Abstract:
Based on the analysis of tropical cyclones in six national basic stations in the recent 60 years, combining with the data of the lightning location system in the recent 4 years, the temporal and spatial distributions of tropical cyclones, coast gales, and ground lightning flashes influencing the coastal region of the northern Jiangsu are analyzed, and their effects on the wind forms in the region are discussed. Results show: (1) Tropical cyclones influencing the coastal region of the northern Jiangsu are mainly moving northwestward on the ocean and northward after landing, and the tropical cyclones of this kind account for 732 (2) Since 1945, 877% of tropical cyclones brought economic benefits for wind power in this region; 123% of tropical cyclones did not cause losses after adequate defenses; and there was no destructive tropical cyclone. (3) The lightning protection examination of wind driven generators should be strengthened in thunderstorm season (June to August), especially in Yancheng. (4) The extreme wind speed and maximum wind speed with a recurrence period of 50 years comply with the national standards for safe operation for Model Ⅲ/Ⅱwind driven generators.
