Zhang et al: Consistent Long-term variation in the hemispheric asymmetry of solar rotation | Tallbloke's Talkshop

My thanks to Astrophysicist Ian Wilson for flagging up this new paper from Zhang, Mursula and Usoskin. This sheds some light on the periodic changes in the rate of rotation of the latitudinal bands on the solar surface, and the correlated changes in the number, size and hemispheric location of sunspots. It turns out there is an anticorrelation between the two solar hemispheres. In other words, when rotation rates are high in the north, along with sunspot roduction, they are lower in the south, and vise versa. There are nuances that modify this relationship, and this leaves scope for further study. The periodicity is given as 80-90 years, and this frequency is potentially linked to planetary periods such as the Double inner solar system cycle, the half Jose cycle and Uranus’ orbital period, which falls in the middle of the range.   [Thank goodness Gavin Schmidt's Fortran climate models allegedly correctly handle all sunspot factors along with millions of other variables and all their interactions, all without knowing the initial state of each variable!]

Flashback: Remember when we almost spent $45 trillion based on some secret Fortran code written by left-wing idiots with no common sense?

The equations are written in Fortran, a computer language that is, as Dr. Schmidt puts it, "very old and not very trendy." The computer code is 126,327 lines, to be exact

Flashback: Climate Sensitivity Reconsidered

The climate is “a complex, non-linear, chaotic object” that defies long-run prediction of its future states (IPCC, 2001), unless the initial state of its millions of variables is known to a precision that is in practice unattainable, as Lorenz (1963; and see Giorgi, 2005) concluded in the celebrated paper that founded chaos theory
