The Coupled Boundary Layers Air-Sea Transfer CBLAST Departmental Research Initiative and the U. S. Weather Research Program USWRP Hurricane at Landfall Initiative identify hurricanes as the least understood yet most important high-wind event. A paucity of measurements in the atmospheric boundary layer, both in research and operations, is recognized as an important source of uncertainty in hurricane forecast models. Such measurements have been very difficult to obtain since the most turbulence sensors function poorly or not at all in winds and rain above 20 m s-1. Filling this knowledge gap is crucial to improving predictions of hurricane track, size and intensity, and to understanding air-sea exchange under high winds. The Extreme Turbulence ET probe is being developed to acquire turbulent flux data in the atmospheric surface layer in hurricane-force winds.
