To address these knowledge gaps, we investigated the impact of ambient temperature on global dispersal of COVID-19. The relationship between daily confirmed cases of COVID-19 and meteorological conditions (temperature and humidity) was studied using the data of approximately 3,750,000 global confirmed COVID-19 cases. Section 2 briefly introduces the data and the methods used in this paper. The results and the discussion are presented in Section 3 and the conclusion is presented in Section 4.
