The role of a complex (positive) ion composition in the wind‐shear theory of sporadic‐ E layers is investigated. The vertical drift velocIty used is the classical one derived from the “slab” approximation, and it is almost the same for all the different ions. In the new model, with a mixture of positive ions, the limitation of the maximum density of the layers by recombination is much less serious than it was in the old model with a smgle positive ion. Two special cases are studied: the first is concerned with meteoric ions, and it is shown that very thin rectangular layers may occur if the total amount of these ions is sufficient; the second case involves the ions NO + and O + 2 , and in this case it appears that large amplifications of electron density at the layer maxima could easily be accompanied by relatively small reductions at the minima.
