I am skeptical of your lower chart, as I am now convinced that the polar vortex this time is rising up from the SOUTH Pole. As evidence to support my claim, the past week has been the coolest I have ever seen since I started living in Jakarta 25 years ago. In the wee hours, the temperature gets all the way down to 70F.
Some attribute this to the incessant rain; mayhaps they are not aware of the (S)PV phenomenon.
For the past three days here in the States, the only MSM weather coverage we have had about your neighborhood is from the Australian Tennis Open.
108 degree temperatures, players fainting from the heat, and, apparently, the entire continent is on fire, except for the Tennis Stadium.
I think the MSM became REALLY embarrassed when all those Antarctic ice breakers got frozen in place during the warmest month of your year.
Consequently, we now see non-stop photos and videos of burning homes, dead livestock, and pictures of thermometers.
