Simulation of recent global temperature trends [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Observations show that global average tropospheric temperatures have been rising during the past century, with the most recent portion of record showing a sharp rise since the mid-1970s.

Effects of interdecadal climate variability on the oceanic ecosystems of the northeast Pacific Ocean [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): It is increasingly apparent that a major reorganization of the Northeast Pacific biota transpired following a climatic "regime shift" in the mid-1970s. In this paper, we characterize the effects of interdecadal climate forcing on the oceanic ecosystems of the northeastern Pacific Ocean.

Decadal hydroclimatic variability over western North America [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Variability of precipitation over North America on ENSO and decadal time scales is examined from several decades of precipitation and snow course records.

Terrestrial ecosystem response to interdecadal climate variability in the western United States [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): We argue that the most important climatically-driven terrestrial ecosystem changes are concentrated in annual- to decadal-scale episodic events. These rapid ecosystem responses to climate change are manifested as regionally synchronized disturbance events (eg, floods, fires, and insect outbreaks) and increased drought-caused plant mortality rates.

Paleorecords of interdecadal variability from mid-latitude varved sediments and tropical corals of the eastern Pacific [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Reconstruction of proxy variables from massive corals and varved sediments of the eastern Pacific allow us to compare variability in the ocean climate from equatorial and mid-latitude sites for a significantly longer period than is available from the instrumental record.

The terrestrial record of interdecadal climate variability in western North America [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Western North America is particularly rich in natural records of climate that have potential to reveal features of interdecadal climate variability.

Decadal climate variability over the North Pacific and North America: dynamics and predictability [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): The dynamics and predictability of decadal climate variability over the North Pacific and North America are investigated by analyzing various observational datasets and the output of a state-of-the-art coupled ocean-atmosphere general circulation model, which was integrated for 120 years.

Decadal variability over the North Pacific Ocean [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): In this study we use ocean and atmosphere datasets from observations and from an ocean general circulation model integration to examine decadal time scale variability that is centered in the Pacific basin. We know that decadal variability is likely to have a strong expression in the Pacific basin; for example, a marked "shift" of cool season climate in the mid-1970s introduced major changes in Pacific SST and atmospheric circulation, along with many other physical and biological properties.

Interdecadal shifting of the North Pacific jet stream - El Niño events [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Researchers have shown a step-like increase in worldwide sea surface temperatures (SSTs) in the mid-1970s. Wintertime (December through March) polar-front jet stream positions in the North Pacific will be presented for six moderate-to-very-strong El Niño events - three before the winter of 1975-76 (1965-66, 1968-69, 1972-73) and three after (1982-83, 1986-87, 1991-92).

Long-term changes in the equatorial Pacific trade winds [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Past work has shown that surface zonal equatorial wind stress, zonally integrated from one side of the Pacific to the other, is the key variable for estimating long-term El Niño behavior in the eastern Pacific. ... We used detrended COADS pressure in the eastern and western equatorial Pacific and post-1960 detrended Florida State University equatorial wind stress zonally averaged across the Pacific to verify this relationship.
