摘要

Abstract

Near-inertial oscillation is an important physical process transferring surface wind energy into deep ocean. We investigated the near-inertial kinetic energy (NIKE) variability using acoustic Doppler current profiler measurements from a mooring array deployed in the tropical western Pacific Ocean along 130°E at 8.5°N

11°N

12.6°N

15°N

and 17.5°N from September 2015 to January 2018. Spatial features

decay timescales

and significant seasonal variability of the observed NIKE were described. At the mooring sites of 17.5°N

15°N

and 12.6°N

the NIKE peaks occurred in boreal autumn and the NIKE troughs were observed in boreal spring. By contrast

the NIKE at 11°N and 8.5°N showed peaks in winter and troughs in summer. Tropical cyclones and strong wind events played an important role in the emergence of high-NIKE events and explained the seasonality and latitudinal characteristics of the observed NIKE.
