【 摘 要 】

To explore the temporal characteristics of atmospheric visibility in Haikou city, the capital city of Hainan Province, based on the monitoring data from 1957 to 2016 (60 years), the characteristics of atmospheric visibility were analyzed. The results showed that:1) The average atmospheric visibility in 1957-2016 was 18.89 km and the trend was 0.16 km/decade; 2) the highest atmospheric visibility appeared in the summer and the lowest appeared in the winter, while the mean values of atmospheric visibility monitoring in spring and autumn were closer; (3) the rate of atmospheric visibility of "good" (> = 20km) and "poor" (
