paragraph_text: The United States has the most tornadoes of any country. Many of these form in an area of the central (with some definitions including Southern) United States known as Tornado Alley. This area extends into Canada, particularly the Prairie Provinces and Ontario; however, activity in Canada is less frequent and intense than that of the US. The high frequency of tornadoes in North America is largely due to geography, as moisture from the Gulf of Mexico is easily advected into the midcontinent with few topographic barriers in the way. The Rocky Mountains block Pacific - sourced moisture and buckle the atmospheric flow, forcing drier air at mid-levels of the troposphere due to downsloping winds and causing cyclogenesis downstream to the east of the mountains. Downsloping winds off the Rockies force the formation of a dry line when the flow aloft is strong, while the Gulf of Mexico fuels abundant low - level moisture. This unique topography allows for frequent collisions of warm and cold air, the conditions that breed strong, long - lived storms throughout the year. This area extends into Canada, particularly Ontario and the Prairie Provinces, and strong tornadoes can also occur in northern Mexico.

paragraph_text: 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.

paragraph_text: Spring comes with a gradual warm up from winter, lasting from March 20 through May. Temperatures are generally not hot yet, averaging from 75 -- 82 ° F (23.9 -- 27.8 ° C) in the day and 56 -- 64 ° F (13.3 -- 17.8 ° C) at night. Spring thunderstorms are common, often with spectacular lightning shows. This rainfall prompts Houston's 10 - month - long ``growing season ''to begin. April sees the return of many types of insects, including butterflies and mosquitoes, to Houston's warm climate.

paragraph_text: Patito Feo (in English, Ugly Duckling) is a comedy TV series for kids and teens from Argentina, starring Laura Natalia Esquivel, Brenda Asnicar, Juan Darthes, Griselda Siciliani, Gloria Carrá and Gastón Soffritti produced by Ideas del Sur for Canal 13. The show is distributed worldwide by Televisa. The opening theme, "Un Rincón del Corazón" ("A Corner of the Heart"), is sung by Patito played by Laura Natalia Esquivel.

paragraph_text: 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.

paragraph_text: Kunturillu (Quechua for "black and white", Hispanicized spelling "Condorillo") is a mountain in the Andes of Peru, about high. It is situated in the Ayacucho Region, Huanca Sancos Province, Sancos District.

paragraph_text: The world's longest above - water mountain range is the Andes, about 7,000 km (4,300 mi) long. The range stretches from north to south through seven countries in South America, along the west coast of the continent: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Aconcagua is the highest peak, at about 6,962 m (22,841 ft).

paragraph_text: The Balkan mountains run laterally through the middle of the country. The mountainous southwest has two distinct alpine ranges—Rila and Pirin, which border the lower but more extensive Rhodope Mountains to the east. Musala, at 2,925 metres (9,596 ft), is the highest point in both Bulgaria and the Balkan peninsula, and the Black Sea coast is the country's lowest point. Plains occupy about one third of the territory, while plateaux and hills occupy 41%. Most rivers are short and with low water levels. The longest river located solely in Bulgarian territory, the Iskar, has a length of 368 kilometres (229 mi). Other major rivers include the Struma and the Maritsa in the south.Bulgaria has a changeable climate, which results from being positioned at the meeting point of the Mediterranean and continental air masses combined with the barrier effect of its mountains. Northern Bulgaria averages 1 °C (1.8 °F) cooler, and registers 200 millimetres (7.9 in) more precipitation, than the regions south of the Balkan mountains. Temperature amplitudes vary significantly in different areas. The lowest recorded temperature is −38.3 °C (−36.9 °F), while the highest is 45.2 °C (113.4 °F). Precipitation averages about 630 millimetres (24.8 in) per year, and varies from 500 millimetres (19.7 in) in Dobrudja to more than 2,500 millimetres (98.4 in) in the mountains. Continental air masses bring significant amounts of snowfall during winter.

paragraph_text: Most of Germany has a temperate seasonal climate dominated by humid westerly winds. The country is situated in between the oceanic Western European and the continental Eastern European climate. The climate is moderated by the North Atlantic Drift, the northern extension of the Gulf Stream. This warmer water affects the areas bordering the North Sea; consequently in the northwest and the north the climate is oceanic. Germany gets an average of 789 mm (31 in) of precipitation per year; there is no consistent dry season. Winters are cool and summers tend to be warm: temperatures can exceed 30 °C (86 °F).The east has a more continental climate: winters can be very cold and summers very warm, and longer dry periods can occur. Central and southern Germany are transition regions which vary from moderately oceanic to continental. In addition to the maritime and continental climates that predominate over most of the country, the Alpine regions in the extreme south and, to a lesser degree, some areas of the Central German Uplands have a mountain climate, with lower temperatures and more precipitation.Though the German climate is rarely extreme, there are occasional spikes of cold or heat. Winter temperatures can sometimes drop to two-digit negative temperatures for a few days in a row. Conversely, summer can see periods of very high temperatures for a week or two. The recorded extremes are a maximum of 40.3 °C (104.5 °F) (July 2015, in Kitzingen), and a minimum of −37.8 °C (−36.0 °F) (February 1929, in Pfaffenhofen an der Ilm).

paragraph_text: Pico Polaco is a mountain in the Cordillera de la Ramada range of the Andes Mountains of Argentina. It has a height of although some sources give

paragraph_text: 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.

paragraph_text: The Nissan Leaf, introduced in Japan and the United States in December 2010, became the first modern all - electric, zero tailpipe emission five door family hatchback to be produced for the mass market from a major manufacturer. As of January 2013, the Leaf is also available in Australia, Canada and 17 European countries.

paragraph_text: The 2014 European Cross Country Championships was the 21st edition of the cross country running competition for European athletes which was held in Samokov, Bulgaria, on 14 December 2014. The events were hosted at Borovets – a winter sports and ski resort in the Rila mountains.

paragraph_text: The first inhabitants of North America arrived in Canada at least 15,000 years ago, though increasing evidence suggests an even earlier arrival. It is believed the inhabitants entered the Americas pursuing Pleistocene mammals such as the giant beaver, steppe wisent, musk ox, mastodons, woolly mammoths and ancient reindeer (early caribou). One route hypothesized is that people walked south by way of an ice - free corridor on the east side of the Rocky Mountains, and then fanned out across North America before continuing on to South America. The other conjectured route is that they migrated, either on foot or using primitive boats, down the Pacific Coast to the tip of South America, and then crossed the Rockies and Andes. Evidence of the latter has been covered by a sea level rise of hundreds of metres following the last ice age.

paragraph_text: The area receives about 820 millimetres (32.3 in) of annual rainfall, which is concentrated from June through September/October with little or no precipitation the remainder of the year. The area has two main seasons. The rainy season runs from June to October when winds bring in tropical moisture from the sea. The dry season runs from November to May, when the air is relatively drier. This dry season subdivides into a cold period and a warm period. The cold period spans from November to February when polar air masses push down from the north and keep the air fairly dry. The warm period extends from March to May when tropical winds again dominate but do not yet carry enough moisture for rain.

paragraph_text: The subsequent Great Peace of Montreal was signed in 1701 in Montreal by 39 Indian chiefs and the French. In the treaty, the Iroquois agreed to stop marauding and to allow refugees from the Great Lakes to return east. The Shawnee eventually regained control of the Ohio Country and the lower Allegheny River. The Miami tribe returned to take control of modern Indiana and north - west Ohio. The Pottawatomie went to Michigan, and the Illinois tribe to Illinois. With the Dutch long removed from North America, the English had become just as powerful as the French. The Iroquois came to see that they held the balance of power between the two European powers and they used that position to their benefit for the decades to come. Their society began to quickly change as the tribes began to focus on building up a strong nation, improving their farming technology, and educating their population. The peace was lasting and it would not be until the 1720s that their territory would again be threatened by the Europeans.

paragraph_text: Explorers flying the flag of Spain reached the New World beginning in 1492 with the discovery of America by Christopher Columbus. Spanish expeditions colonized and explored vast areas in North and South America following the grants of the Pope (contained in the 1493 papal bull Inter caetera) and rights contained in the 1494 Treaty of Tordesillas and 1529 Treaty of Zaragoza. These formal acts gave Spain the exclusive rights to colonize the entire Western Hemisphere (excluding eastern Brazil), including all of the west coast of North America. The first European expedition to actually reach the west coast was led by the Spaniard Vasco Núñez de Balboa, who reached the Pacific coast of Panama in 1513. In an act of enduring historical importance, Balboa claimed the Pacific Ocean for the Spanish Crown, as well as all adjoining land and islands. This act gave Spain exclusive sovereignty and navigation rights over the entire west coast of North America.

paragraph_text: The innovation was adopted quickly and new features to air conditioning like the Cadillac Comfort Control which was a completely automatic heating and cooling system set by dial thermostat was introduced as an industry first in the 1964 model year. By 1960 about 20% of all cars in the U.S. had air - conditioning, with the percentage increasing to 80% in the warm areas of the Southwest. American Motors made air conditioning standard equipment on all AMC Ambassadors starting with the 1968 model year, a first in the mass market, with a base price starting at $2,671. By 1969, 54% of domestic automobiles were equipped with air conditioning, with the feature needed not only for passenger comfort, but also to increase the car's resale value.

paragraph_text: Frank Bursley Taylor (1860 – 1938) was an American geologist, the son of a lawyer in Fort Wayne, Indiana. He was a Harvard dropout who studied privately financed in large part by his wealthy father. He became a specialist in the glacial geology of the Great Lakes, and proposed to the Geological Society of America on December 29, 1908 that the continents moved on the Earth's surface, that a shallow region in the Atlantic marks where Africa and South America were once joined, and that the collisions of continents could uplift mountains. His ideas were based on his studies on mountain ranges as the Andes, Rockies, Alps and Himalayas, concluding that these mountains could have been formed only as a result of titanic lateral pressures that thrust the earth's surface upward.
