                         has been carried out using data recorded by digital ionosondes 
                         installed at S~ao Jose dos Campos (23.21S, 45.86W, dip angle: 
                         -37.07, dip latitude: 20.69S), and Jata (17.9S, 51.7W, dip angle: 
                         -25.16, dip latitude: 13.21S). In this study, statistical survey 
                         of the types of Es layers at latitudes of the Equatorial 
                         Ionization (EIA) and South Atlantic Magnetic (SAMA) anomalies were 
                         obtained during the months that represent dierent seasonal periods 
                         (April, June, September and December of 2016). The results 
                         revealed the manifestation of four dierent types of Es layers ( 
                         at/low, cusp, high and slant), in which the at/low type was the 
                         most frequent over both stations. In order to investigate the main 
                         mechanisms acting to the generation of the Es layers, we used the 
                         Ionospheric Model of the E Region (MIRE). Tidal winds parameters 
                         estimated from Meteor Radar observations at Cachoeira Paulista 
                         (22.42S, 45.0W, dip angle: -36.98, dip latitude: 20.63S) are used 
                         as input to the MIRE model aiming to investigate tidal waves in 
                         uence in the formation of these Es layers. The vertical proles of 
                         ionospheric plasma density estimated by the MIRE are compared with 
                         the electron density obtained using the blanketing frequency 
                         parameter (fbEs) deduced from ionograms registered in the analyzed 
                         regions. In general, the results show that the values computed by 
                         the MIRE are in good agreement with the observational data for the 
                         Es layers, in which it is conrmed that the Es layers formed near 
                         both anomalies have a strong in uence of the wind shear
