Effects of Bubbles and Sea Spray on Air–Sea Exchange in Hurricane Conditions
The lower limit on the drag coefficient under hurricane force winds is determined by the break-up of the air–sea interface due to Kelvin–Helmholtz instability and formation of the two-phase transition layer consisting of sea spray and air bubbles. As a consequence, a regime of marginal stability develops. In this regime, the air–sea drag coefficient is determined by the turbulence characteristi...
متن کاملThe air-sea interface and surface stress under tropical cyclones
Tropical cyclone track prediction is steadily improving, while storm intensity prediction has seen little progress in the last quarter century. Important physics are not yet well understood and implemented in tropical cyclone forecast models. Missing and unresolved physics, especially at the air-sea interface, are among the factors limiting storm predictions. In a laboratory experiment and coor...
متن کاملParameterization of Air-Sea Fluxes for High Wind Conditions
The standard model for dealing with turbulence and air-sea interactions has three components: (1) The ocean surface can be characterized by its temperature and aerodynamic roughness. (2) Given (1) we can use the wind speed and air temperature/humidity to determine the air sea fluxes. All relevant properties of the profiles of the mean and turbulent fields in the surface layer can them be comput...
متن کاملQuantifying hurricane destructive power, wind speed, and air-sea material exchange with natural undersea sound
[1] Passive ocean acoustic measurements may provide a safe and inexpensive means of accurately quantifying the destructive power of a hurricane. This is demonstrated by correlating the underwater sound intensity of Hurricane Gert with meteorological data acquired by aircraft transects and satellite surveillance. The intensity of low frequency underwater sound measured directly below the hurrica...
متن کاملAir–Sea Enthalpy and Momentum Exchange at Major Hurricane Wind Speeds Observed during CBLAST
Quantifying air–sea exchanges of enthalpy and momentum is important for understanding and skillfully predicting tropical cyclone intensity, but the magnitude of the corresponding wind speed–dependent bulk exchange coefficients is largely unknown at major hurricane wind speeds greater than 50 m s. Since direct turbulent flux measurements in these conditions are extremely difficult, the momentum ...
