New insights into the jet stream make better climate predictions possible

Jet 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.

Jetstreams gelten als „Wettermotor“. Es gibt sie auf der Südhalbkugel genauso wie auf der Nordhalbkugel. Die Windströmungen in großer Höhe treiben Hoch-

"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."

What you always wanted to know, especially in summer, but never dared to ask

about jetstream and Rossby waves,

Mike Mann has you covered.
Pub-sci article, written 2019 for the curious like you and me.

Where the curtain folds come into existence, and why – and then, what the folds do with the weather on the ground when they stay locked in place – locked for reasons also explained.

Quantum is also used!! 😁 😁 🖖🏽

The winner (as always) is #Google #Chrome, and many of the other #Chromium powered browsers like #Brave, #Vivaldi, and #Arc manage to keep up.

#Thorium doesn't, probably due to an older version of Chromium, and #Edge is still unusually slow. Edge can't even finish #JetStream.

Surprisingly #Opera has gotten especially slow, though it used to be among the fastest.

"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.

Ocean and atmosphere equally responsible for Atlantic 'cold blob,' scientists find

A 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.
