The results indicated that the meteorological factors were significantly correlated and contributed 35.7% of the variation in the bioaerosol microbial activity (sig. = 0.000). Specifically, temperature had a significantly positive influence on bioaerosol microbial activity (sig. = 0.000), whereas RH and wind speed were negatively correlated (sig. = 0.020 and sig. = 0.034). Some differences exist between our results and those of previous studies. This may be because of different regional environments. However, we confirmed that the meteorological factors were important factors in the variation of microbial activity in bioaerosols.
