We continue our investigation (see for instance, Yermolaev Yu.I., Yermolaev M.Yu. Statistical relationships between solar, interplanetary, and geomagnetic disturbances 1976-2000, Cosmic Research, v.40, N 1, p.1-14, 2002) where we study 25-year sets of solar X-ray observations, measurements of plasma and magnetic field parameters in the solar wind and Dst index variations with the purpose of revealing the factors rendering the greatest influence on development of magnetospheric storms and thier variations in two solar cycles (1976-2000). Value of correlation (about 40%) between large solar phenomena (strong solar flares and halo-CMEs) and magnetic storms practically does not exceed a level of correlation of random processes. Furthermore it was not possible to find out any dependence between importance of solar flares and value of magnetic storms. The most geoeffective interplanetary phenomena are magnetic clouds (MC) which, as many believe, are interplanetary manifestations of CMEs and compressions in the region of interaction of slow and fast streams in the solar wind (Corotating Interaction Region, CIR). On the average the parts of magnetic storms with Dst < -60 nT generated by MCs and CIRs are equal about 1/3 (for strong storms with Dst < -100 nT the part from MCs is 1/2) and they change along solar cycle: number of storms from MCs have 2 maxima per cycle (during start of rising and start of declining phases) and storms from CIRs have 2 maxima during end of rising and end of declining phases. This work was partially supported by the following grants: RFBR 02-16182, 02-02-17160 and 03-02-17474, and French-Russian scientific cooperation program (PICS grant APIC0090 and RFBR grant 00-02-22001).
