“…One can observe that additional terms substantially modify the patterns. Now, the smallest modulation occurs in the intermediate seasons, which is in accord with observations of the first SR frequency: the thunderstorms "spread" over the globe during the intermediate seasons (Nickolaenko and Rabinowicz, 1995;Nickolaenko et al, 1998). Figure 3b shows the modulation factors L 1 and L 2 against the local time.…”

“…In addition we compare our data with conclusions by based on a different source model. One might use, say, the single point source model (Yatsevich et al, 2006) for the purpose, or the model of three global thunderstorm centers (Nickolaenko et al, 1998) and synthesize the necessary "experimental" data set. Clearly, the model data should be realistic, therefore, we use the following approach.…”

Abstract.We extend the technique suggested by Sentman and Fraser (1991) and discussed by , the technique for separating the local and universal time variations in the Schumann resonance intensity.Initially, we simulate the resonance oscillations in a uniform Earth-ionosphere cavity with the distribution of lightning strokes based on the OTD satellite data. Different field components were used in the Dayside source model for the Moshiri (Japan, geographic coordinates: 44.365 • N, 142.24 • E) and Lehta (Karelia, Russia, 64.427 • N, 33.974 • E) observatories. We use the extended Fourier series for obtaining the modulating functions. Simulations show that the algorithm evaluates the impact of the source proximity in the resonance intensity. Our major goal was in estimating the universal alteration factors, which reflect changes in the global thunderstorm activity. It was achieved by compensating the local factors present in the initial data. The technique is introduced with the model Schumann resonance data and afterwards we use the long-term experimental records at the above sites for obtaining the diurnal/monthly variations of the global thunderstorms.

“…Nickolaenko et al [1998] found that the source area of the global lightning activity also plays an important role affecting the SR frequency variation. We conducted additional simulations (not shown), in which we changed the magnitude of the lightning activity at the three lightning centers, as well as the area and positions of these three lightning centers.…”

[1] The diurnal and seasonal variations of Schumann resonances (SR) have been reported in a number of experiments. In this paper, a three-dimensional FDTD model of the Earth-ionosphere cavity with a day-night asymmetric conductivity profile is employed to study the diurnal and seasonal variability of the power and frequency of the first Schumann resonance (SR) mode. Comparison of the FDTD results and recent experimental measurements shows a clear modulation in the SR power related to the local ionospheric height and global lightning activity. It is found that SR frequencies are not only a function of the local time but also are controlled by the global lightning activity changing with universal time.

“…The common approach to this problem is based on the preliminary assumption of the spatial lightning distribution. The most widely used approaches are the models of the three thunderstorm centers-Southeast Asia, Africa and South America [20,[70][71][72][73][74], and a single thunderstorm center traveling around the globe [35,75,76]. An alternative approach is placing the receiver at the North or South Pole, which remain approximately equidistant from the main thunderstorm centers during the day [38].…”

Lightning produces electromagnetic fields and waves in all frequency ranges. In the extremely low frequency (ELF) range below 100 Hz, the global Schumann Resonances (SR) are excited at frequencies of 8 Hz, 14 Hz, 20 Hz, etc. This review is aimed at the reader generally unfamiliar with the Schumann Resonances. First some historical context to SR research is given, followed by some theoretical background and examples of the extensive use of Schumann resonances in a variety of lightning-related studies in recent years, ranging from estimates of the spatial and temporal variations in global lighting activity, connections to global climate change, transient luminous events and extraterrestrial lightning. Both theoretical and experimental results of the global resonance phenomenon are presented. It is our hope that this review will increase the interest in SR among researchers previously unfamiliar with this phenomenon.
