Because the available water is spread among more particles, the cloud droplets that form in the ships' wakes are smaller than typical Marine layer cloud droplets.
同时，因为它们是小液滴和冰晶形成需要的凝结核，因此尘埃微粒还能在云微物理学层面给云层带来改变。
Aerosols also affect cloud microphysics because they act as nuclei around which water droplets or ice forms.
