ERS Wind Scatterometer Data Processing and Observation of Ocean Wind Field Abnormal of El Nino
ERS散射计全球海面风场数据处理与ElNino海面风场异常观测

Spaceborne scatterometertechnologyis meaningfulforobservation ofthe globalocean windfield.The Process ing and analysis method were studiedforthe European Remote Sensing Satellite (ERS) wind scatterometerdata (WNF) . The Global ocean wind fields were averagedin March,June and December 1997 respectively.They were compared with those ofJune 1996 and October 1995 .The wind field abnormal was observed in the equatorial Western Pacific ,which wasrelatedto El Nino 1997 .The evolution characteristicsofocean wind abnormal(speed and direction) relatedto El Ni no 1997 wasanalysed using ERSWNFdata.Itisshownthatspaceborne scatterometer playsanimportantroleinthe mon itoring of gloabalchanges.
