In scientific circles the Pacific Ocean is often calledGreat and this is due to a number of reasons. Firstly, because its waters wash the boundaries of the five continents. In the west, the shores of Eurasia and Australia adjoin it, in the east the coast of the continents of the Americas, and in the south the borders of Antarctica. In other words, the ocean extends on both sides of the equator. Secondly, about half of the area of the World's water area is exactly the Quiet. Thirdly, this ocean is the deepest and warmest. In its depths originate giant wind waves and tropical hurricanes, which sometimes have destructive effects. And, finally, the bottom of the Pacific Ocean has a diverse relief, consisting of underwater ridges, mountain chains. Therefore, on the surface of this particular ocean, the largest number of islands is concentrated.
In the thickness of the Pacific Ocean, different currents are formed.This is due to winds that sweep over the water surface of the reservoir with the difference in pressure. They circulate in such a way that they form two complete circles in the northern and southern hemispheres. A number of warm currents circulate in the depths of this ocean, which are called so because their temperature is greater than the temperature characteristics of the surrounding waters. Surface currents of the Pacific Ocean are also present, but in a smaller amount. They arise because of the influence of the western and trade-wind air masses on the surface of the ocean.
Kuroshio or the Japanese current is washing the boundariescoast of Japan from the south and east. This name acquired the current because of the dark blue hue of its waters. It is formed due to the difference in water levels of the East China Sea and the corresponding part of the ocean. The warm current of the Pacific described above redirects the water currents of the South China and East China Seas, which are warm and salty, to the northern latitudes, thereby making their climate milder.
Already in the north-eastern part of this oceanAlaskan current is formed. It flows from the south into the Alaskan Gulf, goes north and turns south-west. Then, passing the Aleutian Islands, it flows into the Bering Sea.
East-Australian warm current of the PacificIt was not by chance that the ocean got a similar name. After all, this water flow is the most extensive off the coast of New Zealand and the eastern shores of Australia. Because of this current, the climate on the coasts is tropical. That is, warm and humid weather prevails.
In addition to the above, the warm currents of the Pacific Ocean are the Northern Pacific and Southern Equatorial.
The Northern Pacific Current takes place atnorthern shores of the water area. It is obtained as a result of combining the currents of Kuroshio and Kuril. This water mass extends from the boundaries of the Japanese islands to the coast of North America.
South Passet or Southern Equatorial Warmthe Pacific Ocean is so named because of the winds that make it up. Namely, this circulating water flow arises from winds-trade winds blowing from east to west. The current originates at the border of the shores of South America closer to the Galapagos Islands and advances to the western borders of New Guinea and Australia. Then it branches. One branch of water is turned to the east. This warm current of the Pacific Ocean in its second part passes into the East Australian current.
In addition to the warm currents in the depths of the Pacific Ocean, cooler water circulation also forms.
The California current, which is not only cold, but also shallow, extends in the northern part of the ocean. It ishes the coast of California in a direction from north to south-west.
The Peruvian cold current of the Pacific is also called the name of Humboldt. It is also superficial and shallow. There is a current near the western part of South America in the region of Peru and Chile.
The Pacific Ocean still has a cold currentCromwell. It is considered a subsurface, and got its name due to the American oceanographer, who discovered the current in one of his expeditions.
The Kuril Current or Oyashio originates inThe depths of the Arctic Ocean and the Pacific coast from the north-west. This water flow determines the climatic conditions of Kamchatka and Chukotka. The current stretches along the coasts of Kamchatka, the Kuriles and the Japanese islands. Its waters are rich in stocks of fish and other seafood.
Таким образом, во многом от того, какие oceanic currents are located near the shores of the continents, their climate and natural diversity depends. As they carry cold and warm waters, and thus affect the temperature on the continents and the amount of precipitation.
