Solar cycle length vs Temperature


Solar cycle length (red) vs Northern Hemisphere temperature (blue) (Stauning 2011).The number of sunspots has a minimum and a maximum. The solar cycle length can be found in two ways. Either as the difference between two successive dates on which the number of sunspots show a minimum or as the difference between two successive dates on which the number of sunspots shows a maximum. The first number is indicated in the legend as “min-to-min” and the second as “max-to-max” in red color.The temperatures on the minimum dates and the maximum dates are indicated in the legend as “min-to-min” and “max-to-max” in blue color.
