Atlantic waters extend from the northernmost latitudes, pass through the equator and reach the coast of Antarctica.In each of these zones forms the flow which greatly affects the weather and water temperature.Climatic zones of the Atlantic Ocean - this arctic and equatorial tropics ... and, of course, to compare them with terrestrial species of the same name can not be climate - the difference is too great.Because in order to identify them correctly, we need a brief description of the Atlantic Ocean, its location and features.
Short description
So the Atlantic Ocean is the second largest water reservoir in the world.Its area is over 91 million square kilometers, and the volume - 330 million cubic kilometers.The greatest ocean depth - 8742 meters, it is located near the Puerto Rico trench.The salinity of the water is 36 per cent, making it the most saline body of water in the world.Another characteristic of the Atlantic Ocean - is its indented coastline.Along the shores of all continents, which are washed by the waters of the Atlantic, there are the sea, bays and straits, which are included in its composition.Overall, they account for approximately 16% of total water.
Geographical location
Climatic zones of the Atlantic Ocean are due to its geographical position.Pond stretches from the north of the planet, that is, from Greenland and Iceland, to the south - to Antarctica.In the west it is bordered by the shores of North and South America, and in the east - with Europe and Africa.In the waters of the Atlantic there is a set of islands of volcanic origin, mostly.Many of them are part of the Sea, which belong to the ocean.Among these can be called the Balearic, Malta (Mediterranean), Greater and Lesser Antilles (Caribbean).In the vastness of the ocean are the Canary Islands, Cape Verde (Cape Verde), Sandwich, Faroe and many others.All of them are of volcanic origin, and the temperature in coastal waters depends on what kind of climatic zones of the Atlantic Ocean surround them.
Northern Hemisphere
main features of the Atlantic lies in the fact that the climate zones, which are located in its waters are identical in both the north and the south, but the temperature in one or the other area, and moisture content are very different fromother.As for the northern hemisphere, here the climate is relatively warm.Upper zone - this Arctic glaciers, where the annual temperature variations are about 25 degrees.In winter, the thermometer drops to the level of 25-30 degrees below zero in the summer rises to + 5-10.The hottest month in the northwest Atlantic is August, coldest - February.Above the northern region formed area of low pressure - Icelandic low.Rainfall here is about 250 mm.In the temperate latitudes of the Northern Hemisphere temperature fluctuations make already 10 degrees.Increases and rainfall of 1000 mm per year.Tropical called Azores High because of the increased pressure.Precipitation here occur mainly in winter, and in summer blow easterly trade winds that carry dry air.In general, in the northern hemisphere of the Atlantic air and water temperatures are much higher than in the South.
southern hemisphere
polar climatic zones of the Atlantic - to the north is the Arctic and Antarctic in the south, and the last, we are now considering.Then there are the maximum annual temperature variations - up to 30 degrees.In the winter frosts are terrible - to -40 Celsius or more, and in the summer the air is heated to just one.The coldest month here is August, and the hottest - February.In the temperate zone temperature fluctuations up to 15 degrees.In the summer here is warm enough - up to 20, and in winter bar thermometer drops to -10.Average rainfall reaches 1500 mm per year.The big difference is observed between the northern and southern tropics.If the above equatorial climate is mostly dry, in the south, due to the fact that the ocean expands, forming a large cloudy.Rainfall here is equal to 1500-2000 mm per year.The oscillations in temperature are greater than one degree.In some areas they constitute 3-4 degrees.
Equatorial Zone
cross the waters of the Atlantic zone of the equator - that is their geography.Atlantic Ocean in this area heats up to a maximum, and, most importantly, is the area's most abundant rainfall and fog.During the year, the air temperature and the water does not immediately change.Precipitation falls mainly in the winter, but in general it rains evenly in every season.Their number is 3000 mm per year.Above the equator in the Atlantic waters are formed mainly in the summer mists.Most of them go to the southern hemisphere, to the elevation of La Plata in Argentina.Those who formed closer to the northeast, called sand fogs.They are formed because of the strong winds that blow from the Sahara.
