4.0Solar Dipole Divided by Sunspot Number for Following Maximum3.53.02.52.01.51.00.5204521 22 23 24 72165R 240.01965 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015As a measure of the solar polar field we take the absolute difference between the Northand South polar fields in the WSO standard 3’ aperture, using MWO averaged into theWSO aperture and scaled to fit WSO [for 1976-1982] before the start of the WSOobservations. A ‘polar field cycle’ can be defined from one reversal to the next [roughlyfrom solar maximum to the next solar maximum]. The ‘run’ of the polar field values fromeach polar cycle is then divided by the ‘size’ [Rmax] of the next sunspot cycle If thepolar fields were controlling Rmax, this procedure would make all the so normalizedpolar cycles look alike. The above plot shows the normalized polar cycles in dark blue.For the latest polar cycle [from 2000 to 2013] we don’t know Rmax for cycle 24, so wedivide by representative guesses [45, light blue; 72, dark blue; 165, pink]. Our prediction[72] would be the divisor that makes the latest polar cycle most like the other ones.------------------------------------15014013012011010090807060F10.7 Radio Flux (@20UT)2005 2006 2007 2008 2009 2010 2011Daily values of the F10.7 cm radio flux at 20 UT.
