Analysis on Wind Field Characteristics of the First Hundred Kilometers of Wind Area along Nanjiang Railway
The wind data in wind monitoring point of 2015, 2016 Nanjiang Railway of first 100 km are selected for analysis of wind field characteristics. The results show that the wind level is relatively high and the duration is relatively long in the first 100 km wind area of Nanjiang Railway. The maximum instantaneous wind speed can reach 61.2 m/s, and the wind direction is mostly concentrated between WNW-NNW. The average wind speed, average wind direction, turbulence intensity and gust factor are analyzed by choosing the data of wind monitoring points in typical gale weather, the results show that the weather fluctuation is strong, and the high level of wind duration is long.
