Sentences with phrase «significant decadal variability»

The atmospheric warming is the factor that can best explain this consistency, up to ~ 0.7 °C since 1950 and more marked since 1976, while the trend in precipitation is much less homogeneous over this area and is affected by a significant decadal variability.

«The study reinforces the idea that looking at Arctic and Antarctic ice separately is the best way to understand decadal and long - term trends, because it suggests significant decadal and inter-decadal variability in southern hemisphere ice extent going back much further than the last 30 years.»

Willis has even stated that a smaller, but still possibly significant fraction of the annual to decadal heat content variability takes place below 700 meters.

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).

Because the long - term warming trends are highly significant relative to our estimates of the magnitude of natural variability, the current decadal period of stable global mean temperature does nothing to alter a fundamental conclusion from the AR4: warming has unequivocally been observed and documented.

Unforced natural cloud variability with significant interannual and decadal changes in the radiative flux.

«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric circulation.»»

It should be noted that we are not suggesting here that all decadal sea level variability is related to TWS, but do find TWS variability to play a significant role in sea level changes on the timescale of a decade.»

Some of these changes are significant for decadal variability of surface temperature.

Natural factors such as the Sun (84 papers), multi-decadal oceanic - atmospheric oscillations such as the NAO, AMO / PDO, ENSO (31 papers), decadal - scale cloud cover variations, and internal variability in general have exerted a significant influence on weather and climate changes during both the past and present.

This can be seen in the Pacific Ocean — a very significant driver of interannual to decadal hydrologic and climate variability — in changes in hydrology and ocean states around 1910, the mid 1940's, the late 1970's and after 1998.
