Ionospheric Irregularities Initiated by Planetary Waves

摘要: The nonstationary process of the accumulation ions meteoric origin, which is caused by propagation planetary waves at altitudes lower ionosphere, considered. Based on horizontal and vertical ion drift in waves, a possibility plasma density increases factor 10–20 comparison with background concentration demonstrated. This takes place areas cyclonic motion scale order 1500 km. connection this subsequent formation midlatitude sporadic layers irregularities producing radio reflections It shown that action origin necessary element scheme occurrence layers.
