Based on observing data of aerosol number concentration and meteorological parameters in December 2017 in Nanjing, the diurnal variations and differences of 10~1000nm nanometer aerosol spectra were compared and studied in sunny and fog-haze days. The results showed that there was a significant relationship between the occurrence of unimodal distribution and pollution aggravation, which occurred in the sunny afternoon, haze serious pollution and pollution dissipation stage, and dense fog process, respectively. The peak particle sizes were sunny days (20~100nm), haze days (27~144nm) and foggy days (34~122nm). Under three weather conditions, strong solar radiation and low humidity in sunny days were suitable for the generation of small particles, and the proportion of nuclei mode was the highest in sunny days. The meteorological field in haze days was suitable for the stable existence of a large number of particles, and the proportion of Aitken mode was highest in haze days. A large amount of aerosols had hygroscopic growth in foggy days, resulting the proportion of accumulation mode was highest in foggy days. During the pollutant accumulation phase in haze days, the collision and growth effect of a large number of accumulated particles on nuclei and Aitken particles inhibits the generation of nuclei and Aitken particles. The variation rate of nuclei and Aitken mode particles concentration was -91.0% and -62.5%, while that of the accumulation mode particles was 89.7%. Fog removal was most effective on Aitken particles.
