Short summary

Agglomeration of ice and dust particles in the mesosphere are studied, using classical electrostatic approaches which are extended to capture the induced polarisation of surface charge. The instances of strong attraction between particles of the same sign of charge are predicted, which take place at small separation distances and also lead to the formation of stable aggregates.
