摘    要:本文先对NCEP分析风、QSCAT/NCEP混合风、MM5中尺度模式分析风场进行了比对分析,发现具有高分辨率的QSCAT/NCEP混合风资料给出的高风速数值较好,但给出的高风速开始时间相对较早;NCEP分析风资料给出的高风速数值明显偏小;MM5分析风场较为可信,只不过模拟的高风速数值还是相对偏小.使用COARE算法(版本3.0)计算了四种资料情况下的渤、黄海海域一次冷空气大风过程的海表面湍流热通量,并与MM5诊断分析结果进行了对比分析.结果发现相同资料情况下,MM5结果跟COARE算法所算海气热通量(包括感热和潜热)在区域分布和时间变化规律上均较为一致,中、低风速情况下,结果比较接近;但是高风速情况下两者差异显著.

关 键 词:COARE算法  MM5  感热通量  潜热通量  海-气界面

Abstract:The different wind data including the NCEP analysis winds,QSCAT/NCEP blended winds,MM5 analysis winds are firstly compared in this paper.It is found that the blended winds with high resolution can give a good high wind value,but the start time of the strong winds is relatively earlier.The high values of the strong winds from NCEP are apparently smaller.The MM5 analysis winds are well agree with the observed results except during strong wind speeds.The wind data with other different marine data of air temperature and humidity are used for computing the heat fluxes at the air-sea interface by using the COARE algorithm(Version:3.0)for a synoptic case in the sea area of the Bohai sea and Yellow sea.The results are used for verifying the flux output from the MM5 model operationally running in National Marine Environmental Forcasting Center.The comparative analyses show the output of the air-sea fluxes from MM5 is well agree with the COARE fluxes under the middle and the low winds,but much different under the strong winds.
Keywords:COARE algorithm  MM5  sensible heat flux  latent heat flux  air-sea interface
