[1] In this paper for the first time I show that themultidecadal variations of observed tropical North Atlantic (TNA) sea surface temperature (SST) are strongly anticorrelated with those of the observedTNA subsurface ocean temperature, with long-term trends removed. I further show that the anticorrelated change between the TNA surface and subsurface temperature is a distinctive signature of the...

[1] This letter offers new evidence motivating a more serious consideration of the potential Arctic temperature responses as a consequence of the decadal, multidecadal and longer-term persistent forcing by the ever-changing solar irradiance both in terms of total solar irradiance (TSI, i.e., integrated over all wavelengths) and the related UV irradiance. The support for such a solar modulator c...

[1] The Atlantic Multidecadal Oscillation (AMO) is a near-global scale mode of observed multidecadal climate variability with alternating warm and cool phases over large parts of the Northern Hemisphere. Many prominent examples of regional multidecadal climate variability have been related to the AMO, such as North Eastern Brazilian and African Sahel rainfall, Atlantic hurricanes and North Amer...

It is well known that the El Niño-Southern Oscillation (ENSO) could affect precipitation anomalies in central-western Indian Ocean (CWIP) through modifying Walker circulation, with an Niño generally accompanied by enhanced CWIP. In this study, we find positive association modulated Atlantic Multidecadal (AMO). When ENSO and AMO are out-of-phase combinations (i.e., AMO-/El AMO+/La Niña), CWIP si...

Low frequency internal signals bring challenges to signify the role of anthropogenic factors in sea level rise and attain a certain accuracy trend acceleration estimations. Due both spatially temporally poor coverage relevant data sets, identification variability patterns is not straightforward. In this study, low (decadal multidecadal) change Fremantle tide gauge station analyzed using two cli...

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:...
