Ryukyu Blue Oceans
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate ( Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the i ...

Okinawan Language
The Okinawan language (, , , ) or Central Okinawan, is a Northern Ryukyuan languages, Ryukyuan language spoken primarily in the southern half of the Okinawa Island, island of Okinawa, as well as in the surrounding islands of Kerama Islands, Kerama, Kumejima, Okinawa, Kumejima, Tonaki, Okinawa, Tonaki, Aguni, Okinawa, Aguni and a number of smaller peripheral islands. Central Okinawan distinguishes itself from the speech of Northern Okinawa, which is classified independently as the Kunigami language. Both languages are listed by UNESCO as Atlas of the World's Languages in Danger, endangered. Though Okinawan encompasses a number of local dialects, the Shuri, Okinawa, Shuri–Naha variant is generally recognized as the ''de facto'' standard, as it had been used as the official language of the Ryukyu Kingdom since the reign of King Shō Shin (1477–1526). Moreover, as the former capital of Shuri was built around the royal palace, the language used by the royal court became the regio ...

Amami Islands
The The name ''Amami-guntō'' was standardized on February 15, 2010. Prior to that, another name, ''Amami shotō'' (奄美諸島), was also used. is an archipelago in the Satsunan Islands, which is part of the Ryukyu Islands, and is southwest of Kyushu. Administratively, the group belongs to Kagoshima Prefecture, Japan. The Geospatial Information Authority of Japan and the Japan Coast Guard agreed on February 15, 2010, to use the name of for the Amami Islands. Prior to that, was also used. The name of Amami is probably cognate with , the goddess of creation in the Ryukyuan creation myth. Geography The Amami Islands are limestone islands of coralline origin and have a total area of approximately , of which constitute the city (''-shi'') of Amami, and constitute the district (''-gun'') of Oshima. The highest elevation is ''Yuwandake'' with a height of on Amami Ōshima. The climate is a humid subtropical climate (Köppen climate classification ''Cfa'') with very warm summer ...

Daitō Islands
The are an archipelago consisting of three isolated coral islands in the Philippine Sea southeast of Okinawa. The islands have a total area of and a population of 2,107. Administratively, the whole group belongs to Shimajiri District of Okinawa Prefecture, and is divided between the villages of Minamidaitō and Kitadaitō, with uninhabited Okidaitōjima island administered as part of Kitadaitō municipality, although physically located closer to Minamidaitōjima. Etymology ''Kita'', ''minami'', and ''oki'' means, respectively, "north", "south", and "offshore" while ''daitō'' means "great east". History These islands have long been known in Okinawa as ''Ufuagari'' (“the Great East”). The islands were first sighted by the Spanish navigator Bernardo de la Torre on 25 September 1543 (Okidaitōjima) and a few days later still in September (Minamidaitōjima and Kitadaitōjima), during his abortive attempt to reach New Spain from the Philippines with the ''San Juan de Letran' ...

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into ...

Tropical Rainforest Climate
A tropical rainforest climate, humid tropical climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, USA, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the Köppen climate classification. A tropical rainforest climate is typically hot, very humid, and wet. Description Tropical rain forests have a type of tropical climate in which there is no dry season—all months have an average precipitation value of at least . There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night ...

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] |
Humid Subtropical Climate
A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification was officially created under the Trewartha climate classification. In this classification, climates are termed humid subtropical when the ...

Coral Island
A coral island is a type of island formed from coral detritus and associated organic material. It occurs in tropical and sub-tropical areas, typically as part of a coral reef which has grown to cover a far larger area under the sea. Ecosystem Coral reefs are some of the oldest ecosystems on the planet, over geological time forming massive reefs of limestone. The reef environment supports more plant and animal species than any other habitat. Coral reefs are vital for life for multiple aspects some of which include structure, ecology, and nutrient cycles which all support biodiversity in the reefs. Coral reefs build massive calcareous skeletons that serve as homes for animals such as fish hiding inside the crooks and crannies of the reef and barnacles attaching themselves directly to the coral’s structure. The structures also help plants that need the sun to photosynthesis, photosynthesize, by lifting the plants to the ocean’s surface where the sunlight can penetrate the wa ...

High Island
Geologically, a high island or volcanic island is an island of volcanic origin. The term can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanos). Definition and origin There are a number of "high islands" that rise no more than above sea level, often classified as "islets or rocks", while some low islands, such as Banaba, Henderson Island, Makatea, Nauru, and Niue, as uplifted coral islands, rise over above sea level. The two types of islands are often found in proximity to each other, especially among the islands of the South Pacific Ocean, where low islands are found on the fringing reefs that surround most high islands. Volcanic islands normally arise above a hotspot. Habitability High islands above a certain size usually have fresh groundwater Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractu ...

Yonaguni
, one of the Yaeyama Islands, is the westernmost inhabited island of Japan, lying from the east coast of Taiwan, between the East China Sea and the Pacific Ocean proper. The island is administered as the Towns of Japan, town of Yonaguni, Okinawa, Yonaguni, Yaeyama, Okinawa, Yaeyama Gun, Okinawa Prefecture, Okinawa, and there are three settlements: Sonai, Kubura, and Higawa. History Early human migration from Taiwan to Yonaguni island has long been the subject of scholarly debate. In 2019, a team of Japanese and Taiwanese researchers succeeded in completing the two-day journey from Cape Wushibi in Taitung County to Yonaguni island along the Kuroshio current in a dugout canoe based on technology and materials from 30,000 years ago. Otherwise, the early history of Yonaguni remains vague. The first written record that ever mentions the island is a 1477 Korean document (''Chosen Hyōryūmin no Yaeyama kenbunroku''), an account of several fishermen from the current Jeju Province who ...

Yaeyama Islands
The Yaeyama Islands (八重山列島 ''Yaeyama-rettō'', also 八重山諸島 ''Yaeyama-shotō'', Yaeyama: ''Yaima'', Yonaguni: ''Daama'', Okinawan: ''Yeema'', Northern Ryukyuan: ''Yapema'') are an archipelago in the southwest of Okinawa Prefecture, Japan, and cover . The islands are located southwest of the Miyako Islands, part of the Ryukyu Islands archipelago. The Yaeyama Islands are the remotest part of Japan from the main islands and contain Japan's most southern (Hateruma) and most western (Yonaguni) inhabited islands. The city of Ishigaki serves as the political, cultural, and economic center of the Yaeyama Islands. Natural history The Yaeyama Islands are home to numerous species of subtropical and tropical plants, and mangrove forests. The islands produce sugarcane and pineapples. Coral reefs around the islands are ideal habitats for dolphins, sea turtles, and larger fish such as manta rays and whale sharks. Before being wiped out by humans, whales and dugongs wer ...
