England: An unusually long winter is caused by the sun's activity

Scientists working at Met Office Hadley Weather Forecast Center, UK, said: The sun's 11-year operation cycle has caused unusually prolonged cold weather during the last two winters. over in the UK.

The results of this study were published in Nature Geoscience.

This study is based on computer simulations of what will happen: when the stratospheric temperature is higher than in the tropics, then lower it under the influence of ultraviolet radiation. purple, and the way in which this normal, cooler stratosphere creates a change in creating cold winds that cover the lower troposphere in the northern hemisphere.

"It is the lowering of the sun's activity in recent times (the past two winters) that has affected the air in the upper layer of the atmosphere, creating a cold winter wind that covers the area. Northern Europe, " scientists said.

"Although there are many factors such as the melting of glaciers and the El Nino phenomenon, which have affected unusually prolonged cold weather during the past 2 winters. Measurements (from satellites) of ultraviolet radiation in high-level atmospheres have shown that the low intensity of the sun in recent times has played a major role in causing abnormal phenomena. on " , according to Sarah Ineson, a climate scientist at the Met Office Hadley Weather Forecast Center, England.
