飓风模拟的一个关键组成部分是在给定风暴强度、大小和平移速度的情况下，飓风风场的良好表示。在这里描述的调查中，飓风运动方程的完全非线性解被求解，然后参数化用于快速运行的模拟。这里描述的飓风模型考虑到了海面粗糙度变化和海气温差对估计的表面风速的影响。模型和观测到的飓风风速记录之间的比较进行比较，其中一个比较10分钟的平均风速和峰值阵风风速。由此产生的风场模型代表了最物理基础和验证模型中使用的飓风风速预测概率的估计。
A critical component in the simulation of hurricanes is a good representation of the hurricane wind field when given information of the storm intensity, size, and translation speed. In the investigation described here, the full nonlinear solution to the equations of motion of a hurricane are solved and then parameterized for use in fast-running simulations. The hurricane model described here takes into account the effects of changing sea surface roughness and the air-sea temperature difference on the estimated surface-level wind speeds. Comparisons between modeled and observed hurricane wind speed records are performed where one compares both the 10-min mean wind speeds and the peak gust wind speeds. The resulting wind field model represents the most physically based and validated model used in the estimate of hurricane wind speed exceedance probabilities.
