Question: Who fathered the leader of the first expedition to reach Hanoi's continent by sailing west across the source of the warm moist air mass over the Andes?

the havre mountains () are a large group of mountains forming the northwestern extremity of alexander island, antarctica, extending in an east–west direction between cape vostok and the russian gap. they were first seen in 1821 by a russian expedition under fabian gottlieb von bellingshausen and re-sighted by the belgian antarctic expedition, 1897–99. they were roughly charted by the french antarctic expedition, 1908–10, under jean-baptiste charcot, who named them for le havre, the french port from which the "pourquol pas?" sailed in 1908. the mountains were mapped in detail from air photos taken by the ronne antarctic research expedition, 1947–48, by d. searle of the falkland islands dependencies survey in 1960. <SEP> Prior to that, Sullivan spent 6 years as the network's South Asia correspondent. Sullivan has received awards from the Overseas Press Club, South Asia Journalists Association, and, with Jennifer Ludden, Loren Jenkins, and Paul Glickman, won the 1998 Robert F. Kennedy Journalism Award for international radio. Sullivan has been at NPR since 1985. Michael D. Sullivan is the Senior Asia Correspondent for National Public Radio (NPR) based in Hanoi since 2003. <SEP> Vasco da Gama's father was Estêvão da Gama, who had served in the 1460s as a knight of the household of Infante Ferdinand, Duke of Viseu. He rose in the ranks of the military Order of Santiago. Estêvão da Gama was appointed "alcaide-mór" (civil governor) of Sines in the 1460s, a post he held until 1478; after that he continued as a receiver of taxes and holder of the Order's commendas in the region. <SEP> 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. <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> The Portuguese Vasco da Gama, accompanied by Nicolau Coelho and Bartolomeu Dias, is the first European to reach India by an all - sea route from Europe.
