The ocean conveyor belt and the Gulf stream ocean currents have a direct influence on our lives. They determine our weather, our climate, and much more the ocean currents and wind systems, transport heat from the equator to the poles and operate like a larger engine for the global climate in the oceans.
There are numerous currents. The so-called ocean conveyor belt is very important for our. This term describes a combination of currents that result in four of the five global oceans exchanging water with each other, they form a worldwide circulation system. The conveyor belt is also called the thermohaline circulation with Thermo referring to the temperature.
And Heline to the salt content of the water, both determine the density of the water. While the masses of water may be moved in part by wind. Primarily the different entities of the global oceans are responsible for their movement. Warm water has a lower density and rises. While cold water sinks. The water’s density also increases with a higher salt content at the equator.
The heat from the sun is especially strong, resulting in a lot of evaporation and thus a rise in the water’s salt content. That is where the Gulf stream begins. The Gulf stream is very important for the European climate. Its length of 10,000 kilometers makes it one of the largest and fastest ocean currents on earth.
And it’s very warm at roughly two meters. A second. It brings up to 100 million cubic meters of water per second, towards Europe, a constantly blowing wind. The Southeast trade wind drives warm surface water to the Northwest, into the Gulf of Mexico, where it heats up to 30 degrees Celsius. The turning of the earth and the west winds then direct the Gulf stream towards Europe and split it up.
One part flows south another east to the Canary current. And a third part flows north, where it releases a lot of heat into the atmosphere. As the north Atlantic current, the water becomes colder there it’s salt content and identity rise on account of evaporation. And it drops down between Greenland, Norway, and Iceland.
There we also find the largest waterfall on earth. The so-called Chis, roughly 15 kilometer wide pillars with water falling up to 4,000 meters, 17 million cubic meters of water per second. Or roughly 15 times more water than is carried by. All the rivers in the world. This creates a strong Marom, which constantly pulls in new water and is the reason that the Gulf stream moves towards Europe.
Countless species use the Gulf stream as a means of transport on their trips from the Caribbean to Northern areas, but it doesn’t just bring us animals an enormous quantity of war. Now also comes with it in order to reduce the same heat, which it brings to the shores of Europe. We would need 1 million nuclear power plants.
That’s why we also call the. A heat pump. Without it, the temperature would be significantly colder here, at least five to 10 degrees. Instead of lush fields, we would have long winters and sparse ice covered landscapes in Europe. In the last few years, scientists and pundits in the media have repeatedly expressed the fear that the Gulf stream could come to a standstill due to climate change, because if the polar caps actually melt the salt content in the water off Greenland would fall as would its density.
The north Atlantic current would no longer be heavy enough. And so it wouldn’t sink as usual in the worst case that would bring the Gulf stream, our heat pump to a stop. Some climate experts also assume that climate change could compensate for this effect. We know that it can be normal for the climate to change by looking at the development of the earth over the last few million years, there are ice ages and warm periods.
In the last ice age, a gigantic flood of melting water, crippled the heat, bringing north Atlantic current covering the Northern hemisphere in ice scientists have different views on the impact that climate change will have on the global ocean conveyor belt. But one thing is clear when the climate changes, then the complex system of ocean currents and winds, which has remained fairly stable since the last ice age will change in ways that we don’t yet understand.
