The paper aims to identify wind characteristics at the Thien Nga - Hai Au field area using high resolution data generated by the WRF-ARW model. The results indicate that Northeast and Southwest winds are the most frequent, as compared to other directions. The highest wind speed values are observed during the winter monsoon. These findings exhibit reasonable consistency with those of climate survey in the Southern Bien Dong Sea. In addition, the study calculates the return period for extreme wind values, comparing between the cases of monsoon activity and storm activity. The extreme wind speed values are higher in winter (32.0 - 34.0 m/s) compared to summer (29.0 - 30.0 m/s), corresponding to return periods of 50 - 100 years. It is found that highest extreme wind speeds are associated with storm events (40.0 - 46.0 m/s).
