The relationship between the atmospheric condition of the polar mesosphere and the formation process of noctilucent cloud particles are discussed. The result suggests that the very low temperature found frequently in the summer polar mesosphere not only enables the noctilucent cloud particles to grow by water vapor condensation but also the nucleus to form through the ion-induced nucleation.
