Multichannel Singular Spectrum Analysis of the Oceanic Angular Momentum

Student: Elena Shcheplova

Supervisor: Leonid Zotov

Faculty: HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE)

Educational Programme: Mathematical Methods of Natural Sciences and Computer Technologies (Master)

Final Grade: 8

Year of Graduation: 2016

The object of a research is oceanic angular momentum (OAM) in 1993 - 2010, derived from the date of ЕССО KF080 model. The aim of the work is inquiring into changes in   oceanic angular momentum within its affect on the Earth rotation. The data is refined and the main components are grouped and determined by means of multi-channel spectrum analysis. Based on aforementioned results, one has drawn annual, middle-and long-term variability which vividly demonstrate fields of the most significant changes. A complex of programs, within on Python and MatLab, implementing MCCA method and map-drawing has been developed as a result of the research. Thus, it was revealed that a correlation between oceanic angular momentum and climate changes exists.
