Qiu HE, Fenglin TIAN, Xiaokun YANG, et al. Lagrangian eddies in the Northwestern Pacific Ocean[J]. Journal of Oceanology and Limnology, 2022, 40(1): 66-77. DOI: 10.1007/s00343-021-0392-7.
The Lagrangian eddies in the western Pacific Ocean are identified and analysed based on Maps of Sea Level Anomaly (MSLA) data from 1998 to 2018. By calculating the Lagrangian eddy advected by the AVISO velocity field
we analyzed the variations in Lagrangian eddies and the average transport effects on different time scales. By introducing the Niño coefficient
the lag response of the Lagrangian eddy to El Niño is found. These data are helpful to further explore the role of mesoscale eddies in ocean energy transfer. Through normalized chlorophyll data
we observed chlorophyll aggregation and hole effects caused by Lagrangian eddies. These findings demonstrate the important role of Lagrangian eddies in material transport. The transportation volume of the Lagrangian eddy is calculated quantitatively
and several major transport routes have been identified
which helps us to more accurately and objectively estimate the transport capacity of Lagrangian eddies in the western Pacific Ocean.
