Generation of Internal Gravity Waves in the Thermosphere during Operation of the SURA Facility under Parametric Resonance Conditions
Abstract
:1. Introduction
2. Problem Statement
3. Problem Solution
- exponentially decreasing cosine ,
- a segment of the cosine with frequency and duration ,
- a periodic sequence of N rectangular pulses. For certainty, we assume that their amplitudes are the same and equal to 1, and the periods coincide.
4. Numerical Estimation
5. Conclusions
- To develop a physical model of a force source and an energy source (possibly significant energy to the upper atmosphere.
- To find the relationship between the amplitude of atmospheric disturbances and the effective power of radio transmitters based on solving the nonlinear problem of waves in the atmosphere with specified localized sources. It is necessary to use a model of the medium with parameters as close as possible to those actually measured at the location of the transmitters (taking into account the wind movements of the medium that change over time and space). Such calculations probably require the use of a supercomputer.
- To analyze the possibility of solving the inverse problem: to restore the parameters of the atmosphere (possibly sources) from the measured space-time characteristics of disturbances.
