Scientists have debunked the myth of the relation between solar activity and climate change
Source:The North Atlantic oscillation (NAO) or periodic large-scale climate changes in the Northern hemisphere of our planet do not depend on solar cycles. To such conclusion came from a team of American and canadian scientists, tried to find a direct link between these two phenomena. The findings of researchers from the Earth Observatory Lamont-Doherty, faculty of engineering of Columbia University and their colleagues was in the journal Nature Geoscience. Press release research portal Phys.org.
The North Atlantic oscillation or the oscillation is a natural phenomenon of the redistribution of atmospheric mass between the Arctic and the subtropical Atlantic. It is characterized by a change in atmospheric pressure at the sea surface, affects the strength of the winds and is associated with the formation of hurricanes, their intensity and amount of precipitation. Oscillation also affects how severe will the winter in Europe. During the last years it was believed that these climate changes depend on 11-year cycles of solar activity. Based on this assumed correlation some scientists have tried to predict weather conditions for decades to come.
Climatologists Gabriel Chiodo, Jessica Arleen, Lorenzo Polvani from Columbia University in USA, and their colleagues decided to test whether this relationship exists. With the help of available meteorological data and climate models, they were able to prove that this opinion is erroneous.
The Study showed that prior to 1960 no evidence of correlation between NAO and solar cycles did not exist. However, after 1960, the researchers observed a weak correlation, which, according to the researchers, is due to a random coincidence due to internal variability in the climate system and cannot be used to predict weather conditions in the future. The use of complex climate models have also shown that fluctuations apparently depend on internal atmospheric changes, not solar activity.
"the Variability of North Atlantic oscillation on decadal scales, it may occur naturally, without external drivers in addition to the interaction of ocean and atmosphere," the scientists say.
The Authors hope that the scholars who wrote about the connection between solar activity and NAO will try to challenge their conclusions.
"it's pretty simple. We are seeing quite an interesting sociological bias towards a certain opinion about the climatology. Some of our colleagues believe that climatic variations are somehow triggered from the outside. They agree that the climate is periodically subject to change by himself, without the influence of external factors driving these changes. We hope that these scientists will be able to argue the conclusions of our work. After all, it is science" — total climatologists.
