This is explained by Copernicus, who largely confirms that the circulation of the Gulf Stream rising towards the North Atlantic is at its weakest point for at least the past thousand years.
Sea surface temperature is a fundamental variable that is used to define and predict the complex interactions between the ocean and the atmosphere. The image shows the sea surface temperature in the North Atlantic Ocean, as measured by the marine environment monitoring service for the European Copernicus remote sensing program. Data refer to March 8, 2021.
In combination with other ocean parameters, sea surface temperature is used to map the history of the Gulf Stream, as well as, from a broader and more complex perspective, the deep currents circulation system with which it interacts, which extends to the whole planet. We are also referring to the circulation of the Atlantic Ocean, whose abbreviation is AMOC.
The thermohaline circulation, also known as the Great Conveyance Belt, extends all over the planet, from the Atlantic Ocean to the Pacific Ocean, and vice versa.
AMOC is one of the major ocean circulation systems that distribute heat, which has a major impact on our planet’s climate.
A recent study published in Nature Geoscience shows that AMOC activity has fallen to its lowest historical levels, due to the impacts of climate change.
However, there are significant changes in the transport of warm waters by ocean currents in Europe. This could aid in the formation of extratropical oceanic cyclones. Indeed, an increase in the intensity of ocean storms, as well as irregularities, has been reported in the past.
This year, strong hurricanes occurred in the North Atlantic at the height of summer, representing a phenomenon of exceptional size.
The impact on Earth’s climate resulting from the weakening of the Gulf Stream, as well as the complex circulation system of AMOC, such as thermohaline circulation, is the goal of climate projection by mathematical models.
They have repeatedly declared the cold of European winter. But on the other hand, we have a general global warming phenomenon that changes the consequences, with expectations already complicated in their own right, and getting unsatisfactory results like reliability.
Will it get cooler next winter? Will they be more snow? Perhaps the most extreme of all, this is the theory that many scientists tend to believe as much as possible.
Certainly, we observe a significant imbalance in European winters that we have not seen before since the presence of data on weather data.
