Why are there ocean currents and what are them?

Ocean currents are divided into three types according to their causes: wind-sea currents, density currents, and compensation currents.

Wind-sea currents are the phenomenon of large areas of sea water flowing in one direction due to a stable wind direction, such as the equatorial warm current, which flows under the blowing of trade winds.

The North Atlantic Warm Current flows under the blows of westerly winds in the westerly wind belt.

Density flow is the direction of directional flow of seawater due to different sea surface heights due to different sea densities, such as density flow between the Mediterranean Sea and the Atlantic Ocean (due to the high evaporation of the Mediterranean, high salinity, high sea water density, and lower water surface than the Atlantic Ocean, resulting in the flow of water from the Atlantic Ocean into the Mediterranean Ocean in the upper layer due to the high density of sea water in the lower Mediterranean).

The compensation current is formed by the subsidence of the seabed or the flow of surrounding seawater after the seawater in the area has flowed away for various reasons, such as the Peruvian cold current, which is formed by the warm current of the southern equatorial current in the Pacific Ocean flowing from the eastern Pacific Ocean to the western Pacific Ocean under the blowing of trade winds.

On the one hand, there is the wind, which blows the ocean currents; On the one hand, there is the difference in temperature and salinity. The ocean currents are very large, such as the two largest warm currents, the Kuroshio Current and the Gulf Stream, the Kuroti Current is more than 200 times larger than the largest Amazon River (Amazon River = Nile River + Yangtze River + Mississippi River), and the Gulf Current is twice as large as the Kuroshio. So sometimes there is the phenomenon of icebergs, icebergs headwinds.

The formation of ocean currents is simply the wind-sea current and the density flow! One is formed due to the wind and the other is due to the different density of the seawater!

There are three types: 1. Density flow due to the difference in salinity.

2. Jujube stuffiness due to the wind and sea currents formed by the monsoon.

3. Ocean currents formed due to temperature differences, 5, three causes. 1. Wind and sea currents: formed by the blowing of prevailing winds.

Such as the equatorial warm current of the low latitude mammothic fiber in the northern and southern hemispheres, and the last one, what is the lowest sea area? Density? Salinity branch imitation?

Temperature? 2. It is formed under a variety of factors such as prevailing winds, geostrophic deflection forces, and terrain obstruction; Among them, the prevailing wind predominates, 0,

The directional flow of seawater, the world's oceans include several major ocean currents.

Also known as ocean current, in addition to the tidal movement caused by the gravitational force, the large-scale flow of seawater along a certain path in the ocean.

Ocean currents, also known as ocean currents, are the large-scale flow of seawater along a certain path in the ocean, in addition to the tidal movement caused by the gravitational force. The factors that cause the movement of ocean currents can be wind or the uneven distribution of sea density caused by the thermohaline effect. The former is manifested as wind stress acting on the sea surface, and the latter is manifested as a horizontal pressure gradient force in seawater.

Combined with the geostrophic deflection force, the seawater flows horizontally and vertically.

Ocean currents are the main regulators of the thermal environment on the Earth's surface. Ocean currents can be divided into warm currents and cold currents. If the water temperature of the ocean current is higher than the water temperature of the water reaching the sea area, it is called a warm current; If the water temperature of the ocean current is lower than the water temperature that reaches the sea area, it is called a cold current.

Generally, ocean currents flowing from low latitudes to high latitudes are warm currents, and ocean currents flowing from high latitudes to low latitudes are cold currents.

In addition to the tidal movement caused by the gravitational force, the large-scale flow of seawater along a certain path in the ocean current. The main driving force that causes the movement of ocean currents is wind, and it can also be the uneven distribution of sea density caused by the thermohaline effect. The former is manifested as wind stress acting on the sea surface, and the latter is manifested as a horizontal air pressure gradient force in seawater.

Combined with the geostrophic deflection force, seawater flows both horizontally and vertically. Among them, the prevailing wind is the main driving force of the wind and sea currents. Due to the blocking and frictional effects of the coast and the seabed, the behavior of ocean currents near the coast and near the seafloor is very different from that in the open ocean.

Ocean currents refer to the flow of seawater in the ocean, also known as ocean currents, and the flow of seawater from high temperature areas to low temperature areas.

The large-scale flow of seawater along a certain path is also called ocean current.
