Study that uses buoy and tower data to improve how models forecast the interaction between the atmosphere and ocean in tropical cyclones released online in the Journal of Geophysical Research Oceans – Hurricane Research Division

Modeling the interaction between the atmosphere and the ocean is important for accurate forecasting of tropical cyclones, especially their intensities.  Because these interactions are so complex, we typically model these interactions using what we call parameterizations to estimate what is really happening.  One parameter, the drag coefficient, is the resistance between motions in the atmosphere and ocean. This study looked at observations from towers and buoys to study the interaction and improve the parameterizations. It is found that the behavior of the drag coefficient varies within the tropical cyclone and depending on whether the tropical cyclone is over the open ocean or in coastal regions.

The study can be found here. For more information, contact aoml.communications@noaa.gov.
