Sentences with phrase «decadal climate shift»

Thanks to the availability of data from satellite altimetry, Argo floats, and moored buoys in the tropical Pacific, this decadal phase change is the best - observed decadal climate shift in history.

The recognition of decadal climate shifts are an example of better science — the new paradigm of dynamical complexity in climate.

http://earthobservatory.nasa.gov/IOTD/view.php?id=8703 Now I realize that I have quoted Josh Willis form the NASA site before — but this is one of the critical Earth systems for many reasons — perhaps least for the changes in global surface temperature trajectory associated with the decadal climate shifts.

There is far too much so - called noise to distinguish the so - called signal and the noise changes abruptly and significantly with these decadal climate shifts.

My essential point remains — the likelihood more than not of no warming for decades at least emerging from decadal climate shifts.

Not exact matches

Goddard thinks it may be an early indication of a big shift in the Pacific Decadal Oscillation (PDO), a kind of long - term El Niño - like pattern of climate variability.

The study stops short of attributing California's latest drought to changes in Arctic sea ice, partly because there are other phenomena that play a role, like warm sea surface temperatures and changes to the Pacific Decadal Oscillation, an atmospheric climate pattern that typically shifts every 20 to 30 years.

He thinks their movement may be an early indication of a big shift in the Pacific Decadal Oscillation (PDO), a long - term pattern of climate variability.

Nate, a member of the FI Board of Directors, is the leader for the Landscape Ecology Team at NOAA's Southwest Fisheries Science Center, and has expertise about decadal - scale climate variability and ecosystem regime shifts.

In the Swanson and Tsonis paper it is suggested that the decadal variations of the global mean temperature, the climate shifts, observed in the 20th century are basically caused by the synchronization of four modes.

More recent work is identifying climate shifts working through the El Niño - Southern Oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), Southern and Northern Annular Modes (SAM and NAM), Artic Oscillation (AO), Indian Ocean Dipole (IOD), North Pacific Oscillation (NPO) and other measures of ocean and atmospheric states.

Wu, Lee, and Liu (2005) said: «The 1970s North Pacific climate regime shift is marked by a notable transition from the persistent warming (cooling) condition over the central (eastern) North Pacific since the late 1960s toward the opposite condition around the mid 1970s... This large - scale decadal climatic regime shift has produced far - reaching impacts on both the physical and biological environment over the North Pacific and downstream over North America.»

The 1998/2001 climate shift was to a cooler state with increased cloud cover — and these prominent decadal modes last for 20 to 40 years.

Even after this is done, some longer term natural variations remain, most notably a phenomenon called the Pacific Decadal Oscillation (PDO) that causes irregular shifts in the climate roughly every few decades.

Thus a conservative estimate for the time taken to complete the LIA climatic shift to present - day climate is about 10 years, suggesting the LIA termination in alpine regions of central North America may have occurred on a relatively short (decadal) timescale.

Meehl, G. A., A. Hu, and B.D. Santer, 2008: The mid-1970s climate shift in the Pacific and the relative roles of forced versus inherent decadal variability, J. Climate, inclimate shift in the Pacific and the relative roles of forced versus inherent decadal variability, J. Climate, inClimate, in press.

Over the past 60 years, Alaska has warmed more than twice as rapidly as the rest of the United States, with state - wide average annual air temperature increasing by 3 °F and average winter temperature by 6 °F, with substantial year - to - year and regional variability.1 Most of the warming occurred around 1976 during a shift in a long - lived climate pattern (the Pacific Decadal Oscillation [PDO]-RRB- from a cooler pattern to a warmer one.

The latitudinal limits between those climates are shifting northward or southward according to cycles as seen on figure 21 - B for the USA [74]; this may explain the fear, expressed in the 1970s in many periodical and books, of an imminent glaciation; that fear faded after the reversal of the PDO (Pacific Decadal Oscillation) in 1977.

Component C, Predictability, mechanisms, and case studies: the organization and coordination of decadal climate predictability studies and of case studies of particular climate shifts and variations, including the study of the mechanisms that determine these behaviours

The CET data for the period indicate a distinct climate shift of some 0.35 degrees centigrade on a 50 year basis, but rather more on a decadal basis, so that well documented era can usefully be our benchmark for temperature comparisons, whilst demonstrating the usefulness of a decadal time scale in determining a change in the climate that is «noticeable» and has an impact on humans and nature.

The real problem with this is that climate is nonlinear — it shifts at decadal and longer periodicities to emergent states dependent on the interplay of control variables and sub-systems.
