摘要：

The monthly mean hourly values of total electron content data obtained at Lunping Observatory (geographic coordinates 25.00 degrees N, 121.17 degrees E; geomagnetic coordinates 14.3 degrees N, 191.3 degrees E) by using the ETS-2 satellite beacon signal during the period from March 1977 to December 1990 have been used to analyze the solar cycle Variations of total electron content (TEC) around equatorial anomaly crest region in East Asia. Positive correlations were found between the 12 month running average of monthly mean TECs and sunspot numbers. BY using the linear regression analysis method, the contour charts for real diurnal and seasonal variations of TEC at certain sunspot numbers were constructed and described. The diurnal variation of TEC was represented by the sum of its diurnal mean and first three harmonic components. The Solar cycle variations of these components have also been discussed.
