The meteorological element is one of important factors that influence the engineering design and programming

especially the wind velocity which affects the towering structure in the atmospheric boundary layer.However

in the current engineering design and meteorological evaluation

the meteorological station’s wind velocity is applied

which are not representative the real wind character in the project spot

thus result in the hidden trouble to the design and constructtion. Aiming at the special need of design and evaluation with the meteorological data for large project

the paper discussed the revision methods for the station wind data and the short-period ones on spot respectively.By means of contrast tests between weather station and project spot wind data for several large engineering projects

the results show that it’s necessary to make corrections to the station data in height above ground

underlying surface effect and time interval.Moreover

the correction index and the gust one for 2 min/10 min time interval data on spot are smaller than the building criterion ones recommended by weather station and affected by the project environment.For several applications

the average ratio of 2 min/10 min of engineering spot is 1.09

while 1.16 for weather station

and average of the unstable gust index which were mostly affected by different physiognomy

underlying surfaces and weather processes reached 1.31

only 87 percent of the ones recommended by weather station.Finally

T-test method was used to verify the homogeneity for long-time station data and the obvious difference data were revised with the mean of ratio.While for the shorttime data on spot

it can be extrapolate to long-period serial with mathematical relationship basing on the synchronization observation in local and station.The revised methods mentioned above have been used in several large highway bridge engineering

which were proved to be practically useful

and also can be used for other similar projects.
