Cyclone

In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. According to the National Hurricane Center glossary, warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale.Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune.Cyclogenesis describes the process of cyclone formation and intensification.Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.

  • Yali people

    Yali are major tribal group in Papua, Indonesia, and live to the east of the Baliem Valley in the Papuan highlands. Their major towns are Angguruk and Kosarek, and which are isolated by challenging geography. The major access to their territory is by air. Their territory is known collectively as Yalimo.

    The Yali speak a language that is similar to that of the Dani, although it has distinct differences. The language is in the Ngalik-Nduga subfamily.

    A yalı (Turkish: yalı, from Greek yiáli γιαλή (mod. γιαλός), literally "seashore, beach") is a house or mansion constructed at immediate waterside (almost exclusively seaside, particularly on the Bosphorus strait in Istanbul) and usually built with an architectural concept that takes into account the characteristics of the coastal location. A family who owned a waterside residence would spend some time in this usually secondary residence located at the sea shore, as opposed to the "konak" (mansion, aside from the term's use to refer to buildings with administrative functions) or the "köşk" (pavilion, often serving a determined practical purpose, such as hunting, or implying a temporary nature). Thus, going to the "yalı" acquired the sense of both going to the seaside and to the house situated there. In its contemporary sense, the term "yalı" is used primarily to denote the total amount of 620 waterside residences, mostly dating from the 19th century (some of them date from the 18th century, and some from the early 20th century), sprinkled along the Bosphorus in Istanbul. As such, they constitute one of the city's landmarks.

    Yali School

    Yali High School (simplified Chinese: 雅礼中学; traditional Chinese: 雅禮中學, literally Yali High School), also known as Yali (雅礼) is a senior high school located in Changsha, Hunan Province in the People's Republic of China, or a group of secondary schools containing Yali School itself and several branches. It is a first-tier key school in Hunan's public school system and is one of the most selective schools in the nation. Admission is competitive, based mainly on the score in city-wide or province-wide examinations as well as talent in science, music, sports, and the arts. The school and other three prestigious high schools in Changsha (including First High School of Changsha, Changjun High School and High School Attached to Hunan Normal University), are recognized "the Famous Four".

    In 2007, Yali was included in the "Top 100 Schools" list published by the Top One-Hundred Schools website in China. It topped the list of the five schools that made to the top 100 from Hunan Province (This list published the schools by province and does not rank them nationally.)
