                         the ionospheric plasma with thickness less than 5 km occurring in 
                         heights from 90 to 150 km. At equatorial and low latitude regions, 
                         Es layers cause a scattering of radio waves at HF frequencies. 
                         Thus, their detection and occurrence characteristics can be 
                         analyzed from ionosonde observations. The Es layers are classied 
                         in several types in relation to the formation mechanism according 
                         to the region of the globe where they are detected. At low and 
                         middle latitudes, the Es layer formation depends essentially on 
                         the vertical wind shear associated with the tidal winds. In 
                         several data for Brazilian region, it was observed the h type Es 
                         with downward movement until lower altitudes. This behavior for 
                         the low latitude is still not everything known. Therefore, in this 
                         work, we used the Ionospheric Model of the E Region (MIRE) with 
                         the purpose to identify the atmospheric physic dynamics of the Es 
                         layer movement at latitudes around the Equatorial Ionization 
                         Anomaly in the Brazilian sector. The new results about the 
                         simulations and data will allow explaining the semidiurnal and 
                         diurnal periodicity that characterizes the Es layer downward
