| Zusammenfassung |
| Multi-platform and multi-sensor observations are employed to investigate the
impact of mineral dust on cloud microphysical and precipitation processes in
mesoscale convective systems. For a given convective strength, small
hydrometeors were more prevalent in the stratiform rain regions with dust
than in those regions that were dust free. Evidence of abundant cloud ice
particles in the dust sector, particularly at altitudes where heterogeneous
nucleation of mineral dust prevails, further supports the observed changes
of precipitation. The consequences of the microphysical effects of the dust
aerosols were to shift the precipitation size spectrum from heavy
precipitation to light precipitation and ultimately suppressing
precipitation. |
