Distinct changes of cloud microphysical properties and height development by dust aerosols from a case study over Inner-Mongolia region

Dust aerosols, by serving as cloud condensation nuclei and/or ice nuclei, can impact the properties and development of clouds. Selecting dust event occurred in May 2016 a case, this study investigates potential impacts aerosols on system examining differences between polluted unpolluted parts using geostationary satellite (Himawari-8) observation data. It is found that particles effective radius (r e ) significantly smaller region than region. With increase aerosol optical depth (AOD), particle r decreases, showing first indirect effect (IE) value (defined − dln AOD CWP 0.31.
