摘　　要：基于日本气象厅22001号浮标站与美国国家浮标数据中心提供的41008号浮标站观测资料,利用Smith88、YT96、TY01和O02这4种海面粗糙度方案研究中高风速条件下真实海浪效应对海面粗糙度的影响;同时,利用浮标数据和COARE3.0算法,比较中高风速条件下缺乏真实海浪信息时,自主设计的有效波高、谱峰周期参数化方案与COARE3.0自带的Taylor01波浪特征量参数化方案计算海面粗糙度的效果。结果表明,无论哪种浮标资料,不考虑真实海浪效应的2种方案(Smith88和YT96)均比考虑真实海浪效应的2种方案(O02和TY01)计算出的粗糙度偏低,说明在中高风速条件下必须要考虑真实海浪效应对海面粗糙度的影响。此外,初步证实了自主设计的波浪特征量参数化方案在缺乏真实海浪信息时,计算效果优于COARE 3.0算法自带的Taylor01波浪特征量参数化方案。Based on the observation data of 22001 and 41008 buoy station provided by Japan Meteorological Agency and US National Data Center（ NDBC）,surface roughness schemes（ Smith88,YT96,TY01 and O02） were used to research the effects of wave on sea surface roughness for moderate to high wind speed. At the same time,when lacking real waves information under moderate to high wind speed conditions,the self-designed significant wave height,dominant wave period parameterization scheme and Taylor01 wave characteristics parameterization scheme in COARE 3. 0 were used to calculate the effects of sea surface roughness by using buoy data and the COARE 3. 0 algorithm. Results showed that the sea surface roughness calculated by two schemes without considering the waves（ Smith88,YT96） were lower than that calculated by two schemes considering the waves（ O02,TY01）,indicating that we must consider the effect of the waves on the sea surface roughness under the moderate to high wind speeds. In addition,we preliminary confirmed that our scheme was better than Taylor01 scheme when lacking the waves.
