[...] Paul Beckwith has a masters degree in laser optics, which he has somehow parlayed into being a “Climate System Scientist” to spread alarmism about the climate system.
But his post “Unprecedented, Jet Stream Crosses Equator” suggests he knows little of meteorology, let alone climate.
A “jet stream” in the usual sense of the word is caused by the thermal wind, which cannot exist at the equator because there is no Coriolis force. To the extent that there is cross-equator flow at jet stream levels, it is usually from air flowing out of deep convective rain systems. That outflow often enters the subtropical jet stream, which is part of the average Hadley Cell circulation. [...]
There is frequently cross-equatorial flow at jet stream altitudes, and
that flow can connect up with a subtropical jet stream. But it has
always happened, and always will happen, with or without the help of
humans. Sometimes the flows connect up with each other and make it look
like a larger flow structure is causing the jet stream to flow from one
hemisphere to the other, but it’s in no way unprecedented.
