Ocean Current General Knowledge

▬ The flow of a large amount of ocean water for a very long distance in a certain direction is called ocean water stream. This stream is of two types – hot stream and cold stream.



▬ Warm water stream: Water streams flowing from the tropics to high temperate and subipolar tropics in low latitudes are called hot streams. It often moves from the equator towards the poles. The temperature of their water is higher than the temperature of the water en route. Therefore, these currents increase the temperature in the areas where they run.

▬ Cold water stream: The stream flowing from high latitudes to low latitudes is called cold water stream. They often move from the poles towards the equator. Their water temperature is lower than the temperature of the incoming water. Therefore, these dharas reduce the temperature in the areas where it runs.

▬ Northern Hemisphere streams flow to its right and Southern Hemisphere streams to its left. It is caused by the effect of cariolis force.

▬ The only famous exception to the general system of transmission of ocean currents is found in the northern part of the Indian Ocean. In this section the direction of flow of currents changes with the direction of monsoon wind. Warm streams flow towards the cold seas and cold streams flow towards the warm seas.

▬ Warm water currents of Pacific Ocean:
1. Northern equatorial stream
2. Curioso’s Stream
3. Northern Pacific Water Flow
4. The Strait of Alaska
5. Alanino Stream
6. Sushima’s Stream
7. South Equator
8. East Australian waters
9. Reverse equatorial stream

▬ Cold water currents of Pacific Ocean:
1. Curile equatorial stream
2. Humboldt or Peruvian waters
3. California’s watershed
4. Antarctica watershed

▬ Warm waters of the Atlantic Ocean:
1. Northern equatorial stream
2. Brazil stream
3. Gulf Stream Stream
4. Reverse equatorial Guinea
5. Florida Stream
6. Derminger water stream
7. D. equatorial water stream

▬ Cold Water Mercury of Atlantic Ocean:
1. Labrador’s waters
2. East Greenland Stream
3. Vanguella’s stream
4. Antarctica Stream
5. Canary Stream
6. Falkland Stream

▬ Warm and stable water currents of the Indian Ocean:
1. South Equator
2. The stream of Agulhas
3. Mozambique

▬ Cold and Sustainable Water Streams of the Indian Ocean: Waters of Western Australia.
Note: The summer monsoon stream of the Indian Ocean is a hot and variable stream and the winter monsoon stream is a cold and variable stream.

▬ Gas Sargasso sea: An area of calm and stagnant water in the North Atlantic Ocean between 20 ° to 40 ° northern latitudes and 35 ° to 75 ° western longitudinal streams, known as Sarangaso Sea Is known. It is a calm water zone located between the circle of Gulf Steam, Canary and Northern equatorial streams. Thick sea grass floats on its banks. This grass is called Sargassum in Portuguese, after which it is named Sarangaso Sea. Sarangasam are rootless grasses. The Sargasso Sea area is about 11000 sq km.

▬ Sarangaso Sea was first seen by the sailors of Spain.

▬ Sarangaiso Sagar is recognized as an ocean desert.

▬ Gulf Stream and Labrador waters meet near Newfoundland, Grand Bank is located on Newfoundland, a famous place for marine fishing.

▬ Where the hot and cold streams meet, grass called plankton is found, due to which the fishery industry has developed highly at that place.

▬ Due to the hot stream of curio Shiva near Japan and the cold stream of Oyo-Shiva, there is a dense foggy shade there.

Tide

▬ Tides: The rise and fall of ocean water due to the attractiveness of the moon and the sun is called tide. Rising above sea water and moving forward is called ebb and ebb.

▬ The tidal-producing force of the moon is twice that of the Sun, because it is closer to the Earth than the Sun.
On the new moon and full moon, the moon, sun and earth are in a straight line. Hence high tide is produced on this day.

▬ The Saptami or Ashtami of both the sides make the Sun and Moon right-angled at the center of the Earth, in which case the attraction forces of the Sun and the Moon become ineffective in attempting to balance each other. Hence low tide is produced on this day.

▬ Tides after 12 hours 26 minutes per day on every place on earth and 6 hours 13 minutes after tides.

▬ The tides come twice daily, once due to the attraction of the moon and the second time due to the centrifugal force of the earth.

▬ Normally the tide comes twice daily, but in South Chatter on the south coast of England, the tide comes four times a day. Here the tides reach the various channels through the English Channel and twice through the North Sea.

▬ The average daily temperature of ocean surface is negligible (about 1 ° C).

▬ The highest annual temperature of ocean water is marked in August and the lowest annual temperature in February.
