摘　　要：The dimensionless roughness length derived from dimensional analysis bears a relation to wave age, and the dimensionless form of roughness length can be expressed with the relation with a significant wave height. Based on six experiments （HEXMAX, RASEX, BIO steady platform, Lake Ontario data analysis FETCH, CBLAST low wind）, we verified that the Charnock parameter, Zch, and dimensionless roughness length, Z0/Hs, are dependent on wave age, ua/cp. Moreover, we constructed a new scheme for roughness length, and explored its sensitivity to friction velocity and wave age. Combining the newly developed parameterization scheme （PS07） with COARE （Coupled Ocean-Atmosphere Response Experiment V.3.0） algorithm, we calculated the data from the North Sea Platform experiment in December, 1985, and made an attempt to validate the suitability of the PS07 compared to the other three schemes of COARE. We found that the calculated results based on the PS07 are close to the measurements. We also conducted an experiment in which the PS07 was combined with the nested model of waves coupling in datasets of 3 typhoons that occurred at the Zhanjiang Seaport. The comparison results between the calculated and observed waves around the Naozhou Island indicate that the new parameterization scheme （PS07） has a good applicability.更少的粗糙长度从维的分析导出的尺寸有一种关系少些挥动年龄，和尺寸粗糙的形式长度能与重要波浪高度与关系被表示。基于六个实验(HEXMAX， RASEX，简历稳定的站台，安大略湖数据分析取， CBLAST 低风) ，我们证实 Charnock 参数， zch，和尺寸更少粗糙长度， z0/Hs，依赖于波浪年龄， u */cp。而且，我们为粗糙长度构造了一个新计划，并且探索了它的敏感到磨擦速度和波浪年龄。把最新发达的 parameterization 计划(PS07 ) 与 COARE (联合海洋空气反应实验 V.3.0 ) 相结合算法，我们在 1985 年 12 月从北方海平台实验计算了数据，并且尝试了与 COARE 的另外的三个计划相比验证 PS07 的适用性。我们发现计算结果基于 PS07 接近大小。我们也进行了 PS07 与在发生在 Zhanjiang 海港的 3 台风的数据集联合的波浪的嵌套的模型在被相结合的一个实验。在在 Naozhou 岛附近的计算、观察的波浪之间的比较结果显示新 parameterization 计划(PS07 ) 有好适用性。
