Applications of a Sea-Surface Roughness Parameterization Scheme to the Nested Model of Storm Surge, Current and Wave Coupling
Procedia earth and planetary science(2011)
摘要
The sea surface roughness parameterization scheme developed by Pan, Sha et al. (PS07) bears a relation to wave age, and the dimensionless form of roughness length can be expressed with the relation with significant wave height. Based on 4 experiments (HEXMAX, RASEX, BIO steady platform, Lake Ontario Data), we make an attempt to validate the suitability of the PS07 scheme under different wind fetch and sea state. We found that the calculated results based on PS07 are close to that given by the eddy correlation method. We also conducted an experiment in which the PS07 was combined with the nested model of waves coupling in datasets of 4 typhoons occurred at the Zhanjiang Seaport. The comparison results between the calculated and observed Zhanjiang seaport water-level rise and waves around the Naozhou Island indicate that the PS07 scheme has a good applicability.
