                         (GDI) applicable for horizontal wavelengths longer than 10 km in 
                         the E region is presented. By analytically solving the non-local 
                         differential equation for the polarization potential, analytical 
                         forms of the dispersion relation and growth rate, hosting new 
                         contributions from non-local effects, are obtained. The new growth 
                         rate and the amplitude of polarization potential are examined for 
                         a wide range of wavelengths that reveal the positive growth of GDI 
                         for wavelengths of 25 km. These characteristics raise the 
                         possibility of the formation of unstable structures of vertical 
                         size 2030 km in the upper E region, often observed during twilight
