Changes in the Jet Streams Causing Simultaneous Heat Waves Across the Globe. By Leslie Hook.

“The jet stream is the leading driver of our weather,” said Paul Williams, professor of atmospheric science at the University of Reading in the U.K. “The jet stream is like a conveyor belt, delivering storms to us one after the other.” …

Right now, a global pattern of five big waves is circling the world, leading to simultaneous heat waves across continents. This pattern, known as wavenumber 5, can persist for weeks, causing hot areas to stay hot for a long time. …

The jet stream itself appears to be changing its behavior over the long term and slowing down in summer …

 

 

We kind-of predicted this back in 2015, when we predicted that global cooling would start in 2017 (in the event, the warming peak was 2016), and suggested this mechanism that Stephen Wilde proposed:

1940 – 2016: The jetstreams are more east-west, and don’t move as far towards the equator:

 

 

2016 – 2030? The jetstreams are more north-south, which generates more clouds (which reflect more of the Sun’s light back out to space, and thus cool the planet) as the moving air masses rub against each other:
