And he said it can be difficult to factor the effects of the Pacific Decadal Oscillation (PDO) into any climate studies, given that «high quality data» exists for fewer than two of its complete oscillations.

The data the researchers were interested in tracking revolved around four important climate indices: the Pacific Decadal Oscillation; the Multivariate El Niño Southern Oscillation Index, which includes both El Niño and La Niña; the Southern Annular Mode; and the Pacific North American Pattern.

Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 meaOscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 meaoscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).

Note especially Figure 2 and the related statement, «In 1976, a stepwise shift appears in the temperature data, which corresponds to a phase shift of the Pacific Decadal Oscillation from a negative phase to a positive phase.»

Thoman says the weather service has pretty good data collected over the past 65 years on the so - called Pacific Decadal Oscillation, or PDO, cycle that drives El Ninos and La Ninas.

As such, recent studies looking back at the past 30 years of data show a decadal modulation of El Niño Southern Oscillation (ENSO) stability, with the past decade characterized by higher - frequency and lower - amplitude El Niños than the previous ones [22].

Additionally, several climatological oscillatory mode data will be used as controls to assess the correlations between GCR flux, solar activity, and cloud cover: specifically the Atlantic Multidecadal Oscillation (AMO), the multivariate El Nino Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), the Pacific Decadal Oscillation (PDO), and the Quasi-Biennial Oscillation (QBO).

We show that a harmonic constituent model based on the major astronomical frequencies revealed in the aurora records and deduced from the natural gravitational oscillations of the solar system is able to forecast with a reasonable accuracy the decadal and multidecadal temperature oscillations from 1950 to 2010 using the temperature data before 1950, and vice versa.

He proposes a relationship between the Pacific Decadal Oscillation (PDO) and clouds by considering a variety of combinations of initial ocean temperature, ocean thickness, cloud feedback, and forcing by clouds (neglecting forcing by CO2 and the water vapor feedback entirely) in a simple energy balance model, and finds a relationship between PDO and clouds using 9 years of satellite data.
