Atmosphere Work Unit

The Atmosphere work unit develops robust atmospheric models to simulate hurricane and extratropical wind and pressure fields to drive the MORPHOS wave and circulation models.

Hurricane Ivan Windfield Reconstruction

[an error occurred while processing this directive]
The accuracy of modeled waves, surges, and morphologic response is critically dependent on the accuracy of the wind and pressure fields used to force the coastal processes models. The development of a robust storm atmospheric forcing system is an important research and development element of MORPHOS with a focus on improvements to the wind and pressure field estimation for extratropical storms and hurricanes. Specific research topics include updates to the Tropical Cyclone-96 (TC96) methodology, revised drag coefficient, impact of atmospheric boundary layer height variations on hurricane strength and land falling effects, and development and testing of alternatives in the construction of historical hurricane wind and pressure fields for recent, highly documented hurricane systems.
