Carl-Gustaf Rossby

Carl-Gustaf Arvid Rossby (Swedish pronunciation: [kɑːɭˈgʉsˌtav ˈarvɪd ˈrɔsːby] 28 December 1898 – 19 August 1957) was a Swedish born American meteorologist who first explained the large-scale motions of the atmosphere in terms of fluid mechanics. He identified and characterized both the jet stream and the long waves in the westerlies that were later named Rossby waves.

Biography

Carl-Gustaf Rossby was born in Stockholm, Sweden. He was the first of five children born to Arvid and Alma Charlotta (Marelius) Rossby. He attended the Stockholm University where he developed his first interest in mathematical physics. Rossby came into meteorology and oceanography while studying geophysics under Vilhelm Bjerknes at the Geophysical Institute, University of Bergen in Bergen, Norway during 1919, where Bjerknes' group was developing the groundbreaking concepts that became known as the Bergen School of Meteorology, including theory of the polar front.

He also studied at the University of Leipzig and at the Lindenberg Observatory (Meteorologischen Observatorium Lindenberg) in Brandenburg where upper air measurements by kite and balloon were researched. In 1921 he returned to Stockholm to join the Swedish Meteorological and Hydrological Institute (SMHI) where he served as a meteorologist on a variety of oceanographic expeditions. While ashore between expeditions, he studied mathematical physics at the University of Stockholm.

Crater (Aden)

Crater (/ˈkreɪtər/; Arabic: كريتر‎, [ˈkɾeːtəɾ]), also Kraytar, is a district of the Aden Governorate, Yemen. Its official name is Seera (Arabic: صيرة Ṣīrah). It is situated in a crater of an ancient volcano which forms the Shamsan Mountains. In 1991, the population was 70,319. As of 2003, the district had a population of 76,723 people.

In the closing days of British rule in 1967, Crater District became the focus of the Aden Emergency, sometimes called the last imperial war. After a mutiny of hundreds of soldiers in the South Arabian Federation Army on 20 June, all British forces withdrew from the Crater. The Crater was occupied by Arab fighters while British forces blocked off its two main entrances. In July, a British infantry battalion, led by Lt. Col. Colin Mitchell of the Argyll & Sutherland Highlanders, entered the Crater and managed to occupy the entire district overnight with no casualties. Nevertheless, deadly guerrilla attacks soon resumed, with the British leaving Aden by the end of November 1967, earlier than had been planned by British Prime Minister Harold Wilson and without an agreement on the succeeding governance.

Crater (Chinese astronomy)

According to traditional Chinese uranography, the modern constellation Crater is located within the southern quadrant of the sky, which is symbolized as the Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què).

The name of the western constellation in modern Chinese is 巨爵座 (jù jué zuò), meaning "the huge wine holder constellation".
