Extreme Heat, Weather Conditions Attributed to Stagnant Jet Stream
Stagnant jet stream keeps high, low pressure systems stuck. ‘Devastating’ heat domes across the globe are connected
It’s no coincidence that extreme heat is engulfing huge swaths of Asia, Europe and North America all at the same time.
But right now, the carousel isn’t moving. It’s been cemented in place for weeks, and forecasts show it’s going to stay that way.
Blame the jet stream — the “meandering river of wind that encircles the globe and creates our weather,” as climate scientist Jennifer Francis puts it.
Meanwhile, the low pressure systems are wreaking their own havoc as rains pour down.
In India, months of blistering heat has given way to a deluge that has led to widespread damage. Floods are threatening Beijing and Tianjin in China, and two weekends in a row have brought deadly flooding to the US Northeast.
