More Evidence On Equatorial Crossing Jet Streams // Published on Jul 7, 2016

In a recent video I showed the northern hemisphere (NH) jet stream crossing the equator and merging with the Southern Hemisphere (SH) jet stream.


Here I show many recent examples of NH troughs merging with SH crests, and vice versa.  I argue that the root cause is very rapid Arctic temperature amplification, due to exponentially declining sea ice and spring snow cover.


As jet stream behaviour becomes more erratic, extreme weather events will continue to worsen, with escalating societal costs.  The sad thing is that this is so unnecessary.
