Characterization of the wind field in the Kuroshio extended body sea based on buoy observation

Abstract

In this paper, we propose to combine the data from CKEO and KEO buoys and reanalysis data to study the prevailing wind types, temperature changes and carbon fluxes in the Kuroshio Extension in different seasons in recent years, in order to deepen our understanding of the physical and chemical environment and its evolution in the sea. In this paper, we analyze the characteristics of the wind field of the Kuroshio Extension using the CKEO buoy system at a fixed coordinate (149.25°E, 39°N) in the northwest Pacific Ocean, using four methods: wind speed and direction rose diagram, wind speed comparison line diagram, temperature comparison line diagram and carbon flux variation line diagram. Compared with the KEO buoy observation system, the CKEO buoy observation system provides high quality sea-air observation data in the Kuroshio Extension, which provides valuable information for the study of sea-air interaction in the Kuroshio Extension.
