Question: Where does the columbia river meet where the warm moist air mass over the andes mountains in the country of Amanda O come from?

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. Thus, much of Argentina north of 40 S is dominated by wind circulation patterns from the South Atlantic High. 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. 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. <SEP> tropical and equatorial air masses are hot as they develop over lower latitudes. those that develop over land (continental) are drier and hotter than those that develop over oceans, and travel poleward on the western periphery of the subtropical ridge. maritime tropical air masses are sometimes referred to as trade air masses. monsoon air masses are moist and unstable. superior air masses are dry, and rarely reach the ground. they normally reside over maritime tropical air masses, forming a warmer and drier layer over the more moderate moist air mass below, forming what is known as a trade wind inversion over the maritime tropical air mass. continental polar air masses (cp) are air masses that are cold and dry due to their continental source region. continental polar air masses that affect north america form over interior canada. continental tropical air masses (ct) are a type of tropical air produced by the subtropical ridge over large areas of land and typically originate from low - latitude deserts such as the sahara desert in northern africa, which is the major source of these air masses. other less important sources producing ct air masses are the arabian peninsula, the central arid / semi-arid part of australia and deserts lying in the southwestern united states. continental tropical air masses are extremely hot and dry. <SEP> there is an average of forty - five inches of rain a year (fifty in the mountains). july storms account for much of this precipitation. as much as 15% of the rainfall during the warm season in the carolinas can be attributed to tropical cyclones. mountains usually see some snow in the fall and winter. 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> Amanda O is a comedy, an Internet television series in Argentina produced by Dori Media Group (Dori Media Contenidos). The show features a cast headed by Natalia Oreiro as Amanda O and Luciano Castro as Dante. The show will be on internet at Novebox.com , with a summary on television issued by América 2. It consists of about 120 very short episodes, each approximately eight minutes long. This telenovela has characteristics of a nightmare, dystopia, and science fiction, being drastically different from standard telenovelas, at least approaching serious drama. <SEP> The bar is about 3 miles (5 km) wide and 6 miles (10 km) long. 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.
