This study includes massively parallel simulation results on droplet collisions in turbulence. The attained maximum Taylor-microscale-based Reynolds number (Re
) exceeds 103
, which steps into the typical range (O(103
)) of observed Re
in turbulent clouds. The results clearly show that the Re
dependence of turbulence enhancement on droplet collision growth is relevant for cloud microphysics modeling. This will promote the discussion on the Re
dependence of turbulent collision statistics.
