In the model described in my 2009 paper, (available here on this blog in the 2009 section) I predicted that a global equatorial rotation of the liquid core relative to the mantle, as being the driving force in the dynamo that creates the earths magnetic field. Not the opposite as some theorists believe. This rotation of the liquid core is driven by the inner core rotating faster or slower than the mantle. I proposed that the solid cores relative speed to the mantle varies over large time scales and when it's relative speed to the mantle changes from faster to slower or vis a versa, this reverses the dynamo mechanism which in turn reverses the magnetic field polarity. Hence long term flipping of the earths magnetic field can be explained. I also proposed that the solid inner core is malleable and can change shape over time from extended in the north south axis to flattened in the north south axis. As is understood with angular momentum, this action leads to any rotating body slowing down or speeding up its rotation speed. Hence when the solid core is stretched north south, it rotates faster than the mantle. As is observed currently and explained in more detail in my 2009 paper. Further to this I proposed that the solid core also wobbles as it spins. Leading to an off axis solid core. As my paper points out, current evidence suggests that the solid core is not only spinning faster than the mantle but also tilted off axis as it spins. Analogous to a spinning top that wobbles. And recent research has indicated this tilt to be currently at about 10 degrees off the earths north south axis with the north pointing at 10 degrees towards Siberia. In my paper I predicted this off axis core would create an off axis equatorial flow in the liquid core which in turn would create an off axis magnetic field. And that the field would be diametrical opposite to the off axis solid core. Which is also observed. The core currently points 10 degrees to Siberia and opposite to that in Canada, at roughly the same latitude is the magnetic North Pole. However at the time of the writing of my paper I assumed the speed of the wobbling solid cores' north and southern tips were the same as the overall rotational speed of the solid cord. Which is about 0.1 degree a year faster than the mantle eastwards. Hence I a predicted eastwards flow in the liquid core. Also by inference my model predicts the strongest speeds of the liquid core should be at the top and bottom stretched ends of the solid core, as they ascribe a circular path around the north and south poles of the earths rotational axis. (This is best explained visually by the video simulation I posted concurrently with the paper in 2009, the URL being available from the earlier post of this paper on this blog). Being closer to the mantle than any other part of the solid core they will induce the largest speed differential in the liquid core. Very much as the rotating blades of a mixing machine will have the fastest liquid rotation speeds nearest the blade ends itself.
The recent Livermore et al paper has confirmed all these predictions in my paper. Both unique and original predictions in 2009 and now. Most if not all other theories incorrectly assume convection.
The Livermore paper confirms a high speed liquid core flow centered above Siberia at 10 degrees off axis from the earths rotational polar axis exactly as my 2009 paper predicts. However, with one important caveat. The assumption in Livermore’s paper is a westward flow of the outer part of liquid core
This initially seems to rule out my model because although my model has accurately predicted most of the rest of the Livermore papers conclusions, his westward flow seems to contradict my models overall predicted eastward flow.
However on analysis, I realise now, that Phil has misinterpreted the westward movement of Earths dipole magnetic field with a westward flow of the liquid core near the mantle. In other words he hasn’t observed a westward flow of the liquid core. He has used satellite data showing anomalies in the earths field at those latitudes. And then made assumptions about core flow directions. Based on the flawed convection model. A model which is not only fundamentally different from my model. But to date has been consistently unsuccessful in all of its predictions made by various theorists over the decades.
