Abstract
According to the data on the 20–24 solar activity cycles, long-term variations in the annual average solar wind speed and interplanetary scintillation index are compared to Wolf number variations. It is shown that the scintillation parameters at mid- and high heliolatitudes exhibit a slow nonmonotonic trend with a characteristic scale of the order of the secular cycle. For long-term data series since 1610 to the present, the correlation of variations of Wolf numbers and air temperature anomalies is analyzed. The possible application of the results to the global climate problem is discussed.
