Sentences with phrase «pacific decadal trends»

Not exact matches

[11] Few attribute the decline in fog, and moreover, climate change, to the Pacific Decadal Oscillation, however, as the Pacific Decadal Oscillation is an oscillation moving heat through the climate system but neither creating nor retaining heat, it is not a cause of warming trends or declines in fog.

# 8220; This multi-year Pacific Decadal Oscillation «cool» trend can intensify La Niña or diminish El Niño impacts around the Pacific basin,» said Bill Patzert, an oceanographer and climatologist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. «The persistence of this large - scale pattern [in 2008] tells us there is much more than an isolated La Niña occurring in the Pacific Ocean.»

While that is possible, the so - called Pacific Decadal Oscillation (PDO) index that is used to characterize decadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sinceDecadal Oscillation (PDO) index that is used to characterize decadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal fluctuation since 1980).

No mention is made of ENSO or Pacific decadal variations that dominate interannual and decadal variability in the real world, and which are a key to understanding the recent hiatus, and recent trends that are not representative of longer - term trends, although frequently interpreted as such.

Seems that the most recent warming trend that begins just past the max trough of the Atlantic Multi-decadal lines up with the warming of the Pacific Decadal Oscillation during two of the main multi-centenial warm surges, the first one from about 1910 - 1940 and the 2nd stronger one from about 1970 - 2000.

So for multi-decadal trend, the tropical Pacific Decadal Oscillation accounts for only 0.1 C for the longer period of 1950 - 2012.

Mr. Steele points out how natural cycles, such as the Pacific Decadal Oscillation among many others, better fits the current climatological trend.

ENSO (El Nino Southern Oscillation) and PDO (Pacific Decadal Oscillation) help to explain short - term variations, but have no long - term trend, warming or otherwise.

Climatologies of Rocky Mountain snowpack are shown to be seasonally and regionally complex, with Pacific decadal variability positively reinforcing the anthropogenic warming trend.

Increasing abundances of Florisphaera profunda and Umbilicosphaera sibogae after 1970 reflect a warming trend and increased stratification within the basin associated with the warm phase of the Pacific Decadal Oscillation (PDO).

However the temperature trend correlates much better with the heat ventilating cycles of Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation.

It is highly likely that due to its effect on storm tracks and competing air masses, the AMO can explain most of the east coast's temperature trends in a manner similar to how the Pacific Decadal Oscillation controls the USA's west coast trends as published by Johnstone 2014.

Any natural change - points caused by cycles like the Pacific Decadal Oscillation looked like deviations relative to steadily rising trends of an increasingly populated region like Columbia, Maryland or Tahoe City.

There is decadal variability to ENSO and the Pacific more generally and they are associated with the trends of cooling and warming seen in the 20th century.

The method is a straight - forward application of the first law of thermodynamics and uses only the time - integral of sunspot count and 32 - year long up trends and down trends that have an amplitude of 0.45 C and are probably related to the Pacific Decadal Oscillation.

John Philips (13:43:35) «Trends» have become virtually meaningless lately, since the word has been so variably used, but try this: Eyeball the temperature curve as correlated to the Pacific Decadal Oscillation and you will see an excellent relationship with the cyclic cooling and warming phase of the PDO overlaid on a gradual warming trend emerging from the Little Ice Age.

The fact that the long - term trends in rainfall and Pacific SSTs are both positive, the opposite of their interannual relationship (Power et al., 1998), explains only a portion of why the correlation is reduced at decadal time scales.

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).

Can long - term cycles in ocean temperature such as the Pacific Decadal Oscillation explain the centennial trend?

The recent acceleration of ocean heat content is exaggerated due to the negative phase of the Pacific Decadal Oscillation happening on top of the long - term ocean warming trend.

[Short response: The Pacific Decadal Oscillation has not trended with temperature, and in addition, may simply be an artifact of past El Ninos.]

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.
