Metastability of Northern Hemisphere Teleconnection Modes

Journal of the Atmospheric Sciences, 2015
Abstract This study applies a finite-element, bounded-variation, vector autoregressive method to assess midtropospheric flow regimes characterized by regime switches between metastable states. The flow is assessed in reanalysis data from three different reanalysis sets assimilating surface data only; surface and upper-air data; and ocean,

Implications of changes in the Northern Hemisphere circulation for the detection of anthropogenic climate change [PDF]

, 2000
The first principal component of Northern Hemisphere sea level pressure, known as the Arctic Oscillation (AO) index, has increased significantly in recent winters, and this change is associated with ∼30% of Northern Hemisphere January–March warming.

Marine‐Calibrated Chronology of Southern Laurentide Ice Sheet Advance and Retreat: ∼2,000‐Year Cycles Paced by Meltwater–Climate Feedback

Geophysical Research Letters, 2023
Climatic warming following the Last Glacial Maximum caused the southern Laurentide Ice Sheet (LIS) to begin ∼2,000‐year cycles of retreat and readvance whose cause remains ambiguous.

Trends and emissions of six perfluorocarbons in the Northern Hemisphere and Southern Hemisphere [PDF]

Atmospheric Chemistry and Physics, 2020
Abstract. Perfluorocarbons (PFCs) are potent greenhouse gases with global warming potentials up to several thousand times greater than CO2 on a 100-year time horizon. The lack of any significant sinks for PFCs means that they have long atmospheric lifetimes of the order of thousands of years.

Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]

, 2013
The early Late Pliocene (3.6 to ∼3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO₂ concentrations were comparable to today's and global climate was warmer.
