full_context: Document 1: Oregon: Oregon (/ ˈɔːrɪɡən / (listen)) is a state in the Pacific Northwest region on the West coast of the United States. The Columbia River delineates much of Oregon's northern boundary along Washington state, while the Snake River delineates much of its eastern boundary along Idaho. The parallel 42 ° north delineates the southern boundary with California and Nevada. Oregon is one of only three states of the contiguous United States to have a coastline on the Pacific Ocean.
Document 2: Aroldo Tieri: Born in Corigliano Calabro, son of the journalist and playwright Vincenzo Tieri, Aroldo Tieri moved in Rome at 18 to study law at university, and in the meanwhile approached acting and enrolled the Accademia Nazionale di Arte Drammatica Silvio D'Amico. Graduated in 1938, he almost immediately made his debut in theater and in film. Soon Tieri became one of the most popular and appreciated young actors, with a predisposition to the comic genre. In cinema Tieri specialized in roles on jealous, irascible, nervous boyfriends, and this characterization limited his career and caused his retirement from films in the late 1960s. His versatility was revealed especially on stage and on television, that at the end of the 1950s gave him notoriety with a successful adaptation of the Dickens' novel "Nicholas Nickleby" and then as host of "Canzonissima" in 1960. Companion for many years on the scene of the actress Giuliana Lojodice, later his wife, Tieri formed a stage company with her in 1965 and the couple was very active in multiple projects at theater, radio and TV.

She continued to perform in theater productions well after she left her film career. She was residing in Milan at the time of her death on 15 April 1969.
Document 4: Climate of Argentina: Although the centre and the eastern parts of the country are mostly flat, the west is mountainous. Both the Andes and Sierras Pampeanas affect the climate of Argentina, leading to differences in temperature, pressure, and spatial distribution of precipitation depending on the topography and altitude. Here, the Andes exert an important influence on the climate. Owing to the higher altitudes of the Andes north of 40 S, they completely block the normal westerly flow, preventing low pressure systems containing moisture from the Pacific Ocean from coming in. Thus, much of Argentina north of 40 S is dominated by wind circulation patterns from the South Atlantic High. South of 40 S, the Andes are lower in altitude, allowing much of Patagonia to be dominated by westerly winds and air masses from the Pacific Ocean. However, the north -- south orientation of the Andes creates a barrier for humid air masses originating from the Pacific Ocean. This is because they force these air masses upwards, cooling adiabactically. Most of the moisture is dropped on the Chilean side, causing abundant precipitation and cloudiness while on the Argentine side, the air warms adiabatically, causing it to become drier as it descends. Thus, an extensive rain -- shadow is present in much of Patagonia, causing it to receive very little precipitation. The Sierras Pampeanas influences the climate on a much smaller scale than the Andes.
Document 5: Columbia Bar: The Columbia Bar, also frequently called the Columbia River Bar, is a system of bars and shoals at the mouth of the Columbia River spanning the U.S. states of Oregon and Washington. The bar is about 3 miles (5 km) wide and 6 miles (10 km) long.
Document 6: Warly Ceriani: Ceriani made almost 50 film appearances in Argentina between 1938 and 1959 appearing in films such as the 1942 Julio Irigoyen film "Academia El Tango Argentino".
Document 7: Buenas noches, Buenos Aires: Buenas noches, Buenos Aires is a Argentine musical film comedy directed by and starring Hugo del Carril. The film was premièred in Buenos Aires on October 10, 1964.
Document 8: Canto de amor: Canto de amor is a 1940 Argentine romantic musical drama film, directed and written by Julio Irigoyen. It is based on a tango with music by Osvaldo Fresedo.
Document 9: The Life of Carlos Gardel: The Life of Carlos Gardel (Spanish: La Vida de Carlos Gardel) is a 1939 Argentine musical film directed by Alberto De Zavalia and starring Hugo del Carril, Delia Garces and Elsa O'Connor. The premiered in Buenos Aires on May 24, 1939. The film is a biopic, portraying the life of the French-born tango singer Carlos Gardel (1890-1935) who became a popular film star in Argentina and the United States. The film was a major success, due largely to the lasting popularity of Gardel following his sudden death in an airplane crash four years before. The film boosted the careers of its stars, and was part of what became known as the Golden Age of Argentine Cinema.
Document 10: Mi Buenos Aires querido (1936 film): Mi Buenos Aires querido is a 1936 Argentine musical film directed and written by Julio Irigoyen. It is a tango film.
Document 11: Alps: The Alps are a classic example of what happens when a temperate area at lower altitude gives way to higher-elevation terrain. Elevations around the world that have cold climates similar to those of the polar regions have been called Alpine. A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease (see adiabatic lapse rate). The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of temperature, often accompanied by precipitation in the form of snow or rain. The height of the Alps is sufficient to divide the weather patterns in Europe into a wet north and a dry south because moisture is sucked from the air as it flows over the high peaks.
Document 12: Bridge of the Gods (land bridge): The Bridge of the Gods was a natural dam created by the Bonneville Slide, a major landslide that dammed the Columbia River near present-day Cascade Locks, Oregon in the Pacific Northwest of the United States. The river eventually breached the bridge and washed much of it away, but the event is remembered in local legends of the Native Americans as the "Bridge of the Gods".

The film was part of the popular genre of tango films. It premiered on 20 April 1945.
Document 14: Sahara: The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.
Document 15: Columbia Gorge AVA: The Columbia Gorge AVA is an American Viticultural Area which includes land surrounding the Columbia River Gorge, straddling the border between Oregon and Washington. Due to the significant gradations of climate and geography found in the gorge, this AVA exhibits a wide range of terroir in a relatively small region; it is marketed as a "world of wine in 40 miles".
