• The aim of our studies was to examine turbulent, wavy structures in noctilucent clouds taking into account the clouds dusty plasma nature.

• However, the dusty plasma nature of noctilucent clouds has been neglected.

• We consider a weakly ionized dusty plasma composed of electrons, singly charged ions, negatively charged dust grains and neutrals.

• Dustier layers appear to be deposited during periods when the atmosphere is dustier.

• The transitions and the self-gravitational effects on the surface dust-ionacoustic mode are investigated in semi-bounded magnetized dusty plasmas.

• The study of dusty plasmas is of significant practical use and scientific interest.

• The dusty plasma aspect has been widely neglected, so far.

• However, they all neglect the dusty plasma aspect.

• In dusty plasmas, the electron-neutral collision frequency is typically much smaller than the electron g yrofrequency.

• The effect of an exter nal magnetic field on an ion-dust two-stream instability in a collisional dusty plasma is investigated.

• We are dealing with isothermal low-frequency (with respect to the dust g yrofrequency) dynamics in partially ionised dusty plasmas that are in ionisation equilibrium.

• Thus, in this paper we investigate the effects of dust grain rotation on the surface dust-acoustic wave in a semi-bounded dusty plasma.

• A lot of research work is being carried out in the area of dusty plasmas due to its applications in space, astrophysics and laboratory plasmas.

• The equations are then used to investigate decay and modulational instabilities in magnetized dusty plasmas.

• To summarize, we have investigated the influence of an exter nal magnetic field on dust charge perturbations in a dusty plasma.
