New study directly quantifies air-sea momentum exchange in hurricane force winds for the first time
In recent years, uncrewed surface vehicles (USV) have become vital tools used to collect observations to improve hurricane forecasts. To fully understand how storms intensify, scientists need data at the air-sea interface where energy is transferred from the ocean to tropical cyclones. This data is most effectively collected by USVs because of their unique ability to operate in dangerous environments and extreme conditions. In a new study, scientists are able to directly quantify the air-sea momentum exchange (termed ‘wind stress’) and related frictional drag effect that acts to slow a hurricane’s rotating winds. These direct measurements of this process are the first to be collected over the ocean in hurricane-force winds.
