The presence of noctilucent clouds and world-wide rainfall anomalies is attributed to the formation of secondary particles from meteor vapors. These particles are formed by coagulation of meteor vapors and are subject to horizontal and vertical displacement by a Lorentz force and the gravitational force of the earth. Adsorption of water vapor by the surfaces of anhydrous secondary particles followed by adsorption of nitrogen (II) oxide in the D-layer is assumed to be the primary mechanism of production of positively charged particles. The increase of the residence time of the secondary particles in the vicinity of 80 km, due to rapid decrease in particle settling velocity and the consequent increase in particle concentration and the action of the Lorentz force on positively charged particles are assumed to cause formation of noctilucent clouds. The variable time lag between the appearance of meteor showers and corresponding rainfall anomalies is attributed, primarily, to the time of settling of sharply defined concentration profiles of coagulating particles through the 80-40 km layer.
