    Abstract: The linearized dynamics of the idealized narrow neutral cells at high latitudes in the absence or presence of auroral energy impulse of the type q0 e-at is discussed in the upper atmosphere. The general expression for the oscillation amplitude ∆z of the cells is given by ∆ z=q0 [e-at – cos (ω t) + a sin (ω t)/ω)]/(a2 + ω2) + ν0 sin (ω t)/ω Here ν0 ... Show More
