Of all the mysteries that we have on this planet, one that stood out for centuries, is what is it that really affects our weather? As more and more research on the subject took place, this mystery of how the ocean's currents affect our weather has solved, and thus providing an understanding as to why they do.

As warm water makes it's way to the North from the Gulf Stream it becomes denser, and begins to drop to the lower levels of the ocean.
This cold layer of water begins to push South into the South Atlantic, and as it does, the salt content adds to the density, as the ice that forms in the sea takes up a good amount of water, leaving the salt behind that normally would be part of that volume of ice to increase the density of the water, and continues to add to the process.

Our oceans are constantly moving in many ways, as they are pushed by heavy winds as evident by the waves they cause, and is also pulled by tides which are influenced by the gravitational pull of the moon, as it makes it's way around the world somewhat like a giant conveyor belt. The rotation of the earth also has a direct influence on the ocean currents as they move clockwise in the north, and then counter clockwise in the south.

The density of the cold water is what can be considered a major part of that conveyor belt, and as it moves along, it in time will surface once again in the Pacific Oceans. The warming of the water begins once again, and this then makes its way back to the Atlantic. This process of warm to cold, cold to warm, as it makes its way around the world, is why Europe in general, has a milder climate.

When the Gulf Stream pushes east across the Atlantic, it splits into three directions, which would be into the Norwegian sea, "Sargasso Sea," and makes it's way towards the coast of Europe, which is how those who live in England for example, enjoy higher temperatures than many other countries in the same latitude.

Because of these constant changes in water temperature, each part of the world is affected according to how warm or how cold the current is when it reaches any particular part of the world. What is normally a balmy climate can change drastically by the water temperature which in turn generates changes in weather patterns that will cause such climate changes.
