Momentum Measurement

Scientists at the Naval Research Laboratory-Stennis Space Center (NRL-SSC, Washington, DC) have directly derived the air-sea momentum exchange at the ocean interface using observed ocean currents under Hurricane Ivan and determined that it decreases when winds exceed 32 meters per second. Proper evaluation and measurement of the air-sea exchange under extreme winds is of great importance for modeling and forecasting used in hurricane studies, such as in forecasting of storm track and intensity, surges, waves, and currents.

Since coastal regions have become heavily populated, the results should be of widespread interest to the public, oceanographers, atmospheric scientists, numerical modelers, oil and gas concerns, commerce, and government agencies.
