摘要:Abstract: Based on the observation data from 9 meteorological stations in south-west of Shandong province from 1961 to 2013, the temporal and spatial distribution characteristics of thunderstorm days were analyzed. The results showed that the number of annual mean thunderstorm days was between 20.8 and 24.8 d in south-west of Shandong province from 1961 to 2014, and it decreased from Heze city to northwest and southeast. Thunderstorm weather usually starts in the middle of April, and ends in the early late September. It delayed gradually from south to north in the start and the end time of Thunderstorm weather. Average thunderstorm days were significantly decreasing over time (−2.5 d/10a). Cumulative average thunderstorm days were 1210.3 d, up to 78.1% in summer. Monthly average thunderstorm and precipitation and temperature are in the phase of unimodal type, showing the same relevance among thunder, rain, and heat. The number of annual mean thunderstorm days between the start and end ranged from 145.2 to 157.3 d in south-west of Shandong province. The starting time of the thunderstorm is in advance with time, opposite to the end time, and the interval number does not increase significantly over time. Thunderstorm days’ reduction changed suddenly in 1979, which was above the average before 1979, while below the average after.
