摘要

摘要利用QuikSCAT、ERA5、WAVERYS、drifters和HYCOM + NCODA再分析资料，在热带气旋(tc)和温带气旋(ECs)的背景下对北太平洋地区的资料进行了分析。EC (TC)具有稳定(不稳定)的风向和较宽(较窄)的风向，从而产生较大(较小)的有效波高(H)。对于中、弱风速(W≤26 m s−1)，由于海洋混合层厚度()不够大，低纬度地区的风速(U)大于中纬度地区。对于强风速(W >26 m s−1)，在低纬度地区加深较多，导致U值降低。

Wave and current in extratropical versus tropical cyclones

Abstract Data from QuikSCAT, ERA5, WAVERYS, drifters, and HYCOM + NCODA Reanalysis in the northern Pacific are analyzed under tropical cyclones (TCs) and extratropical cyclones (ECs). The EC (TC) has the stable (unstable) wind directions and wider (narrower) fetch resulting in a larger (smaller) significant wave height ( H s ). For modest and weak wind speeds ( W ≤ 26 m s −1 ), the current speed ( U ) is higher in low latitudes than in mid-latitudes since the oceanic mixed-layer thickness (ℎ) is not large enough. For strong wind speed ( W > 26 m s −1 ), ℎ deepens more in low latitudes and causes lower U .

期刊介绍： The Journal of Oceanography is the official journal of the Oceanographic Society of Japan and open to all oceanographers in the world. The main aim of the journal is to promote understandings of ocean systems from various aspects including physical, chemical, biological, geological oceanography as well as paleoceanography, etc. The journal welcomes research focusing on the western North Pacific and Asian coastal waters, but the study region is not limited to the Asian Pacific. The journal publishes original articles, short contributions, reviews, and correspondence in oceanography and related fields.
