                         generating mechanism of poorly studied equatorial plasma 
                         irregularities known as equatorial quasiperiodic echoes. Employing 
                         a two-dimensional model of the collisional interchange 
                         instability, the simulations are able to reproduce the spatial 
                         periodic features of this kind of irregular structures. The usage 
                         of an instability seeding source considering an overlap of two 
                         gravity waves with different wavelengths was capable to produce 
                         such quasiperiodic structures. The results suggest that the 
                         penetration of the equatorial plasma bubble fringe fields in 
                         typical altitudes of the valley region may be the physical 
                         mechanism responsible for the structures. Additionally, the 
                         simulation results indicate that the lower wavelength gravity wave 
                         dominates over the quasiperiodic nature of the these 
                         irregularities. The simulations results present considerable 
                         agreement with radar and in situ measurements of these 
                         quasiperiodic structures.",
