Conservation of the angular momentum implies that any change in the total angular momentum of the liquid outer core must be reflected in the angular momentum of the solid mantle (and partially solid inner core) and hence in change of the LOD.

From the geomagnetic data it is inferred that any anomaly in the CAM is propagating from the equatorial to polar region and that this is reflected in the time-latitude CAM / LOD lag as shown in the Fig. 2.

It is said that the total CAM (sum from all individual cylinders) is at a 15-year lead with respect to LOD.

1.      If an event happens in any of cylinders from 4 to 13 (latitude 44-68 degrees) than it would be reflected in the LOD with no delay.

2.      If an event happens in any of cylinders from 18 to 20 (latitude 0-30 degrees) than it would be reflected in the LOD with a 22.5 year delay.

3.      If an event happens in the polar cylinder No.1 (latitude 78-90 degrees) than it would be reflected in the LOD with a 7.5 year delay. 

Are the statements in  1, 2 and 3 correct ?
