| Abstract: | The windy weather characteristics were analyzed based on meteorological data from 1958 to 2007 at Fuhai county. The results show that the windy weather often appears from 1950s to 1970s, and it obviously decreases since 1980s. The number of annual windy days is about 20 days after 1993. The windy days are most in spring and least in winter. The windy duration is about 0-5 hours. The windy weather that the duration is more than 19 hours usually happens in spring and autumn. The windy weather often appears from May to August, especially in afternoon. There is not obvious difference in other months. The windy weather often occurs in plain areas, followed in middle and lower mountain areas, and is least in desert areas. Westerly wind often happens in spring and summer, and easterly wind is in autumn and winter. The wind speed of westerly wind is greater than that of easterly wind. The maximum wind speed often comes from westerly wind. |
