“…If the w h term is omitted from the top boundary condition of the slab model, as in Shapiro (1983), Thompson and Cardone (1996) and Vickery, et al (2000Vickery, et al ( , 2009, then the azimuthal flow is slightly weaker, the inflow slightly stronger, and w h slightly increased compared with the simulation in Figure 3(a) (not shown).…”

“…Some experimentation revealed that the oscillations can often be triggered by increasing h, in agreement with these authors. However, it is perhaps preferable to think in terms of reducing the ratio C D /h, given the use of a reduced C D by Vickery, et al (2000) to improve the fit of their slab model to observations and that most of the effect of varying h arises through this ratio. A complementary analysis of the oscillations to that of is now presented, which will later be used to help in understanding the moving storm case.…”

“…Powell, et al (2005) truncate at wavenumber one. Vickery, et al (2000Vickery, et al ( , 2009) utilized a grid-point model, but applied more diffusive numerics (including first-order upwinding) than here and post-processed their simulations with a low-azimuthal-wavenumber Fourier decomposition, which would eliminate the feature.…”

“…They may also serve as a component of simplified models of the whole tropical cyclone, most notably as part of the potential intensity theory of Emanuel (1986Emanuel ( , 1988Emanuel ( , 1995. Another important application for slab models is in wind engineering and climate risk assessments, as for example in Vickery, et al (2000Vickery, et al ( , 2009 and references therein. It is important that the limitations and properties of slab models are well understood, precisely because of their potential usefulness in such applications.…”

Diagnostic models of the tropical cyclone boundary layer have important practical uses, including engineering design and climatological risk-assessment studies and as components of tropical cyclone potential-intensity models. A widely used class of such models has been slab models, in which the governing equations are depthaveraged. Here, a slab model is compared with one that fully resolves height, and it is shown that the vertical averaging leads to substantial differences in the simulations. The slab model produces excessively strong inflow and too great a departure of the boundary-layer mean winds from gradient balance. In moving storms, the slab models produce much too strong a motion-induced asymmetry, and can support an asymmetric analogue of the quasi-inertial oscillation previously noted in axisymmetric slab models. Given the considerable impact of the vertical averaging in slab models on the simulated flow in the tropical cyclone boundary layer, it is difficult to recommend their further use for applications where quantitative accuracy is important. Other applications will require care to ensure that the results are not unduly affected by the depth averaging. Part II of this article presents a detailed analysis of the reasons for the differences between depth-averaged and height-resolving simulations of the tropical cyclone boundary layer.

This study presents a novel approach to estimating the intensity of hurricanes using temperature profiles from Global Positioning System radio occultation (GPSRO) measurements. Previous research has shown that the temperature difference between the ocean surface and the eyewall outflow region defines hurricanes' thermodynamic efficiency, which is directly proportional to the storm's intensity. Outflow temperatures in the eyewall region of 27 hurricanes in 2004-2011 were obtained from GPSRO observations. These observations, along with ocean surface temperatures from NASA Modern Era-Retrospective Analysis for Research and Applications, made it possible to estimate hurricane intensities using a simplified hurricane model. Our preliminary results are quantitatively consistent with best-track values from the National Hurricane Center within 9.4%. As a by-product of our study, we present for the first time GPSRO vertical temperature profiles in the vicinity of the eyewall region of hurricanes, which we compared with collocated temperature profiles from the European Centre for Medium-Range Weather Forecasts Reanalysis Interim (ERA-Interim). Some of the GPSRO data sets reveal a double tropopause in the vicinity of the eyewall-a characteristic that we do not see in ERA-Interim. We conclude that GPSRO observations can be of supplementary assistance in augmenting existing data sets used in hurricane intensity estimation. GPSROs' cloud-penetrating capability and high vertical resolution can be useful in providing soundings in the area close to the eyewall region of hurricanes revealing detailed information about their thermal structure, potentially advancing our current knowledge of their dynamics, evolution, and physics.
