Linear versus Self-Sustained Interdecadal Thermohaline Variability in a Coupled Box Model
Recent studies of decadal/interdecadal climate variability suggested two main classes of mechanisms: selfsustained (supercritical) oscillations due to the internal nonlinearity of the ocean and linear (subcritical) thermohaline oscillations driven by stochastic atmospheric forcing. The authors use a coupled ocean–atmosphere meridional box model to carefully examine these two alternatives. It is...
متن کاملThermohaline circulation stability: a box model study - Part II: coupled atmosphere-ocean model
A thorough analysis of the stability of a coupled version of an inter-hemispheric 3-box model of Thermohaline Circulation (THC) is presented. This study follows a similarly structured analysis on an uncoupled version of the same model presented in Part I. The model consists of a northern high latitudes box, a tropical box, and a southern high latitudes box, which respectively can be thought as ...
متن کاملThermohaline Circulation Stability in a Coupled Land - Ocean - Atmosphere Box Model
Global climate reflects a complex interaction among the continents, the oceans and the atmosphere. Exactly how these interactions occur remains one of the great questions about the Earth system. To address this issue, a simple box model representing one hemisphere with land, ocean and atmosphere components is developed and analyzed. The specific question addressed is how the inclusion of separa...
متن کاملDecadal Variability in Coupled Sea-Ice–Thermohaline Circulation Systems*
An interdecadal oscillation in a coupled ocean–ice system was identified in a previous study. This paper extends that study to further examine the stability of the oscillation and the sensitivity of its frequency to various parameters and forcing fields. Three models are used: (i) an analytical box model; (ii) a two-dimensional model for the ocean thermohaline circulation (THC) coupled to a the...
متن کاملThermohaline Circulation Stability: A Box Model Study. Part I: Uncoupled Model. Part II: Coupled Atmosphere-Ocean Model
A thorough analysis of the stability of the uncoupled Rooth interhemispheric three-box model of thermohaline circulation (THC) is presented. The model consists of a northern high-latitude box, a tropical box, and a southern high-latitude box, which correspond to the northern, tropical, and southern Atlantic Ocean, respectively. Restoring boundary conditions are adopted for the temperature varia...
