New Analysis of Flux Data Toward Simpler Algorithms for Air-Sea Surface Fluxes
Abstract
Funds are provided to conduct research to on the following objectives: 1) Build an archive of air-sea flux data obtained data from offshore towers, ships, and particularly FLIP. The PI will reprocess data from the ASIT site on Martha~s Vineyard that were collected during OHATS and the CBLAST weak-wind projects, and obtain CTV turbulence data measured roughly 10 m above the sea surface during CASPER. 2) Evaluate more rigorously the apparent weak, or undetectable, dependence of the transfer coefficients on the stratification and investigate the physics behind this independence. 3) Develop flux algorithms for the weak-wind regime. Weak wind is an obvious marine regime in which Monin-Obukhov similarity theory is fundamentally flawed and, thus, has incurred many patches that attempt to make it agree better with the data. The PI will attempt to better represent a generalized velocity scale withoutsignificant increase of complexity. 4) The PI will test new parameterizations in large-scale models like NAVGEM and COAMPS in collaboration with Jim Ridout and Shouping Wang at NRL-Monterey.
