Abstract:Based on annual maximum wind speed data from 121 meteorological stations in Shandong from 1981 to 2016, the spatial characteristics, the temporal evolution, mutation, and recurrence intervals of annual maximum wind speed are analyzed using climate tendency rate and MannKendall mutation test, meanwhile the characteristics of other wind parameters such as gust wind speed and wind days are analyzed. The results show that the annual average maximum wind speed presents a significant downtrend with fluctuations year by year and the climate tendency rate is -141 m·s-1·(10 a)-1. The maximum wind speed in coastal areas and central mountainous areas is larger than that in the south and southwest of Shandong. The maximum wind speed since 2000 has an obvious decrease compared to that in 1980s and 1990s. The most obvious decrease happens in Laizhou Bay and southeastern coastal areas of Shandong Penisula, while the decrease is smaller in areas like the southeast of Shandong. The maximum wind speed has abrupt change in 2002 and its is obviously smaller after the abrupt change. The abrupt change of maximum wind speed happens in different time for different areas. The spatial distribution of maximum wind speed of the recurrence interval of 50 years and 100 years is similar to that from the observation data.
