The ionosphere is disturbed by various natural phenomena. Of interest is thunderstorm/lightning as it produces very low frequency (VLF) discharges which can be used to study the ionosphere behaviour. Thunderstorm is dominant in the equatorial low latitude regions and coastal areas. By using differential total electron content (DTEC) derived from Global Navigational Satellite Systems (GNSS), thunderstorm effects on the ionosphere have been studied. In this study, we deploy a similar GNSS approach to observe ionosphere response at different times of the day during thunderstorm in the Southern China coastal area. The results show that DTEC of about ±1.5TECU was observed during both daytime and nighttime. The daytime ionosphere response which is similar to that of other areas is deemed as significant. In contrast, the nighttime response is about twice as large as that of other areas. This indicates that the nighttime response to thunderstorm is quite significant in the Southern China coastal area as compared to other regions.
