Abstract

The temporal and spatial distribution of scintillations accompanied with Total Electron Content (TEC) depletions, scintillations with no TEC depletions, and TEC depletions with no scintillations are discussed. The data of ionospheric scintillation and TEC from January 2011 to December 2012, and from January 2015 to December 2015 are observed by the monitor setting at Shenzhen GPS station. The results show that these three types of events occurred mainly in spring and autumn. These three types of events occurred mainly from 19°N to 23°N, 21°N to 24°N and 24°N to 26°N, respectively. In addition, these three types of events occurred mainly from 20:00LT to 22:00LT, 21:00LT to 23:00LT, 22:30LT to 23:30LT, respectively. The temporal and spatial distributions of these three types of events are responsible for the evolution process of equatorial plasma irregularity over South China.
