Early?to?Late Winter 20th Century North Atlantic Multidecadal Atmospheric Variability in Observations, CMIP5 and CMIP6

چکیده
The strong multidecadal variability in North Atlantic (NA) winter atmospheric circulation is poorly understood and appears too weak climate models. Recent research has shown peak over the NA late winter, particularly March, linked to (AMV) of ocean. Here a range indices are assessed provide comprehensive picture early-to-late low-frequency its representation latest generation models (Coupled Model Intercomparison Project Phase 6 [CMIP6]). As found for CMIP5, CMIP6 exhibit too-weak compared reanalysis data period 1862–2005. Consistent with previous research, eastern part westerly jet (U700NA) exhibits March. However, NA-wide speed NAO, model-reanalysis discrepancies strongest January February, associated ocean-atmosphere linkages.

Early 20th-century Arctic warming intensified by Pacific and Atlantic multidecadal variability.
With amplified warming and record sea ice loss, the Arctic is the canary of global warming. The historical Arctic warming is poorly understood, limiting our confidence in model projections. Specifically, Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing. Here, we show that the c...
متن کاملPredictability of North Atlantic Multidecadal Climate Variability
Atmospheric weather systems become unpredictable beyond a few weeks, but climate variations can be predictable over much longer periods because of the coupling of the ocean and atmosphere. With the use of a global coupled ocean-atmosphere model, it is shown that the North Atlantic may have climatic predictability on the order of a decade or longer. These results suggest that variations of the d...
متن کاملMultidecadal Variability of North Atlantic Temperature and Salinity during the Twentieth Century
Substantial changes occurred in the North Atlantic during the twentieth century. Here the authors demonstrate, through the analysis of a vast collection of observational data, that multidecadal fluctuations on time scales of 50–80 yr are prevalent in the upper 3000 m of the North Atlantic Ocean. Spatially averaged temperature and salinity from the 0–300and 1000–3000-m layers vary in opposition:...
متن کاملOn Multidecadal and Quasi-Decadal North Atlantic Variability
Observed sea surface temperatures (SSTs) in the North Atlantic from 1958 through 2000, as well as data from an ocean model simulation driven with the atmospheric variability observed during the same period, are examined using multichannel singular spectrum analysis. The two leading oscillatory modes are associated with a multidecadal and a quasi-decadal period. The former is connected to a basi...
متن کاملA predictability study of simulated North Atlantic multidecadal variability
The North Atlantic is one of the few places on the globe where the atmosphere is linked to the deep ocean through air—sea interaction. While the internal variability of the atmosphere by itself is only predictable over a period of one to two weeks, climate variations are potentially predictable for much longer periods of months or even years because of coupling with the ocean. This work present...
