  • In the present work, variations of ionospheric Total Electron Content (TEC) are investigated and compared with applying Empirical Orthogonal Functions (EOF) on the dataset from the Global Ionospheric Maps (GIMs) which are produced by Jet Propulsion Laboratory (JPL) over two concerned areas: the North America (30°N-50°N, 140°W-50°W) and East Asia (42.5°N-57.5°N, 65°E-140°E). The first three EOF components attribute about 99.57% and 99.79% to the total variations separately, and spatial-temporal features manifested by each EOF components are similar for the two areas: the first order EOF component for both areas represents semiannual variation which is strongly modulated by the solar activity; the second order component exhibits pronounced east-west longitude difference to the zero valued geomagnetic declination line, and these east-west longitude differences are coincidently consistent with plasma drift velocity caused by thermospheric zonal wind; the third order component demonstrates latitudinal variations possibly influenced by plasma drift velocity caused by thermospheric meridional wind. Results of the this paper are useful for understanding the physics mechanism of the ionospheric variations.
