TLDR
In this paper, the authors used data from five levels (900 to 180 mb) to depict the structure of a mature hurricane and derived estimates of the drag coefficient under hurricane conditions from a different formulation, utilizing the momentum budget in the inflow layer.Abstract:
Aircraft data from five levels (900 to 180 mb.) are used to depict the structure of a mature hurricane. Horizontal analyses, vertical cross sections, and various budgets, which have been prepared from the research flight data only, are presented. New estimates of the drag coefficient under hurricane conditions are derived from a different formulation-utilizing the momentum budget inthe inflow layer.read more

Reduced drag coefficient for high wind speeds in tropical cyclones
TL;DR: It is found that surface momentum flux levels off as the wind speeds increase above hurricane force, contrary to surface flux parameterizations that are currently used in a variety of modelling applications, including hurricane risk assessment and prediction of storm motion, intensity, waves and storm surges.

Air-sea bulk transfer coefficients in diabatic conditions
TL;DR: In this paper, the bulk transfer coefficients of the sea surface have been estimated based on the Owen-Thomson theory on the transfers of heat and mass between a rough surface and the flow above it.

The Maximum Potential Intensity of Tropical Cyclones
TL;DR: In this paper, a thermodynamic approach to estimate the maximum potential intensity (MPI) of tropical cyclones is described and compared with observations and previous studies, which requires an atmospheric temperature sounding, SST, and surface pressure; including the oceanic feedback of increasing moist entropy associated with falling surface pressure over a steady SST.

Wind-stress coefficients over sea surface from breeze to hurricane
TL;DR: The empirical formula proposed recently relating wind-stress coefficient to wind velocity, C10 = (0.8 + 0.065 U10) × 10−3, appears to be applicable even in hurricanes as discussed by the authors.

A study of the filling of hurricane donna (1960) over land
TL;DR: The processes which resulted in the filling of a tropical cyclone over land have been investigated in this paper, where the eddy fluxes of latent and sensible heat and the dissipation of kinetic energy at the earth's surface have been computed for a 3-day period.

Budget of angular momentum and energy in tropical cyclones
E. Palmen,Herbert Riehl +1 more
TL;DR: In this article, the surface stress in tropical storms is computed as a function of the radius, from mean wind data in the troposphere, and the absolute angular momentum budget is carried by the symmetrical part of the circulation near the core, and that the asymmetrical part contributes up to 50 per cent at a distance of 6 deg lat from the center.
