Typhoon Songda (2004)
Typhoon Songda, known in the Philippines as Typhoon Nina, was the sixth-costliest typhoon on record. The 18th named storm of the 2004 Pacific typhoon season, Songda developed on August 26 near the Marshall Islands. Following a path that Typhoon Chaba took nine days prior, Songda moved west-northwestward and strengthened quickly amid favorable conditions. Meteorological history Forming in a similar region as Typhoon Chaba did nine days earlier, Typhoon Songda originated on August 26 from an area of convection, or thunderstorms, east-northeast of Kwajalein in the Marshall Islands. At 06:00 UTC that day, the Japan Meteorological Agency (JMA) assessed that a tropical depression developed. The convection steadily organized and consolidated into rainbands around a well-developed circulation, aided by low wind shear. At 11:30 UTC on August 28, the Joint Typhoon Warning Center issued a tropical cyclone formation alert, and just 30 minutes later upgraded th ...

Real And Nominal Value
In economics, nominal value refers to value measured in terms of absolute money amounts, whereas real value is considered and measured against the actual goods or services for which it can be exchanged at a given time. Real value takes into account inflation and the value of an asset in relation to its purchasing power. In macroeconomics, the real gross domestic product compensates for inflation so economists can exclude inflation from growth figures, and see how much an economy actually grows. Nominal GDP would include inflation, and thus be higher. Commodity bundles, price indices and inflation A commodity bundle is a sample of goods, which is used to represent the sum total of goods across the economy to which the goods belong, for the purpose of comparison across different times (or locations). At a single point of time, a commodity bundle consists of a list of goods, and each good in the list has a market price and a quantity. The market value of the good is the market p ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of Oxygen saturation, dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to politi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed Isobar (meteorology), isobaric contour that would define it as a Low-pressure area, low pressure area. Since low pressure implies a low Geopotential height, height on a pressure surface, Valley, troughs and Ridge (meteorology), ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at altitude. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect Cyclonic rotation, cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions ...

Kyushu
is the third-largest island of Japan's Japanese archipelago, four main islands and the most southerly of the four largest islands (i.e. excluding Okinawa Island, Okinawa and the other Ryukyu Islands, Ryukyu (''Nansei'') Ryukyu Islands, Islands). In the past, it has been known as , and . The historical regional name referred to Kyushu and its surrounding islands. Kyushu has a land area of and a population of 14,311,224 in 2018. In ancient times, there is a theory that Kyushu was home to its own independent dynasty, where a unique, southern-influenced culture and tradition distinct from that of Honshu flourished. In the 8th-century Taihō Code reforms, Dazaifu (government), Dazaifu was established as a special administrative term for the region. Geography The island is mountainous, and Japan's most active volcano, Mount Aso at , is on Kyūshū. There are many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nagasaki
, officially , is the capital and the largest Cities of Japan, city of Nagasaki Prefecture on the island of Kyushu in Japan. Founded by the Portuguese, the port of Portuguese_Nagasaki, Nagasaki became the sole Nanban trade, port used for trade with the Portuguese and Dutch during the 16th through 19th centuries. The Hidden Christian Sites in the Nagasaki Region have been recognized and included in the World Heritage Sites in Japan, UNESCO World Heritage Sites list. Part of Nagasaki was home to a major Imperial Japanese Navy base during the First Sino-Japanese War and Russo-Japanese War. Near the end of World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second city in the world to experience a nuclear attack. The city was rebuilt. , Nagasaki has an estimated population of 392,281, and a population density of 966 people per km2. The total area is .

Okinawa, Okinawa
is the second-largest city in Okinawa Prefecture, Japan, following Naha, the capital city. It is located in the central part of the island of Okinawa, about north of Naha. As of 1 October 2020, the city has an estimated population of 142,752 and a population density of 2,913.31 people per km2. The total area is 49.00 km2. History Under the Ryukyu Kingdom the present-day area of Okinawa City was occupied by two magiri, a type of administrative district. The Goeku magiri occupied the south of the city, and the north of the city was part of the Misato magiri. In 1908, Okinawa Prefecture ended the magiri system and established the villages of Goeku and Misato. Both villages were agricultural and lacked urbanized areas prior to World War II. After the Battle of Okinawa the United States established the first refugee camp in Okinawa in the area south of present-day Kadena Air Base. The population of the former villages swelled rapidly. An area of Goeku, called ''Goya'' (ごや ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfall (meteorology)
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there.' Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the center of its eye (cyclone), eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding Rain, rains. These coupled with high surf can cause major coastal erosion, beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environ ...

Outflow (meteorology)
Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclone, anticyclonic flow. In the low levels of the troposphere, outflow radiates from thunderstorms in the form of a wedge of rain-cooled air, which is visible as a thin rope-like cloud on weather satellite imagery or a fine line on weather radar imagery. For observers on the ground, a thunderstorm outflow boundary often approaches in otherwise clear skies as a low, thick cloud that brings with it a gust front. Low-level outflow boundaries can disrupt the center of small tropical cyclones. However, outflow aloft is essential for the strengthening of a tropical cyclone. If this outflow is restricted or undercut, the tropical cyclone weakens. If two tropical cyclones are close, the upper-level outflow from the upwind system can limit the development of the other system. Thunderstorms For thunderstorms, outflow tends to indicate the development of a system. Large quan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agrihan
Agrihan (also spelled Agrigan) is an island in the Northern Mariana Islands in the Pacific Ocean. The island has mostly been uninhabited, but had 4 permanent residents in the 2020 U.S. census. Agrihan is located to the north of Pagan. History The first European to discover the island was on June 11, 1522. He named it "Cyco" or "La Griega" (''The Greek'' in Spanish). Espinosa was on the ''Trinidad'' as part of Ferdinand Magellan's expedition, and called on the island while attempting to cross the Pacific Ocean to Mexico. The resident Chamorros were hostile and he could not anchor, but kidnapped an islander for information. The Spanish missionary Diego Luis de San Vitores visited Agrihan in 1669 calling it "San Francisco Javier". In 1695, the natives were forcibly removed to Saipan, and three years later to Guam. In 1810, settlers from the Kingdom of Hawaii attempted to establish a settlement on Agrihan. In the 1870s, the first coconut plantations were established. Adolph Ca ...

Tinian
Tinian () is one of the three principal islands of the Commonwealth of the Northern Mariana Islands (CNMI). Together with uninhabited neighboring Aguiguan, it forms Tinian Municipality, one of the four constituent municipalities of the Northern Marianas. Tinian's largest village is San Jose. Tinian is just south of the Northern Marianas' most inhabited island, Saipan, but north of the populated Rota to the south. The island has many World War II historical sites, cattle ranches, and beaches. There was a 5-star casino that operated from 1998 to 2015; the remaining are other hotels/resorts and a golf course. The main Saipan access is a short airplane ride from the international airport or a charter boat. Tinian is part of the United States and the CNMI. Along with Guam, it is the westernmost U.S. island in the Pacific. History First settlers The Mariana Islands, of which Tinian is one, were the first islands settled by humans in Remote Oceania. It was also the first and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
