Abstract: Under the background of climate change, the meteorological disasters occur much frequently. The study aims to prevent disasters and reduce damages. Based on the observation data from the surface meteorological station and that from the historical disasters of the 7 counties and 2 districts in the southwest of Shandong in 1971-2010, the time and space distribution characteristics of the main meteorological disasters in the southwest of Shandong are analyzed, such as rainstorm, thunderbolt, gale and hail. This study provides the technology and theory supports for the prevention of meteorological disasters in the southwest of Shandong. The results show that the number of the rainstorm days increases with the increase of the year and increases from the north to the south. The number of thunderbolt days decreases with the increase of the year and decreases from Mudan district to the other countries. Meanwhile, the number of the hail days shows a decline trend and that of the gale shows a much obvious decline trend.
