摘要

对星载微波有源和无源仪器(ASCAT和QuikSCAT散射计和WindSat极化辐射计)在地中海和黑海反演的海洋风矢量(OWV)场进行统计比较。比较的时期各不相同:QuikSCAT和WindSat从2003年到2009年，ASCAT和WindSat从2009年到2010年。执行并显示了OWV比较的全局和局部统计数据。一些参数的变化趋势得到了证明，并且在OWV的统计描述中发现了一个普遍的一致性。进行这项研究的原因是需要增加地中海可用观测的数量，以便更好地描述中尺度β (20-200 km，[1])大气过程以及风流与地形相互作用的特征。

Comparison of WindSat and ASCAT wind fields on the mediterranean sea

The ocean wind vector (OWV) fields retrieved on the Mediterranean and Black seas by satellite-borne microwave active and passive instruments (the ASCAT and QuikSCAT scatterometers and the WindSat polarimetric radiometers) are statistically compared each other. The periods of the comparison vary: from 2003 to 2009 for QuikSCAT and WindSat, and 2009 to 2010 for ASCAT and WindSat. Global and local statistics of the OWV comparisons are performed and shown. Trends are evidenced for some parameters, and a general agreement in the statistical description of the OWV is found. The reason for the study was the need to increase the number of available observations in the Mediterranean Sea to better describe meso-scale β (20-200 km, [1]) atmospheric processes and the characteristics of the interaction of the wind flow with the orography.
