摘要
According to an analysis on the characteristic of 1 Hz wind speed data continuously sampled in the region below 2 m, an empirical model of natural wind was proposed to predict streamwise fluctuating wind gusts in a field based on friction velocity, mean wind velocity and standard deviation at 2 m. The predicted results achieved a good agreement with the experimental data, and the prediction model has a potential value in simulating sand transport under natural wind conditions.
