Periods of extreme cold winter weather and perilous snowfall, similar to those that gripped the UK in a deep freeze with the arrival of the 'Beast from the East', could be linked to the solar cycle, pioneering new research has shown.
A new study, led by Dr Indrani Roy from the University of Exeter, has revealed when the solar cycle is in its 'weaker' phase, there are warm spells across the Arctic in winter, as well as heavy snowfall across the Eurasian sector.
The research is published in leading journal Scientific Reports, a Nature Publication, on Tuesday, 20 March 2018.
Dr Roy, form Exeter's Mathematics department said: "In spite of all other influences and complexities, it is still possible to segregate a strong influence from the sun. There are reductions of sea-ice in the Arctic and a growth in the Eurasian sector is observed in recent winters. This study shows those trends are related and current weaker solar cycle is contributing to that."
The new study observed that during periods when the winter solar Sunspot Number (SSN) falls below average, the Arctic warming extends from the lower troposphere to high up in the upper stratosphere. On the other hand there is a cooling when SSN is above average.
It explored how the 11-year solar cycle - a periodic change in the sun's activity including changes in the levels of solar UV radiation and changes in the SSNs - can be linked with the Polar vortex and Arctic Oscillation phenomenon, which affects winter Arctic and Eurasian climate.
It subsequently can influence weather conditions in Europe, including the UK, Scandinavia and Asia.
'Solar cyclic variability can modulate winter Arctic climate' is published in Scientific Reports.

And Landscheidt's work becomes further validated...

Character assasination is the mainstreams go-to for trying to subdue new ideas, so nice form...

Again with the character assasination, you guys really need to pull your head out of the mainstreams ass

Yes, I was always told it was humans... Interesting

The changes inflicted by humans, add a small positive effect to the baseline temp each and every year. While this amount is usually 1/20 or even less than the amount added or subtracted by natural variability, it accumulates over time. The amount added in the last 20 years is easily the amount we will see in natural variability ever. In the next 50 years this will accumulate far past the effects of any of the cycles described.

2007 was warmer than the year before and the year after, and is part of a steeply increasing trend.

22 citations is not exactly numerous. Three are to his own work, which is of questionable quality. One, published in the "Abstract Volume 9th International Congress of Biometeo-rology," is titled "Cycles of solar flares." Exactly how many biologists and meteorologists are qualified to review a paper on solar physics? Was it peer-reviewed at all? It looks as if he showed up at a conference and presented a paper, so they were obliged to publish it afterwards. Several other references are to Scientific American and "3ient. American" (presumably the same publication) which is not a peer-reviewed journal (and which specializes in dumbing down recent scientific advances for a general audience). Some of the other references are obscure books and low-impact journals.
