Cross-correlation of solar wind parameters with sunspots (?Long-term variations?) at 1 AU during cycles 21 and 22

Long-term variations of solar wind parameters at 1 AU are correlated with sunspots for the time interval 1973 to 1993 (solar cycles 21, 22). Using the Near-Earth Heliosphere Data `OMNI' the plasma density, the magnitude of the interplanetary magnetic field, the solar wind velocity and the solar...

Description
Summary:Long-term variations of solar wind parameters at 1 AU are correlated with sunspots for the time interval 1973 to 1993 (solar cycles 21, 22). Using the Near-Earth Heliosphere Data `OMNI' the plasma density, the magnitude of the interplanetary magnetic field, the solar wind velocity and the solar wind temperature show consistent long-term variations in each cycle (21 and 22)--pointing to specific time-lags in the coupling between sunspots (and the underlying convection zone), the solar corona and the solar wind parameters at 1 AU (ecliptic).
