      abstract     = {A theoretical framework was constructed by which one can
                      estimate the relative role of different processes in
                      thedynamics of atmospheric nucleation mode particles. The
                      framework relies on 14 timescales that describe (1) changes
                      inthe total nuclei number concentration, (2) changes in the
                      mean diameter of the nucleation mode and (3)
                      concentrationsof low-volatile vapours responsible for the
                      growth of nuclei. The magnitude of the derived timescales
                      can be calculatedrelatively easily from the available
                      measurement or modelling data. Application to the
                      lower-troposphere revealed thatunder most conditions removal
                      of nuclei is dominated by their coagulation with larger
                      background particles and thatthis process competes very
                      strongly with growth of nuclei to sizes relevant to
                      atmospheric chemistry and physics.Withsome exceptions,
                      self-coagulation of nuclei was shown to be of marginal
                      importance compared with their growth bycondensation and
                      their removal by coagulation. Finally, by comparing
                      predictions based on relevant timescales withthose obtained
                      from detailed numerical simulations, quantitative criteria
                      were derived concerning (1) when one mayneglect
                      self-coagulation of nuclei when looking at nucleation mode
                      dynamics and (2) when the whole nucleation modecan be
                      neglected because of its eventual removal. These criteria
                      are extremely useful for atmospheric modellers whoneed to
                      simplify their models as much as possible. From the
                      modelling point of view, other processes requiring
                      furtherattention are the introduction of new nuclei into the
                      system and decrease in nuclei number concentration due to
                      dilutionof the air.},
