full_context: Document 1: Ulyanovsk Oblast: Ulyanovsk Oblast (Russian: Улья́новская о́бласть, Ulyanovskaya oblast) is a federal subject of Russia (an oblast). It is located in the Volga Federal District. Its administrative center is the city of Ulyanovsk. Population: 1,292,799 (2010 Census).
Document 2: Climate of India: India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate and alpine in the Himalayan north, where elevated regions receive sustained winter snowfall. The nation's climate is strongly influenced by the Himalayas and the Thar Desert. The Himalayas, along with the Hindu Kush mountains in Pakistan, prevent cold Central Asian katabatic winds from blowing in, keeping the bulk of the Indian subcontinent warmer than most locations at the similar latitudes. Simultaneously, the Thar Desert plays a role in attracting moisture - laden southwest summer monsoon winds that, between June and October, provide the majority of India's rainfall. Four major climatic groupings predominate, into which fall seven climatic zones that, as designated by experts, are defined on the basis of such traits as temperature and precipitation. Groupings are assigned codes (see chart) according to the Köppen climate classification system.
Document 3: Vasco da Gama: 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.
Document 4: Chronology of European exploration of Asia: 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.
Document 5: Russia: Russia (/ ˈrʌʃə / (listen); Russian: Росси́я, tr. Rossiya; IPA: (rɐˈsjijə)), also officially known as the Russian Federation (Russian: Российская Федерация, tr. Rossiyskaya Federatsiya; IPA: (rɐˈsijskəjə fjɪdjɪˈratsɨjə)), is a country in Eurasia. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is the largest country in the world by surface area, covering more than one - eighth of the Earth's inhabited land area, and the ninth most populous, with over 144 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern; about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world; other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Chelyabinsk, Nizhny Novgorod, Ufa, and Kazan.
Document 6: Portuguese discovery of the sea route to India: The discovery of the sea route to India is the description sometimes used in Europe and among the Portuguese for the first recorded trip made directly from Europe to India via the Atlantic Ocean. It was undertaken under the command of Portuguese explorer Vasco da Gama during the reign of King Manuel I in 1497 - 1499. Considered by Europe to be one of the most remarkable voyages of the Age of Discovery, it consolidated the Portuguese maritime presence in Pacific Ocean and that country's dominance of global trade routes.
Document 7: Vasco da Gama: Vasco da Gama, 1st Count of Vidigueira (Portuguese pronunciation: (ˈvaʃku ðɐ ˈɣɐmɐ); c. 1460s -- 24 December 1524), was a Portuguese explorer and the first European to reach India by sea. His initial voyage to India (1497 -- 1499) was the first to link Europe and Asia by an ocean route, connecting the Atlantic and the Indian oceans and therefore, the West and the Orient.
Document 8: Chelyabinsk: Chelyabinsk () is a city and the administrative center of Chelyabinsk Oblast, Russia, located in the northeast of the oblast, south of Yekaterinburg, just to the east of the Ural Mountains, on the Miass River, on the border of Europe and Asia. Population:
Document 9: Portuguese India: The first viceroy, Francisco de Almeida, established his headquarters in Cochin (Cochim, Kochi). Subsequent Portuguese governors were not always of viceroy rank. After 1510, the capital of the Portuguese viceroyalty was transferred to Goa. Until the 18th century, the Portuguese governor in Goa had authority over all Portuguese possessions in the Indian Ocean, from southern Africa to southeast Asia. In 1752 Mozambique got its own separate government and in 1844 the Portuguese Government of India stopped administering the territory of Macau, Solor and Timor, and its authority was confined to the colonial holdings on the Malabar coast of present - day India.
Document 10: 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 11: 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 12: Antonio Possevino: Recent scholarship has identified Antonio Possevino's family as New Christians admitted to the learned circles of the court of Renaissance Mantua and its Gonzaga dukes. His father was Piedmontese from Asti and moved to Mantua where he joined the guild of goldsmiths. The family name was changed from Cagliano (Caliano) and had three sons, Giovanni Battista, Antonio and Giorgio. His mother nursed her son Antonio in 1533 together with Francesco III Gonzaga, Duke of Mantua.
Document 13: 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.
