Air-Sea Enthalpy and Momentum Exchange at Major Hurricane Wind Speeds Observed during CBLAST (2012, positive): “Powell et al. (2003) provided the first indications of a slight decrease in CD from maximum values around 2.5 3 10 23 at 30–40 m s21.”

The role of the oceans in climate (2003, background): “Recent evidence suggests that there may be an upper limit to the exchange coefficient at hurricane-force wind speeds, as the sea surface becomes covered with a layer of foam (Powell et al., 2003).”
Effect of Surface Waves on Air–Sea Momentum Exchange. Part II: Behavior of Drag Coefficient under Tropical Cyclones (2004, methodology): “Symbols represent Cd estimated from GPS sonde data in various hurricanes (Powell et al. 2003).”
Structure of the airflow above surface waves (2016, background): “The development of extreme weather events (such as hurricanes) is dependent on the drag at the ocean surface (Powell et al., 2003; Donelan et al., 2004; Bell et al., 2012).”
The Maximum Intensity of Tropical Cyclones in Axisymmetric Numerical Model Simulations (2009, background): “Because CD seems to be a more uncertain parameter (e.g., Powell et al. 2003; French et al. 2007), we vary this parameter across a broad range of values.”
On the exchange of momentum over the open ocean (2013, positive): “While this value is much larger than those inferred from aircraft observations in hurri-canes (Black et al. 2007), the value of 10 3 3 C D 10 N ’ 2.8 at 30ms 2 1 falls well within the observations and suggested parameterizations reported by Powell et al. (2003).”
Dynamics of Winds and Currents Coupled to Surface Waves (2010, result): “Recent results collected in hurricanes verify the laboratory trends but find lower saturated values with a possible decrease at large Ua (Powell et al. 2003).”
Wave Modeling—Missing the Peaks (2009, background): “Powell et al. (2003) have clearly shown that in this range the production of foam due to breaking, also directly induced by wind, is such that the foam completely fills the troughs between the sequential waves.”
A Note on the Drag of the Sea Surface at Hurricane Winds (2005, methodology): “Analysis of the measured wind profiles at hurricane wind speeds (Powell et al., 2003) reveals that, in the atmospheric layer 10–200 m above the ocean, the wind speed u is described by the logarithmic profile E-mail: makin@knmi.nl uðzÞ ¼ u j ln z z0 ; ð2Þ where j is the von Karman constant and z0 is…”
