    Abstract:

    Based on the cold wave events happened in Wuhan during 1996 to 2004,this article analyzes the variation of the ionospheric electronic density TEC and the correlations between TEC and ground temperature,TEC and ground pressure before and after the transit of three cold wave events.The results show that TEC fluctuates in different degrees and completes an increase then decrease process in 2-3 days before the cold wave transit;TEC decreases evidently on the standard day of the cold wave;and TEC possesses a variation in M form in 5 days after the cold wave transit.Some positive or negative correlations exist between TEC and ground temperature,TEC and ground pressure before and after the transit of cold wave.
