Modulated high-frequency radio frequency heating of the ionospheric F region produces a local modulation of the electron temperature, and the resulting pressure gradient gives rise to a diamagnetic current. The oscillations of the diamagnetic current excite hydromagnetic waves in the ELF range that propagate away from the heated region. The generation of the waves in the 2–10Hz range by a modulated heating in the midlatitude ionosphere is studied using numerical simulations of a collisional… CONTINUE READING
