The disturbance phenomena and its characteristics of electromagnetic field are studied in this paper, based on the observational data in satellite and ground station during the magnetic storm occurred from 21 to 23 July, 2009. The results showed that: (1) the synchronous disturbances are seen from the two kinds of electromagnetic data in the same magnetic storm, especially during the active phase. (2)The disturbances performance are different: from electromagnetic data of revisited orbit in satellite, the disturbances of storm and non-storm are distinguished effectively in the main phase stage; the evolution trend of magnetic storm can be found from the data of continuous orbit. The geoelectric and geomagnetism data is a time sequence for a fixed location, therefore the full evolution of magnetic storm can be reflected. (3) The features and advantages of the two kinds data can play a better role, if they are comprehensive applied.
