near the Tropic of Cancer is part of the Sahara Desert , while to the east, the climate is torrid monsoonal with a short wet season from June to September, and very little rainfall for

840-529: The beetle family Jurodidae , which have been described as the “most mysterious representatives of beetles” due to their uncertain placement within the group. Many tributaries of the Amur River lie within the range, including the Gur . The core zone can only be explored in a company of rangers. The name is thought to be of Manchu origin ( Manchu : alin "mountain"). In the 1910s and 1920s, Sikhote-Alin

882-496: 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,

924-524: The constellation Cancer ( Latin : Crab ) at the June solstice (90° ecliptic longitude ). Due to the precession of the equinoxes , this is no longer the case; today the Sun is in constellation Taurus at the June solstice. The word "tropic" itself comes from the Greek "trope (τροπή)", meaning turn (change of direction or circumstance), inclination, referring to the fact that the Sun appears to "turn back" at

966-410: 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

1008-483: The following 17 countries (including two disputed territories) and 8 water bodies, starting at the prime meridian and heading eastward: The climate at the Tropic of Cancer is generally hot and dry, except for cooler highland regions in China, marine environments such as Hawaii, and easterly coastal areas, where orographic rainfall can be very heavy, in some places reaching 4 metres (160 in) annually. Most regions on

1050-476: 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

1092-405: The largest meteorite showers in recent history occurred in the mountains range. The Sikhote-Alin meteorite exploded in the atmosphere as it fell, raining many tons of metal on an elliptical region about 1.3 square kilometres (0.50 sq mi) in area. Craters were formed by the meteorites; the largest was 26 metres (85 ft) in diameter. In 2001, UNESCO placed "Central Sikhote-Alin" onto

1134-547: 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

1176-512: The most southerly position at which the Sun can be seen directly overhead, is the Tropic of Capricorn . These tropics are two of the five major circles of latitude that mark maps of Earth, the others being the Arctic and Antarctic circles and the Equator . The positions of these two circles of latitude (relative to the Equator) are dictated by the tilt of Earth's axis of rotation relative to

1218-517: 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

1260-580: 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

1302-705: The rest of the year. The highest mountain on or adjacent to the Tropic of Cancer is Yu Shan in Taiwan . It had glaciers descending as low as 2,800 metres (9,190 ft) during the Last Glacial Maximum . At present glaciers still exist around the Tropic. The nearest currently surviving are the Minyong and Baishui in the Himalayas to the north and on Iztaccíhuatl in Mexico to the south. According to

1344-503: The rules of the Fédération Aéronautique Internationale , for a flight to compete for a round-the-world speed record, it must cover a distance no less than the length of the Tropic of Cancer, cross all meridians , and end on the same airfield where it started. The length of the Tropic of Cancer is 36,788 km (22,859 mi): For an ordinary circumnavigation the rules are somewhat relaxed and

1386-452: The solstices. The Tropic of Cancer's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to the ecliptic , the plane in which the Earth orbits around the Sun. Earth's axial tilt varies over a 41,000-year period from about 22.1 to 24.5 degrees, and as of 2000 is about 23.4 degrees, which will continue to remain valid for about

1428-509: 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

1470-449: 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

1512-472: 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

1554-458: 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

1596-401: The two, centered on the Equator, is the tropics . In the year 2000, more than half of the world's population lived north of the Tropic of Cancer. On the Tropic of Cancer there are approximately 13 hours, 35 minutes of daylight during the summer solstice. During the winter solstice, there are 10 hours, 41 minutes of daylight. Using 23°26'N for the Tropic of Cancer, the tropic passes through

1638-717: The world are the Mediterranean Basin in North Africa , Southern Europe , and West Asia , coastal California in the United States , the South and West states of Australia , the Western Cape of South Africa and the south and southwestern coast of Chile . Subtropical highland climates are climate variants often grouped together with oceanic climates found in some mountainous areas of either

1680-454: 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 a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines

1722-548: Was expanded by 11,605 square kilometres (2,868,000 acres) by including Bikin National Park under the name "Bikin River Valley". Temperate zone In geography , 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
