< p >风在他们眼墙,最大速度Vmax瘦环立即眼周。随着距离风脱落。如果一个飓风兰金涡旋,风速度半径R从眼睛的中心将V (R) = Vmax X(急性脑病/ R),其中急性脑病是半径。在现实中摩擦通常可以防止飓风被一个完美的兰金涡旋。Instead it typically a modified Rankine vortex, with V(R) = Vmax X (Reye/R)^n, where n is typically in the range 1/2 < n < 3/4 (perhaps n = 2/3 is the best overall average value). Of course this is a radially-smoothed-out wind velocity distribution. In the approach of an actual hurricane, wind does not increase monotonically as R decreases. But V(R) = Vmax X (Reye/R)^2/3 typically approximates the secular trend of its increase.
