This paper examines the variations of the scale height at the F2 layer (Hm) for disturbed conditions in the mid-latitude ionosphere. The data base includes Hm values derived from ionograms recorded by digisondes located at: Pruhonice (50.0°N, 15.0°E), Ebro (40.4°N, 0.3°E) and El Arenosillo (37.1°N, 353.3°E). The data covers disturbed periods during the years 2000 and 2001.The behavior of other parameters derived from the electron density profiles such as the thickness parameter B0,and the ionospheric slab thickness  are also analyzed (EST). As a measure of the ionospheric disturbance during the storms the relative deviations of the parameters from the corresponding monthly median values have been calculated. All the parameters present changes during the storms. In general, increases during the main phase and first stage of the recovery phase are observed. The relative deviations of Hm, EST and B0 present similar temporal behavior
