Abstract

Field observations that provide some further support for the effects of swell on the 10 m air-sea drag coefficient were presented. The investigation was preliminary and focused on cases where the drag coefficient dropped to very low levels at moderate wind speeds. Data from 36 separate flights of the NOAA LongEZ covering a variety of wind and wave conditions were used for the investigation. The results showed that the drag depression was consistent with swell modes travelling in a following wind direction.
