Abstract
Different micro-topography will have different effects on wind flow, which makes the characteristics of hilly terrain wind field and its structural wind-induced effect more complicated. This paper presented the characteristics of wind field near various special microtopography in an eastern coastal area with numerical simulation. It was demonstrated that Micro-topography has a great influence on wind field: there will be a phenomenon near the top of the mountain that wind speed increases locally and then flows back, which will be weakened by the shielding effect of the mountain in front; There will be obvious wind acceleration effect in the windward pass, on the contrary, there will be wind deceleration effect in the downwind pass; The variation law of wind speed and wind speed ratio along the slope track is similar to the Slope gradient, when the gradient changes, the wind speed will fluctuate.
