Sažetak
We presented an analysis of the geoeffectiveness of corotating interaction regions (CIRs)employing the data recorded from January 2008 to December 2014. For this purpose we made a list of 283 solar wind (SW) disturbances incorporated into an online catalog for general use. After we separated solar wind signatures on: CIRs, interplanetary coronal mass ejections (ICMEs), interactions and complex signatures ; we focused our attention on 173 CIRs (61% of all SW signatures) where the stream interface (SI) was clearly recognizable. Furthermore, we analyzed in detail the correlation of solar wind parameters in different parts of CIRs, particularly in front and behind of SI, with changes in geoeffectiveness. In this analysis, in most events (95% of the analyzed CIRs) weak increas e of Dst index occurs between forward shock and SI, while the main decreases of Dst index occurs between SI and reverse shock of CIR. The correlation coefficients between Dst index and the magnetic field B, proton density Np, flow speed v and proton thermal speed vth, in the region behind the SI are: cc = 0.72, 0.62, 0.45 and 0.64, respectively. Correlations for region between forward shock and SI are ignificantly lower.
