论文摘要
在最近的一篇论文中，卢梭·里兹（Rousseau-Rizzi）和伊曼纽尔（Emanuel，2019）提出了表面最大飓风速度的上限。该推导是基于对最大风速点的无限狭窄（差分）卡诺循环的考虑。在这里，我们表明该推导忽略了一个重要的术语，描述了流出中的动能变化。此外，我们强调了适当考虑升级液体水所需的功率的重要性。最后，我们为热和动量表面通量的公式提供了修订，表明如果我们接受Rousseau-Rizzi和Emanuel（2019）所采用的假设，则所得的速度估计并不取决于明智的热量的通量。
In a recent paper Rousseau-Rizzi and Emanuel (2019) presented a derivation of an upper limit on maximum hurricane velocity at the surface. This derivation was based on a consideration of an infinitely narrow (differential) Carnot cycle with the warmer isotherm at the point of the maximum wind velocity. Here we show that this derivation neglected a significant term describing the kinetic energy change in the outflow. Additionally, we highlight the importance of a proper accounting for the power needed to lift liquid water. Finally, we provide a revision to the formula for surface fluxes of heat and momentum showing that, if we accept the assumptions adopted by Rousseau-Rizzi and Emanuel (2019), the resulting velocity estimate does not depend on the flux of sensible heat.
