    Abstract:

    The spatiotemporal distributions of aerosols and their transition to cloud droplets are a key issue in studies of clouds and precipitation and climate change. The properties of vertical distribution, size distribution and origin, as well as their transition relationships with cloud condensation nuclei (CCN) and cloud droplet number concentration are investigated using nine flights of aircraft measurements under clear and cloudy conditions in Shanxi, Central Northern China. Results indicate that the structure of atmospheric boundary inversion layer has an important impact on the vertical distributions of aerosols and CCNs. The size distributions under different weather conditions are similar in the upper atmospheric layers but different at lower levels. The high correlation between aerosols and CCNs can be found in vertical. The linear relation of y=1.3x-616.3 can be found between aerosols and cloud droplets with a determination coefficient of 0.96, and transition rate from aerosols to cloud droplets may reach 47%. The linear relation of y=1.6x-473.8 can be found between CCNs and cloud droplets with a determination coefficient of 0.96, and transition rate from CCNs to cloud droplets may reach 69%.
