The SABER temperature data permitted determination of the upward propagation characteristics of the FK (E1) waves with propagation speed in the range of 4 km/day.
The occurrence rate of tweeks with the propagation distance in the range of 1000 5000 km during equinox, winter, and summer seasons varies about 92, 89, and 92 %, respectively.
Tweeks with the propagation distance in the range of 1000 2000 km occurred more often during summer as compared to those during equinox and winter.
Tweeks with m = 4 8 occur more often during summer season as compared to winter and equinox seasons.The occurrence rate of the tweeks with the propagation distance in the range of 1000 5000 km during equinox, winter, and summer seasons are 92, 89, and 92 %, respectively.
Across the single runs, different initializations of weights of the back-propagation algorithm in the range of [−0.1,0.1] were used.
Observing tweeks at a low-latitude station, Kumar et al. (2008) reported that 90%% of tweek propagation distance are in the range of 1000 5000 km with maximum in the range of 2000 3000 km.
According to the shadowing radio propagation model, the evaluation are carried out in indoor visible conditions, so the value of radio propagation model should be in the range of 1.6 1.6.
We focus on wave propagation in the frequency range of 0.1 0.5 Hz considering characteristic ground motion amplification in the target area and the signal-to-noise ratio of signals obtained by the seismic interferometry.
An estimate of the upward propagation velocity yields a value in the range of approximately 4 km/day.
According to the shadowing radio propagation model, the parameter should be in the range of 1.6 1.8, so we change in the range with the step of 0.05.
