| 利用中國近海23個(gè)浮標(biāo)對2015年一整年的ASCAT軌道風(fēng)場和ERA-Interim再分析風(fēng)場進(jìn)行質(zhì)量評估,并對比了ERA-Interim和CFSV2兩種再分析風(fēng)場資料在中國近海的適用性。結(jié)果表明:ASCAT在中國近海與浮標(biāo)風(fēng)速的一致性優(yōu)于ERA-Interim,而二者與浮標(biāo)風(fēng)向的一致性則相差不大。同時(shí),對比CFSV2與ERA-Interim的誤差統(tǒng)計(jì)結(jié)果發(fā)現(xiàn),CFSV2的風(fēng)速誤差較ERA-Interim略小,風(fēng)向誤差相差不大。 |
| In this paper, we evaluate the quality of ASCAT orbital and ERA-Interim reanalysis wind field in 2015 using 23 buoys deployed in China offshore seas, and also compare the suitability of ERA-Interim and CFSV2 reanalysis wind field data for China offshore sea. Compared with buoy observations, it is found that the wind speed of ASCAT is more consistent than that of ERA-Interim reanalysis, whereas the consistency of the two datasets shows no significant difference regarding wind direction. Comparing the error statistics of CFSV2 and ERA-Interim reanalysis, we also demonstrate that the wind speed error of CFSV2 is slightly smaller than that of ERA-Interim reanalysis, and the wind direction error is largely the same. |
