33 SURFACE PRESSURE AND SUNSPOT CYCLES

What the mainstream is missing. An excellent read.

reality

Even in summer we see a marked trough in surface pressure on the margins of Antarctica, a product of polar cyclone activity driven by differences in the ozone content of the air and resulting differences in air density. Of course, the contrast  between the coldness of the ice bound continent and air from the mid latitudes also helps but at 200 hPa where these cyclones are generated the contrasts seen at the surface are less apparent. Surface contrasts probably assist in allowing the upper air troughs to propagate to the surface but where they don’t exist in Arctic summer the propagation from upper air troughs generated by ozone to the surface still occurs.

In winter atmospheric pressure increases in the mid latitudes of the southern hemisphere increasing the differential pressure between the mid latitudes and 60-70° south. Surface pressure over Antarctica hits a planetary maximum.
