In order to determine in which climatic zones is the Atlantic Ocean, just look at the map of the world.It stretches from the northern ice islands and ends at the coast of Antarctica, crossing the Equator and all the surrounding natural areas.In each district of the weather conditions over the waters different.Somewhere dominated by the trade winds, somewhere in the monsoon.There are areas of reduced pressure, there is very high.Because we now consider in more detail in which climatic zones is the Atlantic Ocean, as well as highlighting their key features.
data on Atlantic
Its parameters and volume of water masses Atlantic Ocean is the second largest in the world after the Pacific.It is located between the shores of Europe and North America, between Africa and South America.In the North, it originates off the coast of Iceland, and in the south to the glaciers of Antarctica touches.On the territory of this vast water reservoir is not so, and a lot of islands, and this is one of its features.The fact that the relief of the ocean bottom has formed a long time, compared to, for example, the Indian, because the majority of dormant volcanoes here, and tectonic plates are in a state of rest.Nevertheless, all of the islands that were formed here are just volcanic origin, regardless of their settings.So we looked at, where the Atlantic Ocean with respect to the mainland.Now go to its weather conditions.
Brief information about climate
Despite the fact that the Atlantic has a very impressive meridional slowness, air temperature and humidity here as to "align" due to water currents.One of them is the Gulf Stream, which carries warm waters off the coast of Central America to Northern Europe.Due to the fact that along the western coast of Eurasia flow warm water, the climate here is very mild and stable.Gulfstream also provides the northern part of the ocean higher average temperature readings.In the South, where there are greater extremes of temperature throughout the seasons and a sharp change of weather.
Features locations
relative position of the Atlantic continents - the main reason that in the Northern Hemisphere surface water and the air is heated more strongly than in the South.The fact that its width in the upper part of the planet is small compared to the south.Here it is between North America and Europe, which is as a compress.In the South, it expands, as it is located between indented lines in Africa and South America.At the bottom of it fueled by the glaciers of Antarctica, which further cools the southern flow.To say with precision what the average temperature of the Atlantic Ocean can not.There are constant for the Northern Hemisphere - 17 degrees above zero, and for the South - 16.
polar regions
We'll start with, in some climatic zones located at the Atlantic coast of the polar.In the north it reaches the Arctic zone, because all are in the subarctic water.Where seasonal temperature variations occur in the range of 15 degrees.In the summer the thermometer column rises to the level of four in winter drops to 15 or more below zero.The northern shores of the Atlantic - a minimum area of the Azores, and the pressure here is always very low.Average rainfall - 250 mm per year.The weather conditions in the South is much more severe.Seasonal changes in temperature up to 25 degrees.Summer bar thermometer rarely rises above zero and in winter drops to -30 or even lower.There is a zone of the South Atlantic low and rainfall is only 100 mm per year.
temperate latitudes
This climate zone roughly identical in both hemispheres of the planet.It is a place of transition from minimum to maximum dynamic, which is located in the tropics.Here seasonal variations in temperature is about 10 degrees (in the South a little more in the North is less), and at the same time, compared to the polar latitudes, the humidity is much higher - 1500 mm per year.In temperate latitudes in winter the air is cooled to not more than -5 Celsius.The temperature of the surface waters of the Atlantic Ocean is never below zero, so they do not freeze.In the summer in the northern hemisphere is warm and dry - up to 25.In the southern part of the ocean temperature rises to a maximum of 22.
Tropical in the North and the South
studying in which climatic zones is the Atlantic Ocean, you can not miss the tropical zone, one of the most extensive in its territory.At the same time the North tropics hotter and drier than in the South.This is caused by the weather here monsoons that blow from Africa, they often become a cause of storms and tornadoes in the ocean in winter.In the summer here the wind force is reduced, clouds collapsing.South tropical trade winds are light, which may contribute to the shape of continents, or above the water surface.The difference between winter and summer is not as significant as in the North.In tropical latitudes of the Atlantic annual temperature fluctuations are no more than 2 degrees.On average, the thermometer shows 25.Also note that this zone is considered to be a dynamic maximum.There is very little rain falls, not more than 200 mm per year, and in some areas - only 50 mm.
Equatorial Zone
between the Tropic Zone is a dynamic minimum.There is always the highest temperature readings, and thus very high humidity.It is caused by cyclones that form over the waters of a great veil of clouds and fog throughout the year.The average temperature of the Atlantic Ocean near the equator - is 28 degrees.Rainfall here sometimes falls about 3000 mm per year.It is near the equator, between his band and the tropics, there are two archipelagos which are considered the best place for a beach holiday.This is the Canary Islands, with a developed infrastructure, as well as the Cape Verde Islands (Cape Verde) - a place for fans of extreme tourism, unusual scenery and unique equatorial nature.
