| الوصف: | The method of correlation functions of signal amplitude and phase fluctuations (CFAF) was used to process fluctuations that were numerically obtained for different standing MHD waves in a flat rectangular resonator. It has been established that the CFAF dependences on the average fluctuation phase shift (τ) always look like a periodic peak train. The interval between two adjacent peaks depends on the first harmonic frequency of one of the possible one-dimensional resonator standing waves and is determined using the universal formula. In the proposed method, processing results in measured values of this frequency. In addition, the CFAF method was for the first time used to process magnetic field variations in a range of periods from 0.5 to 6.0 s. The distribution functions of the first harmonic periods have been experimentally obtained for Borok (Φ = 53.9°, Λ = 114.3°) and Mondy (Φ = 46.7°, Λ = 173.6°) observation stations. It was established that all of the characteristic values of these periods completely correspond to the periods of known standing MHD waves in the plasmasphere and at its boundary. |
