The long-term goal of this project is to understand the |
|
effects of surface waves on the structure of the marine |
|
atmospheric surface layer and surface flux |
|
parameterizations under a broad range of wind-wave |
|
conditions. The project is part of the High Resolution |
|
Wave-Air-Sea Interaction research initiative (HiRes). The |
|
objectives of the project are to characterize low-level |
|
atmospheric wind and thermodynamic profiles and |
|
variations, to understand oceanic and atmospheric large- |
|
scale forcing that affects boundary layer properties, and |
|
to understand the role of measured wave field in |
|
modifying atmospheric surface fluxes. Our work within |
|
this project consists of three parts: measurements, the |
|
subsequent data analyses, and mesoscale model |
|
evaluation/improvements. The ship-based measurement |
|
efforts include high-rate sampling of the turbulent field |
|
for direct covariance flux measurements; continuous |
|
sampling of low-level wind profiles by the ship-based |
|
acoustic Sodar; rawinsonde measurements of the |
|
troposphere; and a suite of mean variables for |
|
quantifying the low-level thermodynamic and dynamic |
|
fields, downward radiation, and sea surface temperature |
|
measurements. The data analyses will focus on the low- |
|
level surface layer properties and surface flux |
|
parameterization involving sea state parameters. In |
|
addition to evaluating current COAMPS, we will experiment |
|
with sea-state dependant surface flux parameterization in |
|
COAMPS, possibly in coupled mode. |
