Sentences with phrase «decadal oscillation shifted»

In 1976/77 the surface temperature of a vast area of the Pacific Ocean abruptly warmed by several degrees as the Pacific Decadal Oscillation shifted from «cool phase» to «warm phase».

Recently, the peer reviewed journal Nature took a stab at explaining «The Hiatus» by ultimately suggesting that the Pacific Decadal Oscillation shift to cooling was to blame.

Barry, will the recent Pacific Decadal Oscillation shift mask some (or a lot) of the warming in the pipeline?.

Not exact matches

In April 2008, scientists at NASA's Jet Propulsion Laboratory announced that while the La Niña was weakening, the Pacific Decadal Oscillation (PDO)-- a larger - scale, slower - cycling ocean pattern — had shifted to its cool phase.

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.

Phase shifts in the Pacific Decadal Oscillation can be readily detected in the long - term records of annual snowfall.

Plant drought - tolerant species in years with strong El Niño forecasts, particularly during Pacific Decadal Oscillation warm phase; plant trees that require sufficient water during establishment in La Niña years and during Pacific Decadal Oscillation cool phases Focus planting more in spring as fall planting becomes more difficult with reduced soil moisture and test different planting timings as springs shift earlier

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.»

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.

There are many outside factors that contribute to the problem like submarine volcanic activities, shifts in oceanic currents along with the decadal oscillation events responsible for El Mino and so on.

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.

The stepwise shift appearing in the temperature data in 1976 corresponds to a phase shift of the Pacific Decadal Oscillation from a negative phase to a positive phase.

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.

I have already provided examples of observed real world shifts in global temperature trend going back to 1960 that match very well with shifts in the balance between solar variation and the net global effect of all the separate oceanic oscillations (especially the Pacific Decadal Oscillation which is by far the largest).

This may be related to an ongoing shift in the Pacific Decadal Oscillation over spring and early summer this year.

The presence of the longer - term effects on Australian rainfall from oceanic shifts, such as the Pacific Decadal Oscillation (PDO) and Interdecadal Pacific Oscillation (IPO), make the analysis of this situation, and the teasing out of the AGW influence, a complex matter.

They include the Atlantic Multidecadal Oscillation (AMO) that exhibited a warm phase from 1930 - 1965, but with a transient drop between 1945 and 1948, a Pacific Decadal Oscillation (PDO) that shifted from warm to cold between 1942 and 1950, and a series of El Nino conditions from 1939 through 1942.

However, one analysis that has attempted to explain both the very large winter extents of 2012, 2013, and 2014, and the subsequent lower and near - average winter maximums in 2015 and 2016 has suggested that the El Niño Southern Oscillation and a Pacific trend called the Pacific Decadal Oscillation (a residual tendency toward El Niño or La Niña in the Pacific that shifts on multi-decadal timescales) may be linked to the change.
