60 year-old wind pattern changes in stratosphere
An anticipated wind pattern in the stratosphere recently changed in a way unwitnessed in the past 60 years. Usually, stratosphere winds circulate the Earth in alternating easterly and westerly directions over a 28-month period, termed “quasi-biennial oscillation”. However, this pattern changed from late 2015 till July 2016. Scientists believe climate change due to global warming caused the change.
