Long-term prediction of El Niño-Southern Oscillation using reservoir computing with data-driven realtime filter
Takuya Jinno, Takahito Mitsui, Kengo Nakai +2
In recent years, the application of machine learning approaches to time-series forecasting of climate dynamical phenomena has become increasingly active. It is known that applying…
Effects of additive noise on the stability of glacial cycles
Takahito Mitsui, Michel Crucifix
It is well acknowledged that the sequence of glacial-interglacial cycles is paced by the astronomical forcing. However, how much is the sequence robust against natural fluctuations…
Challenges for ice age dynamics: a dynamical systems perspective
Michel Crucifix, Guillaume Lenoir, Takahito Mitsui
This chapter is dedicated to the slow dynamics of the climate system, at time scales of one~thousand to one million years. We focus specifically on the phenomenon of ice ages that…
Influence of external forcings on abrupt millennial-scale climate changes: a statistical modelling study
Takahito Mitsui, Michel Crucifix
The last glacial period was punctuated by a series of abrupt climate shifts, the so-called Dansgaard-Oeschger (DO) events. The frequency of DO events varied in time, supposedly bec…
Bifurcations and strange nonchaotic attractors in a phase oscillator model of glacial-interglacial cycles
Takahito Mitsui, Michel Crucifix, Kazuyuki Aihara
Glacial-interglacial cycles are large variations in continental ice mass and greenhouse gases, which have dominated climate variability over the Quaternary. The dominant periodicit…
Dynamics between order and chaos in conceptual models of glacial cycles
Takahito Mitsui, Kazuyuki Aihara
The dynamics of glacial cycles is studied in terms of the dynamical systems theory. We explore the dependence of the climate state on the phase of astronomical forcing by examining…
Nonchaotic Stagnant Motion in a Marginal Quasiperiodic Gradient System
Takahito Mitsui
A one-dimensional dynamical system with a marginal quasiperiodic gradient is presented as a mathematical extension of a nonuniform oscillator. The system exhibits a nonchaotic stag…
