Question: Where does the Columbia River meet the source of the warm moist air mass over the Andes where El Alma de un tango's director is a citizen?

<P0-S0> The film was part of the popular genre of tango films. <P0-S1> The Soul of a Tango (Spanish:El Alma de un tango) is a 1945 Argentine musical film directed and written by Julio Irigoyen and starring Héctor Palacios, Elisa Labardén and Lea Conti. <P0-S2> It premiered on 20 April 1945. <SEP> <P1-S0> Although the centre and the eastern parts of the country are mostly flat, the west is mountainous. <P1-S1> 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. <P1-S2> 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. <P1-S3> Here, the Andes exert an important influence on the climate. <P1-S4> Thus, much of Argentina north of 40 S is dominated by wind circulation patterns from the South Atlantic High. <P1-S5> 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. <P1-S6> However, the north -- south orientation of the Andes creates a barrier for humid air masses originating from the Pacific Ocean. <P1-S7> This is because they force these air masses upwards, cooling adiabactically. <P1-S8> 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. <P1-S9> Thus, an extensive rain -- shadow is present in much of Patagonia, causing it to receive very little precipitation. <P1-S10> The Sierras Pampeanas influences the climate on a much smaller scale than the Andes. <SEP> <P2-S0> alberto sileoni enrolled in the university of buenos aires and earned a degree in history, in 1975. he later taught the discipline at his alma mater, and in 1993, was named director of adult education services for the city of buenos aires. <P2-S1> he was shortly afterwards appointed the city's undersecretary of education, remaining in the post until the election of mayor fernando de la rúa, in 1996. <SEP> <P3-S0> The bar is about 3 miles (5 km) wide and 6 miles (10 km) long. <P3-S1> 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. <SEP> <P4-S0> there is an average of forty - five inches of rain a year (fifty in the mountains). <P4-S1> july storms account for much of this precipitation. <P4-S2> as much as 15% of the rainfall during the warm season in the carolinas can be attributed to tropical cyclones. <P4-S3> mountains usually see some snow in the fall and winter. <P4-S4> moist winds from the southwest drop an average of 80 inches (2,000 mm) of precipitation on the western side of the mountains, while the northeast - facing slopes average less than half that amount. <SEP> <P5-S0> 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".
