Abstract: To prevent disasters and reduce damage, based on the observation data from the meteorological stations of Liuzhou from 1951 to 2016, the variation characteristics of the main meteorological disasters in Liuzhou were analyzed. The results showed that the number of the rainstorm days displayed distinct inter-decadal variation. Most serious rain disasters occurred in the 1960s、 1990s、2000s and relatively fewer occurred in 1970s and 1980s, The average number of rainstorm days was 5.4d, most of them were from April to August , with the most in June; the average number of thunderstorm days was 61.2d; there were more thunderstorm days from March to September. The mean annual wind number, hail days and fog days were respectively 0.5d, 0.1d, and 5.3d. Besides, thunderstorms, strong wind and hail damage showed decreasing trend; fog days generally showed a downward trend, but after 2000, fog days had an increasing trend.
