      abstract     = {Enhancement of the binary homogeneous nucleation rate of
                      H2SO4 and H2O and condensation of H2O and HNO3 on liquid
                      sulphate aerosol particles due to mixing processes in the
                      tropopause region were investigated by conducting
                      theoretical studies and by using a section aerosol box
                      model. If two air parcels with a large initial temperature
                      and humidity difference are mixed with each other the
                      nucleation rate within the resulting air parcel will be
                      enhanced. This is due to the curvature of the saturation
                      vapour pressure curve. The theoretical studies show that in
                      the tropopause region enhancements of the nucleation rate of
                      up to five orders of magnitude can occur. Since the mixing
                      causes strong supersaturations also the condensation rate
                      will be enhanced, especially for HNO3. The simulation with
                      the sectional aerosol box model shows that after the mixing
                      of two air parcels up to 40 $wt\%$ of HNO3 is taken up by
                      the smallest aerosol particles. Since the initial air
                      parcels are initialized with 0 $wt\%$ HNO3 this corresponds
                      to a very strong enhancement. Measurements during the STREAM
                      1998 campaign show,, an entrainment of stratospheric air
                      into the troposphere during the flight on 15 July leading to
                      a production of new particles. Box model studies reproduce
                      fairly well the measured number of newly formed particles.
