In HEXOS, a programme of coordinated laboratory, field and model studi
es, an international group of participants has extended the range of m
easurements of evaporation from the sea and has investigated the role
of droplets in the transfer of water to the atmosphere. Predictions of
a rapid rise in the evaporation coefficient at wind speeds above 15 m
s(-1) have not been substantiated. Wind stress measurements showed a
relationship with wave age. New methods were developed for coping with
flow distortion.
