Synchronization o fgeomagnetic and ionospheric disturbances on the substorm process background A study o f time behavior for the Solar wind concentration shows that in the time period up to 00.45 UT (+3 GMT Kazan) its higher values are observed with a further decrease and reaching the minimum value at 01.00 UT. For the interval 01.00 - 02.00 UT, there is a general increase in the Solar wind velocity, which persists throughout the interval. foF2 critical frequecy Time, UT Figure 1. Wavelet spectra of F2 layer critical frequency (the first panel from the top) and geomagnetic field H component (secondpanel) for September 3,2014. The black arrows indicate a correspondence between the spectra maximums for foF2 and the H component disturbances. fofl critical frequency (Kazan) Figure 2. Wavelet spectra of the ionospheric layer F2 critical frequency and interplanetary magnetic field Bz component disturbances for September 3, 2014. The arrows indicate areas of the spectral singularities coincidence for foF2 critical frequency and IMF Bz component. 98
