The solar cycles are most widely known

The solar cycles are most widely known for their cyclical variances in the number and the size of sunspots that occur. The sunspot number, which is a composite index, can reach to several hundred at the peak of the cycle and fall to zero during the minimum period of the cycle when at times no sunspots occur at all. 

It has been recognized that these long-term cycles of the Sun, spanning 11 years on average, affect the climate on Earth, and with it affect agriculture to the point of affecting commodity prices.
