Tóm tắt

Dữ liệu từ phao Argo được thu thập từ năm 2002 đến 2011 đã được phân tích để kiểm tra ảnh hưởng của biến động hệ thống dòng Kuroshio Extension (KE) đến quá trình hình thành Nước Chế Độ Trung Tâm. Ngay phía bắc phần đầu nguồn của dòng KE tại 140–152°E, việc hình thành một loại Nước Chế Độ Trung Tâm nhẹ hơn vào mùa đông đã diễn ra tích cực trong thời kỳ không ổn định của đầu nguồn dòng KE từ 2006–2009 và đã giảm khi đầu nguồn dòng KE nằm trong thời kỳ ổn định từ 2002–2005 và 2010–2011. Sự biến đổi hình thành thập kỷ này trái ngược với sự biến đổi của Nước Chế Độ Cận Nhiệt Đới ngay phía nam dòng KE.
