Volta Do Mar
, , or (the phrase in Portuguese means literally 'turn of the sea' but also 'return from the sea') is a navigational technique perfected by Portuguese navigators during the Age of Discovery in the late fifteenth century, using the dependable phenomenon of the great permanent wind circle, the North Atlantic Gyre. This was a major step in the history of navigation, when an understanding of winds in the age of sail was crucial to success: the European sea empires would not have been established without an understanding of the trade winds. History Portuguese discovery in the Atlantic Ocean The was a sailing technique discovered in successfully returning from the Atlantic islands, where the pilot first had to sail far to the west in order to catch usable following winds, and return to Europe. This was a counter-intuitive sailing direction, as it required the pilot to steer in a direction that was perpendicular to the ports of Portugal. Lack of this information may have d ...

Westerlies
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. The westerlies are strongest in the winter hemisphere and times when the pressure is lower over the poles, while they are weakest in the summer hemisphere and when pressures are higher over the poles. The westerlies are particularly strong, especially in the Southern Hemisphere (called also 'Brave West winds' at striking Chile, Argentina, Tasmania and New Zealand), in areas where land is absent, bec ...

North Pacific Gyre
The North Pacific Gyre (NPG) or North Pacific Subtropical Gyre (NPSG), located in the northern Pacific Ocean, is one of the five major oceanic gyres. This gyre covers most of the northern Pacific Ocean. It is the largest ecosystem on Earth, located between the equator and 50° N latitude, and comprising 20 million square kilometers. The gyre has a clockwise circular pattern and is formed by four prevailing ocean currents: the North Pacific Current to the north, the California Current to the east, the North Equatorial Current to the south, and the Kuroshio Current to the west. It is the site of an unusually intense collection of human-created marine debris, known as the Great Pacific Garbage Patch. The North Pacific Subtropical Gyre and the much smaller North Pacific Subpolar Gyre make up the two major gyre systems in the mid-latitudes of the Northern Pacific Ocean. This two-gyre circulation in the North Pacific is driven by the trade and westerly winds. This is one of the be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Manila Galleon
The Manila galleon (; ) refers to the Spain, Spanish trading Sailing ship, ships that linked the Philippines in the Spanish East Indies to Mexico (New Spain), across the Pacific Ocean. The ships made one or two round-trip voyages per year between the ports of Manila and Acapulco from the late 16th to early 19th century. The term "Manila galleon" can also refer to the trade route itself between Manila and Acapulco that was operational from 1565 to 1815. The Manila galleon trade route was inaugurated in 1565 after the Augustinians, Augustinian friar and navigator Andrés de Urdaneta pioneered the ''tornaviaje'' or return route from the Philippines to Mexico. Urdaneta and Alonso de Arellano made the first successful round trips that year, by taking advantage of the Kuroshio Current. The galleons set sail from Cavite, in Manila Bay, at the end of June or the first week of July, sailing through the northern Pacific and reaching Acapulco in March to April of the next calendar year.

16th Century Portuguese Spanish Trade Routes
16 (sixteen) is the natural number following 15 and preceding 17. It is the fourth power of two. In English speech, the numbers 16 and 60 are sometimes confused, as they sound similar. Mathematics 16 is the ninth composite number, and a square number: 42 = 4 × 4 (the first non-unitary fourth-power prime of the form ''p''4). It is the smallest number with exactly five divisors, its proper divisors being , , and . Sixteen is the only integer that equals ''m''''n'' and ''n''''m'', for some unequal integers ''m'' and ''n'' (m=4, n=2, or vice versa). It has this property because 2^=2\times 2. It is also equal to 32 (see tetration). The aliquot sum of 16 is 15, within an aliquot sequence of four composite members (16, 15, 9, 4, 3, 1, 0) that belong to the prime 3-aliquot tree. *Sixteen is the largest known integer , for which 2^n+1 is prime. *It is the first Erdős–Woods number. *There are 16 partially ordered sets with four unlabeled elements. 16 is the only num ...

Oceanic Gyres
In oceanography, a gyre () is any large system of ocean current, ocean surface currents moving in a circular fashion driven by wind movements. Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the ''wind stress Curl (mathematics), curl'' (torque). ''Gyre'' can refer to any type of vortex in an planetary atmosphere, atmosphere or a Planetary ocean, sea, even one that is human-created, but it is most commonly used in terrestrial oceanography to refer to the major ocean systems. Gyre formation The largest ocean gyres are wind-driven, meaning that their locations and dynamics are controlled by the prevailing Prevailing winds, global wind patterns: Trade winds, easterlies at the tropics and westerlies at the midlatitudes. These wind patterns result in a wind stress curl that drives Ekman transport#Ekman pumping, Ekman pumping in the subtropics (resulting in downwelling) and Ekman transport# ...
