Abstract This paper is concerned with the ionospheric irregularities produced during daylight hours in mid-latitude regions by medium-scale travelling ionospheric disturbances (MS-TIDs) as these disturbances pass overhead at a recording station. These irregularities are detected as ionogram trace distortions as well as by spread-F conditions particularly related to the second-hop reflections of HF radio waves. The existence of a significant amount of spread on second-hop ionogram traces during the passage of two particular MS-TIDs is illustrated and discussed. Experimental evidence is presented to suggest that, similar to the results for night-time spread-F, the occurrence of these daytime events is inversely related to variations in the neutral-particle density of the upper atmosphere, for the annual and sunspot-cycle variations. However, the results do not show a similar inverse relationship for the diurnal variation.
