title = "Observations of wind stress direction during Typhoon Chaba (2010)",
abstract = "Direct flux measurements of stress direction taken at the ocean surface during Typhoon Chaba (2010) over 3 days are examined for wind speeds between 12 and 26.5 m s-1. Results show stress deviated up to 35° from the wind direction and resided predominantly between the wind and peak wave directions in both bimodal and unimodal seas. Off-wind stress angle was most pronounced in Chaba's wake where wind sea and swell created an apparent unimodal system with narrow directional spread. These conditions lasted 2 days during which the stress direction was midway between the wind and wave directions. The implications for tropical cyclone forecasting are discussed. Key Points Observations show wind stress direction in typhoon impacted by wavefield Stress direction in typhoon is misaligned up to 35° from the wind direction Wind sea and swell behind typhoon lack separation in frequency and direction.",

note = "Funding Information: ITOP data are freely available from EOL data archives at data.eol.ucar.edu. ITOP was funded by ONR under grant N0014- 09-1-0392. We thank this agency for their support. We acknowledge additional support from NSF (OCE-0526442) for the development of the EASI buoy and ONR (DURIP N00014-09-0818) for funding construction of the second EASI buoy. We are also grateful for contributions of Mike Rebozo, Rafael Ramos, and Neil Williams at RSMAS, the WHOI mooring group led by John Kemp, and for the support and assistance provided by the captains and crew of the R/V Roger Revelle. We thank an anonymous reviewer for questioning our assumption of equal stress directions at differentmeasurement heights and our interpretation of the wavefield. This research was conducted in part thanks to Henry Potter?s NRC research associateship at the Naval Research Laboratory, Washington DC, and Clarence O. Collins? ASEE postdoctoral fellowship at the Naval Research Laboratory, Stennis Space Center.",
