Investigation of medium-scale traveling ionospheric disturbances over the Asian region of Russia during solar cycle 24

Using data of the network of chirp sounding radio paths at middle and subauroral latitudes of the Asian region of Russia, we investigated peculiarities of manifestation of medium-scale traveling ionospheric disturbances (MS TIDs) over the Asian region of Russia during solar cycle 24. Typical seasonal dependencies and daily variations in probability of MS TID occurrence and their registration time on one hop radio paths of different directions have been revealed.
