Observations of wind stress direction during Typhoon Chaba (2010) Academic Article uri icon


  • AbstractDirect flux measurements of stress direction taken at the ocean surface during Typhoon Chaba (2010) over 3days are examined for wind speeds between 12 and 26.5ms1. 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. Offwind 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 2days during which the stress direction was midway between the wind and wave directions. The implications for tropical cyclone forecasting are discussed.
