Hello,
I just realized that the earth also has differential rotation, just like the sun.
As you know the sun has differential rotation of plasma by latitude, the earth has a similar differational rotation for solar plasma that leaks into the magnetosphere forming plasmoids, and these earth trapped plasmoids move eastwards at a rate that is slower than the sun's by latitude.
"Leaks" is a poor term, that plasma is forced into the magnetosphere by competing magnetic field strengths.
For the sake of argument let us assume that solar plasma leaks into the magnetosphere based on its magnetic field in oppostion to magnetosphere magnetic field strength by latitude. Since the magnetic field strength is stronger the higher the latitude the, the higher the latitude the stronger the plasmoid needs to be to force itself inside the magnetosphere.
This is the exact same thing we see in the sun's butterfly pattern of sunspots. A new soalr cycle means the sun is running through more dense instellar plasma and the stronger plasma can leak into the sun's heliosphere at higher latitudes. As the interstellar plasma diminishes and weakens it enters the sun's heliospehere at lower latitudes.
Since plasma is steered by magnetic field strength interstellar plasma density would have a regular pattern giving the sun regular cycles and patterns. (11-Schwabe, 22-Hale, 70-100-Gleissberg, 210-Suess, 2,300-Hollstatt, 6,000-Xapsos, etc). When interstellar plasma density variation compounds in minima or maxima you have long term complex solar variation, and long term earth climate and geologic variation.
On the sun you get sunspots, on the earth you get climate and earthquakes, events triggered by solar plasma discharge (and if not discharge knock on effects of the presence of plasama). On the sun you have interstellar plasmoids affecting the surface of the sun, and conversely solar plasmoids affecting the surface of earth.
sunspot-earthquake, CME-volcano
I believe if you almost double the differential rotational rates of the sun by latitude you will get the earth based plasmoid differential rotation.
This is why earthquakes seem so hodge-podge in timing in response to geomagnetic storms.
Take the solar storm of February 15th in which a plasmoid entered the magnetosphere at ~42 degrees north latitude and ~90 degrees longitude. It than began its eastward trek at the correct speed for that latitude, encountering the first tectonic fault two days later and discharged causing this earthquake;
CHINA-RUSSIA-NORTH KOREA BORDER
Magnitude 6.7 Mw
Location 42.561N 130.835E
This same plasmoid will take ~12 days to run into northern California San Andreas fault, and then ~26 days to reach the mid Atlantic ridge fault. It will follow the manetic field gradients of that latitude.
When the interstellar plasma discharges on the sun you get sunspots, when solar plasma discharges on earth it is because it has better grounding over a tectonic fault and we get earthquakes. This means that sunspots are a result of trapped interstellar plasma finding a better solar grounding point.
This accounts for all the scaling and timing issues.
