Drag coefficient reduction at very high wind speeds
[1] The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other intense marine meteorological phenomena. We present a unified boundary layer model for (K10), which takes account of both the wave field and spray production, and asympt...
متن کاملImpact of Breaking Wave Form Drag on Near-Surface Turbulence and Drag Coefficient over Young Seas at High Winds
The effects of breaking waves on near-surface wind turbulence and drag coefficient are investigated using large-eddy simulation. The impact of intermittent and transient wave breaking events (over a range of scales) is modeled as localized form drag, which generates airflow separation bubbles downstream. The simulations are performed for very young sea conditions under high winds, comparable to...
متن کاملUsing Wind Setdown and Storm Surge on Lake Erie to Calibrate the Air-Sea Drag Coefficient
The air-sea drag coefficient controls the transfer of momentum from wind to water. In modeling storm surge, this coefficient is a crucial parameter for estimating the surge height. This study uses two strong wind events on Lake Erie to calibrate the drag coefficient using the Coupled Ocean Atmosphere Wave Sediment Transport (COAWST) modeling system and the the Regional Ocean Modeling System (RO...
متن کاملNOTES AND CORRESPONDENCE Impact of the Reduced Drag Coefficient on Ocean Wave Modeling under Hurricane Conditions
Effects of new drag coefficient (Cd) parameterizations on WAVEWATCH III (WW3) model surface wave simulations are investigated. The new parameterizations are based on a coupled wind–wave model (CWW) and a wave tank experiment, and yields reduced Cd at high wind speeds. Numerical experiments for uniform winds and Hurricane Katrina (2005) indicate that the original Cd parameterization used in WW3 ...
متن کاملOrographic wave drag modelling
The main topic of this article is wave propagation in disordered media. Of particular interest is the long wave regime where an arbitrary rapidly varying orography is modelled as a (stochastic) disordered medium. A brief description of mathematical theory and results is presented. The apparent diffusive behaviour, predicted in the theory for the wave-orography interaction, is confirmed through ...
