Abstract—Based on data from a system of oblique sounding radio paths at mid-latitudes in the Asian Russia, a high (up to 40–50%) average daily probability of medium-scale traveling ionospheric disturbances in years of moderate solar activity is revealed. The daily variation in the probability of recording these disturbances has a pronounced seasonal dependence. For the winter season, there is a daytime maximum probability that reaches 100% on some days. During the summer season, the maximum probability falls on the nighttime hours of local time at the midpoint of the corresponding path. A possible reason for this is the transition from the winter to summer atmospheric circulation system.
期刊介绍：
Geomagnetism and Aeronomy is a bimonthly periodical that covers the fields of interplanetary space; geoeffective solar events; the magnetosphere; the ionosphere; the upper and middle atmosphere; the action of solar variability and activity on atmospheric parameters and climate; the main magnetic field and its secular variations, excursion, and inversion; and other related topics.
