Abstract: According to data of the network of ionosondes situated about 1500—3100 km from the place of meteorite “Chelyabinsk” fall, ionospheric disturbances at an altitude of about 300 km are analyzed. The meteoroid's fall was accompanied by the generation of gravitational waves in the neutral atmosphere and of travelling ionospheric disturbances. The velocity of the travelling ionospheric disturbances was about 600—700 m/s, the period was 70—135 min, and the amplitude of relative disturbances of electron concentration reached 10—20 %. Wave disturbances with a relative amplitude of electron concentration of 10—20 % which could be caused by long-living whirlwinds in the top atmosphere were observed during 6—7 hours. |
