New insights into the #jetStream make better #climate predictions possible
Researchers uncover how climate change impacts the “weather motor”

eurekalert.org/news-releases/1 #science #climateCatastrophe

EurekAlert!New insights into the jet stream make better climate predictions possibleJet streams are often referred to as the “motor” of global weather: High-altitude wind currents steer areas of high and low pressure, playing a crucial role in shaping our weather.  However, how these atmospheric flows are affected by climate change remains uncertain. Now, a team of climate scientists from Leipzig University, working with other research institutions, has developed a new method that enables a deeper understanding of what is referred to as the Eddy-Driven Jet in the Southern Hemisphere. This advance paves the way for more accurate predictions in the coming years about how this wind belt may respond to climate change.

"50% of the observed shift in the Southern Hemisphere's #jetstream is directly attributable to #globalwarming . The other half is caused by a combination of other climate-related changes. These include the warming of the upper tropical atmosphere, the strengthening of the winds in the stratosphere and the warming of the tropical Pacific. While some of these factors are also influenced by anthropogenic #climateChange , others are more difficult to attribute."

"The cold blob can disturb the atmospheric #jetstream and storm activities, so it has implications for #extremeweather events in North America and Europe," said Laifang Li, assistant professor of #meteorology and atmospheric science at Penn State.

phys.orgOcean and atmosphere equally responsible for Atlantic 'cold blob,' scientists findA patch of the Atlantic Ocean just south of Greenland is cooling while much of the world warms. The origin of this "cold blob" has been linked to weakening ocean currents that help regulate global climate—called the Atlantic Meridional Overturning Circulation (AMOC). A team of scientists led by Penn State has found a weakening AMOC impacts not just the ocean but also the atmosphere, and that these two factors may contribute equally to the cold anomaly.

Rauch von Waldbränden in #Kanada hat am Wochenende für ungewöhnlich orangefarbene Himmelsphänomene über dem Vereinigten Königreich gesorgt.

Die Partikel in der #Atmosphäre streuen blaues Licht, sodass Rot- und Orangetöne dominieren. Die #Rauchwolken wurden durch den #Jetstream über den #Atlantik transportiert.
