巴西的地理气候英文介绍

Brazil is the largest country in South America. It is the world's fifth largest country, both by geographical area and by population.It is the only Portuguese-speaking country in the Americas and the largest lusophone country in the world.
Bounded by the Atlantic Ocean on the east, Brazil has a coastline of over 7,491 kilometers (4,655 mi). It is bordered on the north by Venezuela, Guyana, Suriname and the French overseas department of French Guiana; on the northwest by Colombia; on the west by Bolivia and Peru; on the southwest by Argentina and Paraguay and on the south by Uruguay. Numerous archipelagos form part of Brazilian territory, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Paul Rocks, and Trindade and Martim Vaz. It has borders with all other South American countries apart from Ecuador and Chile.
Brazil was a colony of Portugal from the landing of Pedro Álvares Cabral in 1500 until 1815, when it was elevated to United Kingdom with Portugal and Algarves. The colonial bond was in fact broken in 1808, when the capital of the Portuguese Kingdom was transferred from Lisbon to Rio de Janeiro, after Napoleon invaded Portugal. The independence from Portugal was achieved in 1822. Initially independent as the Brazilian Empire, the country has been a republic since 1889, although the bicameral legislature, now called Congress, dates back to 1824, when the first constitution was ratified. Its current Constitution defines Brazil as a Federal Republic.The Federation is formed by the union of the Federal District, the 26 States, and the 5,564 Municipalities.
The climate of Brazil comprises a wide range of weather conditions across a large area and varied topography, but most of the country is tropical. According to the Köppen system, Brazil hosts five major climatic subtypes: equatorial, tropical, semiarid, highland tropical, temperate, and subtropical. The different climatic conditions produce environments ranging from equatorial rainforests in the north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil. Many regions have starkly different microclimates.
An equatorial climate characterizes much of northern Brazil. There is no real dry season, but there are some variations in the period of the year when most rain falls. Temperatures average 25 °C (77 °F), with more significant temperature variation between night and day than between seasons.
Over central Brazil rainfall is more seasonal, characteristic of a savanna climate. This region is as extensive as the Amazon basin but has a very different climate as it lies farther south at a higher altitude. In the interior northeast, seasonal rainfall is even more extreme. The semiarid climatic region generally receives less than 800 millimetres (31.5 in) of rain,most of which generally falls in a period of three to five months of the year and occasionally less than this, creating long periods of drought. Brazil's 1877–78 Grande Seca (Great Drought), the most severe ever recorded in Brazil, caused approximately half a million deaths. The one from 1915 was devastating too.
