Responses and Periodic Variations of Cosmic Ray Intensity and Solar Wind Speed to Sunspot Numbers

Figure 2

Cross-correlation coefficients of daily SSN-CRI and SSN-SWS for the two solar cycles 23 and 24, separately. The abscissa designates the time delay with respect to the daily sunspot numbers. (a) SSN-CRI solar cycle 23. (b) SSN-SWS solar cycle 23. (c) SSN-CRI solar cycle 24. (d) SSN-SWS solar cycle 24.
