摘要/Abstract

摘要：

Ionograms taken from a Digisonde Portable Sounder (DPS-4) at Zhongshan Station of Antarctica in 1995 are used to analyse the mean ionospheric properties in winter. The F region is rather unstable in winter and has large diurnal variation. The monthly medium value of ƒ_oF₂ has a main peak around 0900UT when maximum value occurs and a sub peak between 1300-1500UT. It may be affected synthetically by the low energy electron precipitation in cusp region, the high latitude plasma convection and the solar radiation, resulted in so called F region magnetic noon phenomena. Low values of ƒ_oF₂ occur in post midnight (2000-0100UT) when Zhongshan Station crosses the ionospheric polar hole. Sporadic E layer which caused mostly by auroral particle precipitation can be observed almost every day with the highest value of ƒ_oE₂ around 1700UT. The diurnal variation of E layer is relatively smooth.
