摘要 通过与浮标观测资料的对比分析,指出NCEP动量通量、再计算NCEP热通量更能够代表NCEP再分析数据库的数值模拟效果。当风速大于20m/s时,数值模拟的湍通量低于浮标块体湍通量,当风速在10～20m/s时,数值模拟的湍通量高于浮标块体湍通量。同时还发现数值模拟结果的延迟现象,以及不能反映大风过后快速的海气温差变化而引起的感热通量变化。 The comparisons and analysis of turbulent flux between NCEP reanalysis data and buoy data show that NCEP momentum flux and recalculated NCEP heat flux can represent the effect of numerical simulation of NCEP reanalysis database better. When wind speed exceeds 20m/s, the turbulent flux of numical simulation is smaller than buoy bulk turbulent flux. When wind speeds occur from 10m/s to 20m/s, the turbulent flux of numical simulation is larger than buoy bulk turbulent flux. Meantime, the delay phenomena of nuluical simulation result is found, and the change of sensitive heat flux caused by the quickly change of air sea temperature difference after large wind can not be expressed well.
