Abrupt Change in Sahara Precipitation and the Associated Circulation Patterns

Abrupt Climate Change and Multistability of the Thermohaline Circulation

Ice core records suggest that the Earth’s climate has undergone rapid, catastrophic shifts on multiple occasions in geologically recent times. The multiplicity of steady states found in fluid convection models has led many to speculate that the changes may have been caused by transitions between different stable modes of ocean current patterns. This paper reviews analytical and numerical modeli...

Abrupt climate change and thermohaline circulation: mechanisms and predictability.

The ocean's thermohaline circulation has long been recognized as potentially unstable and has consequently been invoked as a potential cause of abrupt climate change on all timescales of decades and longer. However, fundamental aspects of thermohaline circulation changes remain poorly understood.

Abrupt and Persistent Declines in Regional Precipitation Patterns: Societal Implications and Geographic Patterns

Abrupt and persistent changes in regional climate patterns have happened in the past, and according to models, may happen again in the future. These sudden and prolonged shifts have negatively impacted the well being of people and can compromise the ability of societies to sustain into the future in a desirable way. It is therefore important to determine which places might be vulnerable to abru...

Role of the Bering Strait in the thermohaline circulation and abrupt climate change

[1] Here we investigate the role of the Bering Strait (BS) in the thermohaline circulation (THC) response to added freshwater forcing (hosing) in the subpolar North Atlantic, through analyzing simulations of a fully coupled climate model with an open and closed BS. Results show that the THC declines similarly with an open and closed BS during hosing. However, the recovery of the THC is delayed ...
