The wind speeds near ground influenced by typhoon "Neoguri" are obtained at the field measurement site of Tongji university around Pudong International Airport, and the variation regularity of fluctuating wind speeds near ground with mean wind speed at the lattice tower structure is studied under the influence of typhoon "Neoguri" . At the same time,it can be obtained that the probability density function of fluctualting wind speed near ground is in good agreement with Gaussian distribution curve under the impact of typhoon.
