Reaction of the high-latitude lower ionosphere according to the data of the medium wave facility of partial reflections located at the radio physical observatory “Tumanny” (69.0N, 35.7E) of the Polar Geophysical Institute and the geomagnetic field near the place of observation by data of the observatory Loparskaya (68.6N, 33.3E) to explosions of Siberian meteors are considered. The first meteor has blown up on 5 March 2014 at 7:29 the Yakut time (on 4 March 21:29 UT) in the sky over the Vilyuysk district of Yakutia (64.3N, 123.1E). Witnesses observed the flight of the meteor which has ended with a bright flash and a loud clap. The second considered meteor has blown up on 6 December 2016 at 18:37 the Krasnoyarsk time (11:37 UT) in the area located between settlements of Bogoslovka, Sizoi and Cheryomushki (52.9N, 91.4E). For the analysis amplitudes of ordinary and extraordinary waves and the electron concentration received by the data of the partial reflections radar and the geomagnetic field data of the observatory Loparskaya have been considered. It was shown that the explosions had caused in the ionosphere appearance of the waves of different types: acoustic-gravity waves, slow MGD-waves, and also change in the geomagnetic field.
