Abstract
A relationship between the north–south asymmetry of sunspot formation and the amplitude of 11-year cycles has been established from the RGO/USAF/NOAA data on sunspots. It is shown that the higher the solar cycle amplitude, the smaller the absolute value of the north–south asymmetry. The revealed pattern has been investigated in a numerical dynamo model with irregular variations of the alpha-effect.
