~We must remember December 2019 boxing day all time in recorded history low temperature at center of Polar Vortex.
~As a matter of prognosis, the recent overwhelming stable wider area of warming in 24 hour darkness had a side effect, a smaller area of stable cooling.
~The center of Polar Vortex: the Cold Temperature North Pole will be at the N.P.
~Sun disk observations have shown remarkable early spring warming Northwestwards from center of Canadian Arctic Archipelago, why is this strange and unusual?
~2020 Vertical sun disk slight expansion numbers changes past 2 years all time low compressions numbering nil.
~ENSO variations closely resembles vertical sun disk expansion data
Et tu ENSO?
2020 Summer La Nina or El-Nino? Is the big question. The usual excellent NOAA updates and analysis suggest a neutral summer again. There has been very peculiar no La-Nina rebound since very warm 2016 El-Nino. What we know is that a La-Nina favors dryer air colder winter, as opposed to El-Nino creating more clouds (the cloud seeding theory) giving a cooler summer but warmer winter. However, the evidence on ENSO variations from afar can be observed. In the Arctic (and elsewhere) El-Ninos give much higher sliver clouds making spectacular twilights. Again, I observed both types this late winter, none or few black or white wafer thin high altitude clouds, varying from week to week. This indeed suggests a Neutral ENSO is coming. But there is another way to indirectly observe ENSO trends:
