The North Atlantic Oscillation is one of the most influential climatic modes in Northern Hemisphere. However, mechanism(s) standing behind its wide spectra variations still unknown despite numerous investigations. This paper presents evidence for a synchronization between secular geomagnetic field intensity and NAO long-term variability. Analysis connectivity sea-level pressure – point by point...

Decadal variations in summer drought events during 1956–2005 are examined over Eastern China to identify their leading variability modes and their linkages to the Pacific Decadal Oscillation (PDO), Atlantic Multi-decadal Oscillation (AMO), and global warming. The PDO influence is found to dominate China drought frequency from the 1960s to early 1990s via modulating the Western Pacific Subtropic...

[1] A global ocean general circulation model is used to estimate the magnitude of interannual variability in air-sea fluxes of CO2 and O2 from 1980–1998 and to examine the controlling mechanisms. The global variability in the air-sea flux of carbon (±0.5 10 grams Carbon yr 1 (PgC yr )) is forced by changes of DpCO2 and wind speeds related to the El Niño/Southern Oscillation (ENSO) cycle in the ...

The statistical relationship between the quasi-biennial oscillation (QBO) and tropical cyclone (TC) activity is explored, with a focus on the North Atlantic. Although there is a statistically significant relationship between the QBO and TCs in the Atlantic from the 1950s to the 1980s, as found by previous studies, that relationship is no longer present in later years. Several possibilities for ...

A large single-year reversal in the phase of the North Atlantic Oscillation (NAO) during 1996 led to a dramatic shift in the slope-water circulation patterns of the northwest (NW) Atlantic. Analyses of time-series data collected from the region over the past half century show that both physical and biological responses are commonly elicited by such phase reversals in the NAO. Here, we use a mod...
