... instrumental record that exacerbates the detection of possible long-term changes in hurricane activity, which naturally exhibits strong multidecadal variations that are associated with the Atlantic Multidecadal Oscillation (AMO). The AMO, itself a major mode of climate variability, remains also poorly...

The time series exhibits significant cyclic components that can be related to two of the dominant internal modes of climate variability in the region: the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO). The NAO signal is associated with internal...

... (hence stronger summer westerlies). This mode is in turn correlated to the pronounced multidecadal oscillation in Mediterranean sea-surface temperature (related to the Atlantic Multidecadal Oscillation), suggesting that coupled ocean-atmosphere dynamics control the large-scale transport of dust...

... with a prominent 9-year peak that is commonly also found in modern temperature records and is present in the contemporary Atlantic Multidecadal Oscillation (AMO) index and Pacific Decadal Oscillation (PDO) index. These cyclicities are common to both ancient and modern climate records because they can be associated...

... ). Our reconstructed subsurface ocean temperature record shows some similarities with the Atlantic Multidecadal Oscillation (AMO; Figs. 3A and 3D ) over the past 100 yr. The AMO represents periodic variations in sea-surface temperature measurements identified across the North Atlantic basin ( Kerr, 2000...

... Holocene (ca. 11 ka); under this climate state, drought was strongly cyclic, recurringat frequencies that are similar to twentieth century multidecadal phase changes of thePacific Decadal Oscillation. This pattern remained consistent throughout much of the mid-Holocene, continuing until ca. 4.5 ka. After...

We generated a multidecade resolution record of alkenone sea surface temperature (SST) in the northwestern Pacific off central Japan during the Holocene. The SST record showed centennial and millennial variability with an amplitude of ~1 °C...

Western U.S. stations (KIP, TUC, and ANMO) show a primarily Pacific association, and U.S. East Coast and northern European stations (ESK, HRV, and KONO) have relatively minor Atlantic associations. Deep Antarctic stations (SBA, SPA/QSPA) show strong association with each other, but are only...
