Variations of the North and South Pacific Subtropical Gyres over the Past 400 kyrs

Abstract

The gyre in the ocean is thought to play an important role in the climate system as and material low and high latitudes. In late the large variation of intensity of North Pacific Subtropical Gyre associated with glacial-interglacial cycles with 23 kyr cycle suggesting a precession control on intensity of NPSG circulation. the driving the long-term variability gyre and eastern gyres. west-east Δ SST record in SPSG show orbital scale variations over the past 400 kyrs.
