The results of 10 sets of experiments suggest that in comparison with only one vortex , the intensity of the inward propagation of vorticity strengthens distinctly , vorticity detains in the inner region of typhoon circulation for a longer time , and the local maximum wind speed in the inner region increases clearly 10组试验的结果指出:与单涡条件相比,涡量内传的强度显著加强,涡量滞留在台风内区的时间加长,内区局域最大风速增大的现象更加清楚。
Based on wind speed observation record with drawback , it is proved that the exponent expressing terrain roughness can be calculated according the monthly maximum wind speed records at various height levels . wind characteristics of bridge site are determined by statistical method 针对桥址区风速观测记录的特点,证明了利用不同高度处月最大风速记录推算地表粗糙度影响系数的可行性,并对通过最小二乘拟合得到的地表粗糙度影响系数进行统计分析,最终确定桥址区风特性。
